GENERAL DESCRIPTION
The PS5162 module is a complete smart battery
controller subsystem based on the Microchip PS501
field reprogrammable battery manager with patented
Accuron® technology. The module is designed to oper-
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.
