Document Number: MC33981 Rev. 6.0, 5/2007
Single High-Side Switch (4.0 mΩ), PWM clock up to 60kHz
The 33981 is a high-frequency, self-protected 4.0 mΩ RDS(ON) highside 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 in-rush current, as well as motors and all types of resistive and inductive loads. The 33981 is packaged in a 12 x 12 non-leaded power-enhanced Power QFN package with exposed tabs. Features • Single 4.
