Overview

GR5301 Monitor and Timing Management for 2-Parallel NiMH Battery Charger Features ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● 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.
Charges 1 to 2 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 Portable computer, cellular phone and PDA Charging docks and cradles Portable consumer electronics Desktop/standalone charger (AAA/AA) Digital still camera Music players (MP3) Game Toy Emergency light Ordering and Marking Information SOP-14 Code 1 8 9 A B G H I J Year 2008 2009 2010 2011 2016 2017 2018 2019 ● ● ● Code 2 1 2 3 4 9 A B C Month Jan.
