PI2211-EVAL1: 12V/10A Cool-Swap™ Controller Evaluation Board

User Guide

The PI2211 EVAL1 evaluation board is designed to acquaint

the user to the features and benefits of Picor's PI2211 Cool-

Swap™ controller; featuring True-SOA™ MOSFET power

monitoring and protection, and Glitch-Catcher™ voltage

suppression circuitry. The PI2211 EVAL1 board is designed for

a 12V nominal BUS voltage, with an operational BUS range of

11V to 13V. It is designed to be run at 10A continuously with

a circuit breaker threshold of 13A and a start-up current limit

of 6.25A.

The evaluation board features screw-type terminal blocks to

allow for easy connections to a supply and a load. Key signal

nodes are brought out to turret pins; such as power-good,

under-voltage/enable and over-voltage. These pins can be

used for monitoring or for connection to external control

circuitry.

The PI2211 EVAL1 evaluation board is not designed, nor is it

intended, to be used as a component in an end-product.

Please refer to the PI2211 datasheet for detailed functional

descriptions, characteristics and specifications.
