GR5302
Monitor and Timing Management for 4-Loop NiMH
Battery Charger
Features
● 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
Description
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.
