Single High Side Switch (4.0 mOhm), PWM clock up to 60 kHz
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.
Features
• Single 4.0 m RDS(ON) maximum high side switch
• PWM capability up to 60 kHz with duty cycle from 5 % to 100 %
• Very low standby current
• Slew-rate control with external capacitor
• Over-current and over-temperature protection, under-voltage
shutdown, and fault reporting
• Reverse battery protection
• Gate drive signal for external low side N-channel MOSFET with
protection features
• Output current monitoring
• Temperature feedback
