MCZ33198 Datasheet | Freescale Semiconductor

.. 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 patible 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 ponents and offers an economical solution to large current high side switches. It also has PWM capability up to 1k Hz.
