MP2681

CC/CV Controller

with Full Protection and Indication

One Chip Solution for Power Tools Applications

The Future of Analog IC Technology

DESCRIPTION

FEATURES

•

Constant Voltage and Constant Current

Control

Pre-Charge Mode for Deeply-discharged

Battery

Automatic Battery Cell Detection

Two 1MHz Bandwidth Operational

Amplifiers Output Connected with OR Logic

Wide Input Voltage Range: 4.5V to 30V

Auto-Recharge

The MP2681 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 MP2681 automatically detects the battery

cell through a battery ID resistor and regulates

the battery voltage according to the

corresponding cell configurations: 3S1P, 3S2P,

4S1P, 4S2P, 5S1P and 5S2P. Then, the AC

adapter output is automatically regulated

according to the battery configuration chosen.

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 six pre-set

•

Charge On/Off Control

Programmable Internal Timer

Battery Temperature Monitoring

Charge Status Indication

Power Line Fault Detection

Over Temperature Protection

16-pin SOIC Package

APPLICATIONS

VID

values

representing

each

battery

configuration. The MP2681 charges the battery

in three phases: pre-charge, constant current

and constant voltage. Charge is terminated

when the current reaches a minimum set level.

An internal charge timer provides safety backup.

The MP2681 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.
