FAB REQUALIFICATION
The 33981 is a high frequency, self-protected 4.0 mΩ 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.
This product is undergoing a fab migration and device qualification is not complete. PC samples are available now. For more information contact your local sales office.
