1.0 GENERAL DESCRIPTION
The PS5163 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
operate in a battery pack consisting of three (3) series
connected 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
PS5163 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 cells
from most positive to least positive and finally,
pack negative.
Step 1) Configure the module for optional external
thermistor use. PS5163 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 diameter
wire (18 AWG-20 AWG) for current carrying
lines from VR, V1, B+ and BN. All others are
signal only lines (24 to 22 AWG).
Step 3) Connect external connector to BN, T, C, D
and B+.
Step 4) Connect V1 to the most positive point on the
battery cell stack.
Step 5) Connect the negative end of the top-most
cell to V2 and the negative end of the second
cell to V3.
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.

2.0 FUNCTIONAL DESCRIPTION
2.1 PS501 Fuel Gauge
The module fuel gauge provides State-Of-Charge
(SOC) and battery status data in accordance with the
SMBus standards version 1.1. The PS501 monitors the
cell voltages, battery temperature and current to deter-
mine SOC and battery status. The State-Of-Charge
calculations are compensated for cell self-discharge.
The remaining time calculation is compensated for
temperature and discharge rate. The parameters for
determining battery status flags and alarm thresholds
are all programmable, as is the battery design capacity
and the battery performance model data. Please refer
to the “PS501 Data Sheet” (DS21818) for details on
configuring the PS501 device.
2.2 Primary Safety
The primary safety circuit provides cell protection from
conditions of overcharge, overdischarge and over-
current. The analog safety IC measures individual cell
voltages, current and voltage across the safety FETs.
These values are compared against internal reference
values and the gates of two N-channel power
MOSFETs are controlled based on the comparison
results.
