PCB Assembly
Ordering Information
Pre-tested, fully assembled modules are
available:
PS3110 – NiMH module
PS3120 – Li Ion module
Please specify number of series cells when
ordering.
Quick Start
Follow these directions to assemble a pack with the PS3100 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 PS331 family of CMOS ASICs. The
negative cell string connection should always be connected first, followed by the cell string
positive connection. The remaining connections can then be made after the pack negative and
pack positive are securely connected to the module.

from W1 and W2. All others are signal only lines (24 to 22 AWG).
Step 3) Connect W1 (BN) to the most negative point on the battery cell stack.
Step 4) Connect W6 (BP) to the most positive point on the battery cell stack.
Step 5) Li Ion Only: Connect cell voltage pickups at W3, W4, W5 as required (see diagrams).
Step 6) Connect external connector to W7, W8, W9.
Step 7) Li Ion Only: Connect safety electronics between W2 and external connector OR between the most
positive point on the battery cell stack and the external connector.
Step 8) NiMH Only: Connect W2 to external connector. Connect most positive point on the battery stack
to the external connector.
Step 9) Program the assembled pack using PowerSmart's SBTool software and calibration board or info
board hardware and your *.p3I file. Default *.p3I files are available on the website
(www.powersmart.com).
Step 10) Calibrate the pack using the SBTool software and calibration board hardware. The pack is now
ready for use.
