Charging System Safety Circuit

Features

The ISL9212 is an integrated circuit (IC) optimized to provide

a Li-ion battery redundant safety protection from failures of a

charging system. The IC monitors the input voltage, the

battery voltage, and the charge current. When any of the

three parameters exceeds its limit, the IC turns off an internal

P-Channel MOSFET to remove the power from the charging

system. In addition to the above protected parameters, the

IC also monitors its own internal temperature and turns off

the P-Channel MOSFET when the die temperature exceeds

+140°C. Together with the battery charger IC and the

protection module in a battery pack, the charging system

using the ISL9212 has triple-level protection and is two-fault

tolerant.

• Fully Integrated Protection Circuit for Three Protection

Variables

- User Programmable Overcurrent Protection Threshold

- Input Overvoltage Protection in Less Than 1µs

- Battery Overvoltage Protection

• High Immunity of False Triggering Under Transients

• High Accuracy Protection Thresholds

• Warning Output to Indicate the Occurrence of Faults

• Enable Input

• Thermal Enhanced TDFN Package

• Pb-Free (RoHS Compliant)

The IC is designed to turn on the internal PFET slowly to

avoid in-rush current at power-up but will turn off the PFET

quickly when input overvoltage is detected, in order to

remove the power before any damage occurs. The ISL9212

has a logic warning output to indicate the fault and an enable

input to allow the system to remove the input power.

Applications

• Cell Phones

• Digital Still Cameras

• PDAs and Smart Phones

• Portable Instruments
