Cool-Swap Hot-Swap / Circuit-Breaker Controller

The PI2211 is a Hot-Swap / circuit-breaker controller for bus voltages of 0.9 to 14 V. 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 the power limiting based upon standard SOA curves not taking into account transient performance issues. Only the PI2211 with True-SOA emulates and protects the MOSFET under its actual operating conditions taking into account transient events.
