Features: The 33981 is a high-frequency self-protected silicon 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. A dedicated parallel input is available for an external low-side control with protection features and cross-conduction management.
