PRODUCT OVERVIEW

The PowerInfo 2 board is a simple, easy to use hard-

ware interface that supports configuration, verification

and test of Microchip PS70X and PS5XX ICs. It operates

under the control of Microchip’s development/test

software interfaced to a Windows PC.

The PowerInfo 2 board facilitates serial or USB com-

munication between the PC and the SMBus battery

interface. If connected to the PC’s serial (RS-232) port,

the PowerInfo 2 board must be powered through an

external 12V DC power supply. If connected through a

USB port, no additional power is required.

GENERAL SETUP

The Microchip PowerInfo 2 interface facilitates commu-

nication between a battery containing a Microchip

PS5XX or PS70X 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 (used with serial

connection only)

• TB1 – Pluggable terminal block for device under

test. Looking into the connector on the board, the

pins from left to right are:

- V+ (VP): Battery pack positive

- C: SMBus clock

- D: SMBus data

-T: T-pin

- V- (VN): Battery pack negative

• TB2 – External charger or load connection

2.2

Jumpers

• ADR – Jumper for board address identification

2.3

USB Setup

The preferred method to connect PowerInfo 2 to the PC

is through the USB port. Connect the USB cable from

J1 on the PowerInfo 2 board to the USB port on the PC.

The board is now powered through the USB connec-

tion. Attach your battery to the TB1 connector and

launch the Microchip development/test software on the

PC.

2.4

RS-232 Setup

Connect the serial cable from P1 on the PowerInfo 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

TB1 connector and launch the Microchip development/

test software on the PC.

2.5

Charger/Load Setup (Optional)

A battery charger or a load can be attached at TB2 to

exercise the device under test.

PS700Driver SETUP

The software driver for PS700 was developed for a

PowerInfo 2 board when using a PS705X module

board or a PS7070 evaluation board. This software

driver is distributed on a PIC16F876 when a license

agreement has been executed.

3.1

Installing PS700Driver

Disconnect the PS051 from power and PC. Remove

the PIC microcontroller at location U1. Keep this IC in

a safe place as it must be replaced to operate the

PS501. Install the PS700Driver at location U1. The

PowerInfo 2 board can now be used with the PS700

development products.

3.2

Removing PS700Driver

To use the PS051 with another PowerSmart product,

such as PS501, the PS700Driver must be removed and

the PIC microcontroller originally located at U1

replaced. Disconnect the PS051 from power and PC.

Remove the PS700Driver at location U1. Install the

original PIC microcontroller and reconnect PC and

power connections.
