MC33198 : High Side TMOS Driver - PWM

The MC33198D is a high side TMOS driver, dedicated for 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 MOSFET. The device has CMOS compatible input control, charge pump to drive the MOSFET gate, fault detection circuitry based on programmable Vds monitoring to detect shorted load. 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 in both on and off MOSFET state. The device uses few external components and offers an economical solution to large current high side switch. It also has PWM capability up to 1kHz.
