GENERAL DESCRIPTION

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.

Step 1) Configure the module for optional external

thermistor

use.

PS5100

modules

are

shipped configured to use the internal

temperature

sensor

only.

add

external thermistor to the board, remove

resistor R16 and connect the thermistor

across via TN and TR. A parameter change

is required to enable the external thermistor

measurements. Bit 5 of Flags1 must be

cleared.

Step 2) Connect wires to module. Use large

diameter wire (18 AWG-20 AWG) for

current carrying lines from VR and V1. All

others are signal only lines (24 to 22 AWG).

Step 3) Connect V1 to the most positive point on

the battery cell stack.

Step 4) Connect VR to the most negative point on

the battery cell stack.

Step 5) Connect external connector to BN, T, C, D

and BP.

Step 6) Program

the

assembled

pack

using

Microchip’s PowerTool™ 500 software and

PowerCal™ 2 board or PowerInfo™ 2

board hardware. The module is shipped

with default configuration values for a six

series cell pack. The Configuration Wizard

guides the user through basic configuration

and initial download. All of the configuration

parameters can be changed at will using

the utilities on the Parameters page in the

PowerTool 500 software.

Step 7) Calibrate the pack using the PowerTool 500

software and PowerCal 2 board hardware.

The pack is now ready for use.
