PRODUCT OVERVIEW

PowerCal 2 is a powerful, easy to use hardware

platform that supports configuration, calibration and

test of Microchip PS7XX and PS5XX ICs. It operates

under the control of Microchip’s development/test

software interfaced to a Windows PC.

The PowerCal 2 board facilitates serial or USB com-

munication between the PC and the SMBus battery

interface. Whether connected to the PC’s serial (RS-232)

or USB port, the PowerCal 2 board must be powered

through an external 12V DC power supply.

GENERAL SETUP

The Microchip PowerCal 2 platform facilitates com-

munication between a battery containing a Microchip

PS5XX or PS7XX IC and a PC running Microchip’s

development/test

software.

The

information

that

follows will guide you through the setup of the various

features available.

2.1

Connections

• P1 – Serial (RS-232)

•J1 – USB

• J2 – 12V DC power supply

• TBP – Pluggable terminal block for device under

test. Looking into the connector on the board, the

pins from left to right are:

- V+: Battery pack positive

- C: SMBus clock

- D: SMBus data

-T:

T-pin

- V-: Battery pack negative

• TBV – Pluggable terminal block for individual cell

voltages. Use depends on the number of series

cells in a Lithium pack. Looking into the connector

on the board, the pins from left to

right are:

- VC4: Top of fourth series cell in pack

- VC3: Top of third series cell in pack

- VC2: Top of second series cell in pack

- VC1: Battery pack positive

2.2

Jumpers

• ADR – Jumper for board address identification

USB Setup

Connect the USB cable from J1 on the PowerCal 2

board to the USB port on the PC. Connect a 12V DC

power supply to J2 and plug it into the electrical outlet.

The board is now powered. Attach your battery to the

TBP connector and launch the Microchip development/

test software on the PC.

2.4

RS-232 Setup

Connect the serial cable from P1 on the PowerCal 2

board to the RS-232 port on the PC. Connect a 12V DC

power supply to J2 and plug it into the electrical outlet.

The board is now powered. Attach your battery to the

TBP connector and launch the Microchip development/

test software on the PC.

2.5

Individual Cell Voltage Setup

(Optional)

Connections from the individual cell voltages of a

Lithium pack can be attached at TBV to measure and

calibrate the individual cell voltages of the series cells

in the pack. Unused cell voltages should be connected

to V- during VC calibration.
