GENERAL DESCRIPTION

The PS5162 module is a complete smart battery

controller subsystem based on the Microchip PS501

field reprogrammable battery manager with patented

ate in a battery pack consisting of two (2) series con-

nected Li-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

PS5162 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 the intermediate cell

connection and then pack negative.

Step 1) Configure the module for optional external

thermistor

use.

PS5162

modules

are

shipped configured to use the internal tem-

perature sensor only. To add an external

thermistor to the board, remove resistor

R16 (side 2) and connect the thermistor

across via TN and TR.

Step 2) Connect wires to module. Use large diame-

ter wire (18 AWG-20 AWG) for current

carrying lines from VR, V1, BP and BN. All

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

Step 3) Connect external connector to BN, T, C, D

and BP.

Step 4) Connect V1 to the most positive point on

the battery cell stack.

Step 5) Connect V2 to the middle of the cell stack.

Step 6) Connect VR to the most negative point on

the battery cell stack.

Step 7) Program

the

assembled

pack

using

Microchip’s

software

and

PowerCal™

board or PowerInfo™ board hardware.

The memory parameters can be changed at

will using the utilities on the memory page in

the software.

Step 8) Calibrate the pack using the software and

PowerCal™ board hardware. The pack is

now ready for use.
