The PS5100 module is a complete Smart Battery controller subsystem based on the Microchip PS501 battery manager with patented Accuron® technology. The module is designed to operate in a battery pack consisting of six (6) to twelve (12) series connected Ni-based cells. The module consists of the Microchip PS501 battery manager IC with a four LED SOC display and an optional connection for an external thermistor. 1.1 Quick Start – Pack Assembly Follow these directions to assemble a pack with the PS5100 module. • Use standard precautions when handling static sensitive devices. • Modules should be connected to battery cells in the order indicated below to insure proper start-up and operation. Wires should be attached to the modules first and then connected to the battery cells as instructed. • The connection sequence is critical to successful use of the PS501 family of CMOS ASICs. The pack positive should be securely connected to the module first, followed by pack negative.
