SMBus Interfaced Battery Charger with Internal FETs

ISL95871C

Features

The ISL95871C is a highly integrated Lithium-ion battery charger

controller, programmable over the System Management Bus

(SMBus) with internal switching FETs. High efficiency is achieved

with a DC/DC synchronous-rectifier buck converter, equipped with

diode emulation for enhanced light load efficiency and system bus

boosting prevention. The ISL95871C charges one to four

Lithium-ion series cells, and delivers up to 8A charge current.

Integrated MOSFETs and bootstrap diode result in fewer

components and smaller implementation area. Low offset

current-sense amplifiers provide high accuracy with 10mΩ sense

resistors. The ISL95871C provides 0.5% battery voltage accuracy.

• Internal Synchronous Buck Output Stage Power FETs

• 0.5% Battery Voltage Accuracy

• 3% Adapter Current Limit Accuracy

• 3% Charge Current Accuracy

• SMBus 2-Wire Serial Interface

• Battery Short Circuit Protection

• Fast Response for Pulse-Charging

• Fast System-Load Transient Response

• Monitor Outputs

The ISL95871C also provides a digital output that indicates the

presence of the AC-adapter as well as an analog output which

indicates the adapter current within 4% accuracy.

- Adapter Current (3% Accuracy)

- AC-Adapter Detection

• 11-Bit Battery Voltage Setting

Applications
