Overview

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