MM3358 Datasheet (MITSUMI) - Lithium-ion battery charge controller

MM3358, Lithium-ion battery charge controller

MITSUMI Lithium-Ion Battery Charge Control IC MM3358 Lithium-Ion Battery Charge Control IC Monolithic IC MM3358 Outline This IC is a linear charge control IC for 1-cell Lithium-Ion and lithium-polymer batteries.

It incorporates a power MOSFET and a reverse-current block circuit for easy implementation of charge control of Lithium-Ion and Lithium-polymer batteries without an external sense resistor and a reverseblocking diode.

The chip temperature detection function can limit the temperature r
