PC33981

Freescale Semiconductor, Inc. MOTOROLA SEMICONDUCTOR TECHNICAL DATA Document order number: MC33981 Rev 2.0, 10/2004 Preliminary Information High-Frequency, High-Current, Self-Protected High-Side Switch (4.0 mΩ up to 60 kHz) 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 nonleaded power-enhanced Power QFN package with exposed tabs. Features Single 4.0 mΩ 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 Overcurrent and Overtemperature Protection, Undervoltage 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 33981 HIGH-SIDE SWITCH 4.0 mΩ Freescale Semiconductor, Inc...
