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
HIGH-SIDE TMOS DRIVER
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.
