Linear Charger for 1Cell Li-ion Battery with System-path IC MM3538AL
Linear Charger for 1Cell Li-ion Battery with System-path IC
Monolithic IC MM3538AL
Outline
This IC is a linear charging control IC with built-in system paths, and includes a chip with system path function and lithium ion/lithium polymer secondary battery charging function. This IC features a built-in load switch with overvoltage detection function and input current limit required for system paths, and built-in power FETs, backflow prevention diodes, and current sensor function required for charging and discharging. The IC comes equipped with an adapter and USB automatic recognition function, and allows the individual settings for charging control voltage and current with I2 C communication.
