PRODUCT OVERVIEW

The PS2070 evaluation board is a complete charger
evaluation circuit subsystem based on the Microchip
PS200 charge controller. The board is designed to
operate with a rechargeable battery pack consisting of
lithium based, nickel based or lead acid cells. The
board includes the Microchip PS200 battery monitor IC
in a socket, a 100 mOhm sense resistor and power
components to enable charging currents to a maximum
of 2.0A.

2.0

GENERAL SETUP

The Microchip PS2070 evaluation board plugs directly
into a PowerInfo 2 interface board or PowerCal 2
calibration board. These development tools, connected
to a PC running PowerTool™ 200 (PS020) develop-
ment software, form a complete PS200 battery charger
evaluation environment. The information that follows
will guide you through the setup of the various features
available. Please refer to the PowerInfo 2 or
PowerCal 2 data sheet for information on setting up
those products.

2.1

Connectors

• JBat – Battery input connector. The battery pack 

to be charged is connected here. Looking into the 
connector on the board, the pins from left to right 
are:

- BAT+: Battery pack positive

- CLK:

SMBus clock

- DTA:

SMBus data

- TMP:

Temperature

- GND:

Battery pack negative

• PHost – Charger host interface. The PowerInfo 2 

or PowerCal 2 is connected here. Looking into the 
connector on the board, the pins from left to right 
are:

- GND:

Battery pack negative

- TMP:

Temperature

- DTA:

SMBus data

- CLK:

SMBus clock

- BAT+: Battery pack positive

• J1 – In-Circuit Serial Programming (ICSP) 

interface. The PS200 Flash memory can be 
reprogrammed via this interface. This is only 
necessary to upgrade to a newer firmware 
revision or install firmware for a different 
rechargeable chemistry.

• J3 – Charger DC power supply input. Input volt-

age range is 18 to 22 V

DC

. The supply must be 

current limited or fused to a maximum of 2.5A.

2.2

Jumpers

• JP2 – Jumper to configure board for standard 

operation with PS200 pin 2 (LED 2) connected to 
the red LED or connected to PHost CLK for 
communication with PowerTool 200 PC software.

• JP18 – Jumper to disconnect the overvoltage 

protection divider from PS200 pin 18 (VOVP). This 
allows pin 18 to be used for ICSP.

• JP19 – Jumper to disconnect the temperature 

divider from PS200 pin 19 (TEMP). This allows 
pin 19 to be used for ICSP.

• OPV – Jumper to configure overvoltage protection 

(OVP) limit.

2.3

Configuration for Lithium Pack 
Chemistries

Before attaching the lithium battery pack, please insure
that jumpers OVP and V

IN

 are properly configured for

the maximum pack voltage. Attach the battery pack to
the JBat connector by attaching the top of the pack
(positive) to the left most pin (looking into the connec-
tor) and the bottom of the pack (negative) to the right
most pin.

2.4

Configuration for Nickel Pack 
Chemistries

Rechargeable nickel based battery packs can be
attached to the PS2070. Before attaching battery cells,
please insure that jumpers OVP and V

IN

 are properly

configured for the maximum pack voltage. Attach the
battery pack to the JBat connector by attaching the top
of the pack (positive) to the left most pin (looking into
the connector) and the bottom of the pack (negative) to
the right most pin.

Configuration for Lead Acid 
Chemistries

Lead acid configuration will be updated when firmware
is available.

FUNCTIONAL DESCRIPTION

3.1

PS2070 Switch Mode Charger 
Evaluation

The Switch Mode Charger Evaluation Board includes a
simple buck topology charger using the PS200 IC. The
PS200 monitors the battery to determine its status. The
control is a dual loop design with hardware based
current feedback control and firmware based voltage
feedback control. The hardware is configured as a
constant current loop, controlling the Pulse-Width
Modulator (PWM). The firmware sets the current level by
adjusting the PWM signal at PS200 pin 5 (CTRL

OUT

).

The firmware also measures the voltage and dynami-
cally adjusts the current to maintain the fully charged
constant voltage value. Please refer to the “PS200 Data
Sheet”
 for details on configuring the PS200.

Overvoltage protection – the PS200 provides
overcharge protection. This circuit can be disabled by
leaving all OVP jumper positions open. JP18 should
still be connected.
