Preliminary Product Brief and AS3603/04 Delta Sheet, Confidential

AS3604

AS3603 with Momentary Power Loss Detection, synchronous DCDC

and increased driving capability of the LDOs

General Description

−

Programmable Constant Voltage Charging

Programmable Pulse Charging

Safety Functions (Low Battery Shutdown)

Operation without Battery

The AS3604 is based on the architecture of the

AS3603. It has additional functions like momentary

power loss detection, a synchronous DCDC buck

converter, charger resume operation and increased

driving capability of the LDOs.

No-Battery Detection

Can regulate the current through the

battery or from the charger

Charger Input Overvoltage protection

(6V)

Key Features

−

The AS3604 features all the functions of the

AS3603 with the following additions (marked with

boldface italcs):

−

Shutdown even with connected charger

Charger Resume operation

Charger Interrupts (Inserted, Removed,

Overvoltage, Resume)

ꢀ

Momentary Power Loss Detection
