AIC1761/1766

BATTERY CHARGE CONTROLLER

SPEC NO: DS-1761-02

ꢀ^DESCRIPTION

ꢀ^FEATURES

ꢀ

The AIC1761/1766 fast charge controller IC is

designed for intelligent charging of NiMH or NiCd

batteries without overcharging. It detects a voltage

drop (-∆V) occurring in the final stage of a fast

charging cycle and correspondingly controls the

charging current. Fast charge can also be cut off

by a peak voltage timer (0∆V).

Reliable Fast Charge Control of NiMH/NiCd Bat-

teries.

Quick and Easy Testing for Production.

Fast Charge Termination by:

ꢀ

1. Accurate -∆V Detection Level with Respect to

Peak Battery Voltage Value.

2. Peak Voltage Timer (0∆V).

The detection of -∆V is a very reliable method to

terminate fast charging for NiMH and NiCd batter-

ies. The AIC1761/1766 uses -∆V detection as one

of primary decisions for fast charge cut-off. The -

∆V value for the AIC1761 is as small as 16mV per

Adjustable Fast Charge Safety Timer.

Protection against Temperature Fault.

The

Wide Operation Voltage Range: 9V to 18V, no Ex-

tra Regulator Needed.

ꢀ

-∆V value for the AIC1766 is as small as 4mV per

cell, particularly suitable for NiMH as well as the

NiCd batteries. The peak voltage timer is particu-

larly useful when the voltage drop at the end of

charge for some batteries, e.g. NiMH cells, is not

pronounced enough for reliable detection. An ad-

justable safety timer (3 settings) is used as a back-

up termination method. Provisions are made with

the AIC1761/1766 to prevent fast charge under

temperature fault conditions. Two LED outputs are

used to indicate the charging status. Another flash

LED output can be used alone to indicate charge

status.

Large Battery Voltage Detection Range: 0.65V to

3.7V.

LED Drivers to Indicate Charge Status or Fault

Conditions.
