Preliminary GR5302

Monitor and Timing Management for 4-Loop NiMH

Battery Charger

Description

Features

The GR5302 is ideal for standalone charging of

4-loop NiMH packs (AA or AAA NiMH loose cells),

NiCd cells can also be charged. Temperature,

voltage and charge time are monitored to provide

proper fast/slow charging control algorithms for

Nickel Metal Hydride (NiMH) batteries. The GR5302

detects the battery chemistry and proceeds with the

optimal charging and termination algorithms. This

process eliminates undesirable undercharged or

overcharged conditions and allows accurate and

safe termination of fast/slow charge. Battery tests

are included to detect defective or inappropriate

cells such as alkaline primary batteries. The

GR5302 series support four loops charging topology,

with four independent monitoring and controls.

Charges 1 to 4 NiMH packs

Detects and avoids charging alkaline cells

Monitors voltage, temperature and time for

safety and secondary termination

Drivers PNP type pass element

Pre-charge qualification for detecting shorted,

damaged, or deeply depleted cells

Automatic recharge keeps batteries charged

Optional temperature qualified charging

Applications

NiMH battery charger for AAA/AA cells
