DESCRIPTION

FEATURES

•

Constant Voltage and Constant-Current

Control

Pre-Charge Mode for Deeply-Discharged

Batteries

Automatic Battery-Cell Detection

Two 1MHz Bandwidth Operational

Amplifiers Output Connected with OR Logic

Wide Input-Voltage Range: 5.0V to 30V

Auto-Recharge

The MP2681B is a highly integrated Li-ion or Li-

polymer switch-mode battery-charge controller

with full protection and status indication. This

part integrates a precision voltage reference

and charge status indications suitable for AC

adapter input and cradle charger applications.

•

The MP2681B detects automatically the battery

cell through a battery ID resistor and regulates

the battery voltage according to the

corresponding cell configurations: 3S, 4S, and

5S. Then, the AC adapter output is regulated

automatically according to the chosen battery

configuration. Additionally, if the battery pack

does not have an ID resistor, the charge

termination voltage can be configured by setting

a dedicated voltage to the ID pin, according to

the pre-set VID values representing the battery

configuration. The MP2681B charges the

battery in three phases: pre-charge, constant

current and constant voltage. Charge is

Charge On/Off Control

Programmable Internal Timer

Battery Temperature Monitoring

Charge-Status Indication

Power-Line Fault Detection

Over-Temperature Protection

16-pin SOIC Package

minimum set level. An internal charge timer

provides safety back-up. The MP2681B

provides a fixed pre-charge mode for deeply-

discharged batteries and safety features that

include battery temperature monitoring, NTC

control, charge time-out, and fault control.

MP2681B is available in a 16-pin SOIC

package.
