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) development 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.
