Cool-Swap® Hot-Swap / Circuit-Breaker Controller

Not recommended for new designs.

The PI2211 is a Hot-Swap/circuit-breaker controller for bus voltages of 0.9 – 14V. Unlike conventional Hot-Swap controllers, the PI2211 incorporates True-SOA MOSFET protection which emulates the transient thermal performance of the MOSFET ensuring safe operation. Typical Hot-Swap devices utilize power limiting based upon standard SOA curves without considering transient performance issues. Only the PI2211 with True-SOA emulates and protects the MOSFET under its actual operating conditions considering transient events.
