... SEMICONDUCTOR Automotive High Side TMOS Driver The MC33198D is a high side TMOS driver, dedicated for automotive appli- cations 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 ...

... The charge pump is able to charge a 25nF capacitor in less than 1ms. This allows the MC33198D to have a rapid response time and to drive the external TMOS gate very quickly, allowing fast switching on of the load. The device has an internal 14V zener diode between pin 4 and 1 to clamp the Gate-to-Source voltage and protect the MOSFET gate oxyde from destruction ...

... Fault Status Both devices report the fault status to the microcontroller via pin 6. The MC33091A fault pin is not valid when pin low state, while the MC33198D fault status is valid in both low and high states of pin 7. Power Supply Both devices are powered from the battery line. Both devices have an overvoltage shutdown greater than 20V ...
