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.
