Technical Data

Automotive High-Side TMOS

Driver

33198

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 V_DSmonitoring 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.
