The 33981 is a high frequency, self-protected 4.0 m RDS(ON) high

side switch used to replace electromechanical relays, fuses, and

discrete devices in power management applications.

The 33981 can be controlled by pulse-width modulation (PWM) with

a frequency up to 60 kHz. It is designed for harsh environments, and it

includes self-recovery features. The 33981 is suitable for loads with high

inrush current, as well as motors and all types of resistive and inductive

loads.

The 33981 is packaged in a 12 x 12 mm non-leaded power-enhanced

PQFN package with exposed tabs.
