Ordering and Marking Information
Description
The GR5301 is ideal for standalone charging of 1 or
2 or 4 of 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 GR5301
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
GR5301 supports two loops charging topology, with
independent monitoring and control of each loop.
