All rights reserved. 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 Figure 1. 33981 Simplified Application Diagram HIGH SIDE SWITCH 33981 ORDERING INFORMATION Device (Add R2 Suffix for Tape and Reel) Temperature Range (TA) Package MC33981BHFK -40 to 125 °C 16 PQFN MC33981ABHFK Bottom View FK (Pb-Free Suffix) 98ARL10521D 16-PIN PQFN (12 X 12) VDD I/O I/O I/O I/O A/D A/D MCU CONF FS INLS EN INHS TEMP CSNS OCLS SR GND VPWR CBOOT OUT DLS GLS VDD M VPWR 33981 |
