a resistor divider. The maximum output current is

set with a current sense resistor according to

charging current requirements.

The SPV1040 protects itself and other application

devices by stopping the PWM switching if either

the maximum current threshold (up to 1.8 A) is

reached or the maximum temperature limit (up to

155 °C) is exceeded.

An additional built-in feature of the SPV1040 is

the input source reverse polarity protection, which

prevents damage in case of reverse connection of

the solar panel at the input.

SPV1040TTR

Description

The SPV1040 device is a low power, low voltage,

monolithic step-up converter with an input voltage

range from 0.3 V to 5.5 V, and is capable of

maximizing the energy generated by even a single

solar cell (or fuel cell), where low input voltage

handling capability is extremely important.

Thanks to the embedded MPPT algorithm, even

under varying environmental conditions (such as

irradiation, dirt, temperature) the SPV1040 offers

maximum efficiency in terms of power harvested

from the cells and transferred to the output.

The device employs an input voltage regulation

loop, which fixes the charging battery voltage via
