High-Side TMOS Driver
The MC33091A is a High–Side TMOS Driver designed for use in harsh automotive switching applications requiring the capability of handling high voltages attributed to load and field dump transients, as well as reverse and double battery conditions. Few external components are required to drive a wide variety of N–Channel TMOS devices. The MC33091A, driving an appropriate TMOS device, offers economical system solutions for high–side switching large currents. The MC33091A has CMOS compatible input control, charge pump to drive the TMOS power transistor, basic fault detection circuit, VDS monitoring circuit used to detect a shorted TMOS load, and overcurrent protection timer with associated current squaring circuitry.
