Control of Lithium Ion Batteries (switching regulator secondary) (two cells)

Monolithic IC MM1357

Outline

This IC is used to control two-cell chargers and the secondary side of switching regulators; it features

enhanced functions for current switching and for overcharge detection and other kinds of protection. The

control output is capable of driving a photocoupler LED. The charging current can be switched between high

and low currents, and each can also be varied externally.

Features

2. Charging current (switchable between high and low levels, variable)

3. Reference voltage

: Can be set externally

High : 320mV typ.

Low : 145mV typ.

: 1.207V typ.

Package

SOP-14B

Applications

1. Switching regulator

2. AC adapter

3. Lithium ion battery charger
