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

TECHNICAL DATA

detection circuit, V

monitoring circuit used to detect a shorted TMOS load,

and overcurrent protection timer with associated current squaring circuitry.

Short circuit protection is made possible by having a unique V voltage

to current converter drive an externally programmable integrator circuit. This

circuit affords fast detection of a shorted load while allowing difficult loads,

such as lamps having high in–rush currents, additional time to turn on.

The Fault output is comprised of an open collector NPN transistor

requiring a single pull–up resistor for operation. A fault is reported whenever

the MOSFET on–current exceeds an externally programmed set level.

The MC33091A is available in the plastic 8–Pin DIP package as well as

the plastic 8–Pin surface mount package.
