PS051 Datasheet, PDF (2/8 Pages) Microchip Technology – PowerInfo 2 Configuration Interface

PS051
1.0 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.
2.0 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.
3.0 PS700Driver SETUP
The software driver for PS700 was developed for a
PIC^® microcontroller and can be installed on the
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
PS051 with another PowerSmart^® product, such as
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.
