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.
