Product Details

Battery Protection IC

Description

The SL435 battery protection IC is designed to protect lithium-ion/polymer battery from damage or degrading the lifetime due to overcharge, overdischarge, and/or overcurrent for one-cell lithium-ion/polymer battery powered systems, such as cellular phones. The ultra-small package and less required external components make it ideal to integrate the SL435 into the limited space of battery pack. The accurate ±25mV overcharging detection voltage ensures safe and full utilization charging. The very low standby current drains little current from the cell while in storage.

Features

Reduction in Board Size due to Miniature Package SOT-23-6.

Ultra-Low Quiescent Current at 3μA  (Vcc=3.9V).

Two Detection Levels for Overcurrent

Protection.

Auto recovery

0v charging

Precision Overcharge Protection Voltage 4.425V ± 25mV for the SL435

Load Detection Function during Overcharge Mode.

Delay times are generated by internal circuits. No external capacitors required.
