MCZ33198

www.DataSheet4U.com Freescale Semiconductor Technical Data Document Number: MC33198 Rev. 2.0, 11/2006 Automotive High-Side TMOS Driver The MC33198 is a high-side TMOS driver, dedicated to automotive applications. It is used in conjunction with an external power MOSFET for high-side drive applications. The device can drive and protect a large variety of MOSFETs. The device has a CMOS compatible input control, charge pump to drive the MOSFET gate, and fault detection circuitry based on programmable VDS monitoring to detect shorted loads. It also includes a programmable timer function to eliminate undesired switch off due to in rush currents, and a status pin which reports the output status of both on and off MOSFET states. The device uses few external components and offers an economical solution to large current high side switches. It also has PWM capability up to 1kHz. 33198 HIGH-SIDE TMOS DRIVER Features Designed for Automotive High Side Driver Application Works with a Wide Variety of N-Channel Power MOSFETs ORDERING INFORMATION PWM Capability On Board Charge Pump Capable of Charging 25nF in less than 1ms Temperature Device Package with No External Components Required Range (TA) Drive Inductive Load with No External Clamp Circuitry Required MC33198D CMOS Logic Compatible Input Control -40°C to 125°C 8 SOICN MCZ33198EF/R2 TMOS Over Current and Short Circuit Protection Fault Output to Report an MOSFET Overcurrent Condition Output Status Available when MOS...
