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 s [ ... ]
