■GENERAL DESCRIPTION

■FEATURES

Detect Voltage Range : 1.6V ~ 5.0V, +2%

(100mV increments)

Hysteresis Range : V

x 5%, TYP.

(XC6101~XC6107)

x 0.1%, TYP.

(XC6111~XC6117)

Operating Voltage Range : 1.0V ~ 6.0V

Detect Voltage Temperature

Characteristics : +100ppm/

C (TYP.)

Output Configuration : N-channel open drain,

CMOS

Watchdog Pin : Watchdog input

If watchdog input maintains

‘H’ or ‘L’ within the watchdog

timeout period, a reset signal

is output to the RESET

output pin

Manual Reset Pin : When driven ‘H’ to ‘L’level

signal, the MRB pin voltage

asserts forced reset on the

output pin.

Release Delay Time : 1.6sec, 400msec, 200msec,

100msec, 50msec, 25msec,

3.13msec (TYP.) can be

selectable.

Watchdog Timeout Period : 1.6sec, 400msec, 200msec,

100msec, 50msec,

6.25msec (TYP.) can be

selectable.

The XC6101~XC6107, XC6111~XC6117 series are

groups of high-precision, low current consumption voltage

detectors with manual reset input function and watchdog

functions incorporating CMOS process technology. The

series consist of a reference voltage source, delay circuit,

comparator, and output driver.

With the built-in delay circuit, the XC6101 ~ XC6107,

XC6111 ~ XC6117 series’ ICs do not require any external

components to output signals with release delay time.

Moreover, with the manual reset function, reset can be

asserted at any time. The ICs produce two types of

output; V

DFL

(low when detected) and V

DFH

(high when

detected).

With the XC6101 ~ XC6105, XC6111 ~ XC6115 series’

ICs, the WD pin can be left open if the watchdog function

is not used.

Whenever the watchdog pin is opened, the internal

counter clears before the watchdog timeout occurs.

Since the manual reset pin is internally pulled up to the V

pin voltage level, the ICs can be used with the manual

reset pin left unconnected if the pin is unused.

The detect voltages are internally fixed 1.6V ~ 5.0V in

increments of 100mV, using laser trimming technology.

Six watchdog timeout period settings are available in a

range from 6.25msec to 1.6sec.

Seven release delay time 1 are available in a range from

3.13msec to 1.6sec.

* Not necessary with CMOS output products.

XC6101~XC6107, XC6111~XC6117 Series

The XC6101~XC6107, XC6111~XC6117 series compare, using the error amplifier, the voltage of the internal voltage

■OPERATIONAL EXPLANATION

reference source with the voltage divided by R1, R2 and R3 connected to the V

pin. The resulting output signal from the

error amplifier activates the watchdog logic, manual reset logic, delay circuit and the output driver. When the V

pin voltage

gradually falls and finally reaches the detect voltage, the RESETB pin output goes from high to low in the case of the V

DFL

type

ICs, and the RESET pin output goes from low to high in the case of the V

DFH

type ICs.

* V

DFL

(RESETB) type - output signal: Low when detected.

The RESETB pin output goes from high to low whenever the V

pin voltage falls below the detect voltage, or whenever the

MRB pin is driven from high to low. The RESETB pin remains low for the release delay time (T

) after the V

pin voltage

reaches the release voltage. If neither rising nor falling signals are applied to the WD pin within the watchdog timeout period,

the RESETB pin output remains low for the release delay time (T

), and thereafter the RESET pin outputs high level signal.

* V

DFH

(RESET) type – output signal: High when detected.

The RESET pin output goes from low to high whenever the V

pin voltage falls below the detect voltage, or whenever the

MRB pin is driven from high to low. The RESET pin remains high for the release delay time (T

) after the V

pin voltage

reaches the release voltage. If neither rising nor falling signals are applied to the WD pin within the watchdog timeout period,

the V

OUT

pin output remains high for the release delay time (T

), and thereafter the RESET pin outputs low level signal.

When the internal comparator output is high, the NMOS transistor connected in parallel to R3 is turned ON, activating the

hysteresis circuit. The difference between the release and detect voltages represents the hysteresis range, as shown by the

following calculations:

(detect voltage) = (R1+R2+R3) x Vref(R2+R3)

(release voltage) = (R1+R2) x Vref(R2)

HYS

(hysteresis range)=V

-V

(V)

> V

* Detect voltage (V

) includes conditions of both V

DFL

(low when detected) and V

DFH

(high when detected).

* Please refer to the block diagrams for R1, R2, R3 and Vref.

Hysteresis range is selectable from V

x 0.05V (XC6101~XC6107) or V

x 0.001V (XC6111~XC6117).

The XC6101~XC6107, XC6111~XC6117 series use a watchdog timer to detect malfunction or “runaway” of the

microprocessor. If neither rising nor falling signals are applied from the microprocessor within the watchdog timeout period,

the RESETB/RESET pin output maintains the detection state for the release delay time (T

), and thereafter the

RESET/RESETB pin output returns to the release state (Please refer to the FUNCTION CHART). The timer in the watchdog

is then restarted. Six watchdog timeout period settings are available in 1.6sec, 400msec, 200msec, 100msec, 50msec,

6.25msec.

Using the MRB pin input, the RESET/RESETB pin signal can be forced to the detection state. When the MRB pin is driven

from high to low, the RESETB pin output goes from high to low in the case of the V

DFL

type ICs, and the RESET pin output

goes from low to high in the case of the V

DFH

type. Even after the MRB pin is driven back high, the RESET/RESETBpin

output maintains the detection state for the release delay time (T

). Since the MRB pin is internally pulled up to the V

voltage level, leave the MRB pin open if unused (Please refer to the FUNCTION CHART). A diode, which is an input

protection element, is connected between the MRB pin and V

pin. Therefore, if the MRB pin is applied voltage that exceeds

, the current will flow to V

through the diode. Please use this IC within the stated maximum ratings (V

-0.3 ~ V

+0.3)

on the MRB pin.

Release delay time (T

) is the time that elapses from when the V

pin reaches the release voltage, or when the watchdog

timeout period expires with no rising signal applied to the WD pin, until the RESET/RESETB pin output is released from the

detection state. Seven release delay time (T

) watchdog timeout period settings are available in 1.6sec, 400msec,

200msec, 100msec, 50msec, 25msec, 3.13msec.

Detect Delay Time (T

) is the time that elapses from when the V

pin voltage falls to the detect voltage until the RESET/

RESETB pin output goes into the detection state.

■NOTES ON USE

1. Please use this IC within the stated maximum ratings. Operation beyond these limits may cause degrading or permanent

damage to the device.

2. When a resistor is connected between the V

pin and the input, the V

voltage drops while the IC is operating and a

malfunction may occur as a result of the IC’s through current. For the CMOS output products, the V

voltage drops while

the IC is operating and malfunction may occur as a result of the IC’s output current. Please be careful with using the

XC6111~XC6117 series (without hysteresis).

3. In order to stabilize the IC’s operations, please ensure that the V

pin’s input frequency’s rise and fall times are more than

1 µ sec/V.

4. Noise at the power supply may cause a malfunction of the watchdog operation or the circuit. In such case, please

strength the line between V

and the GND pin and connect about 0.22µF of a capacitor between the V

pin and the GND

pin.

5. Protecting against a malfunction while the watchdog time out period, an ignoring time (no reaction time) occurs to the rise

and fall times. Referring to the figure below, the ignoring time (no reaction time) lasts for 900µsec at maximum.
