The MC33293A is a single monolithic integrated circuit designed for quad
low side switching applications. This device was initially conceived as a quad
injector driver for use in the harsh automotive environment but is well suited
for many other applications. The MC33293A incorporates SMARTMOS
technology having CMOS logic, bipolar and CMOS analog circuitry and
DMOS power MOSFETs. All of the device inputs are CMOS compatible. The
four output devices are N-channel power MOSFETs. A Fault detect output is
provided to flag the existence of open loads (outputs ON or OFF) or shorted
loads. If a short circuit is detected, the fault detect circuitry turns off the
shorted output, but allows the others to function normally. An overvoltage
(VPWR) condition will turn off all outputs for the overvoltage duration. Each
output functions independently and has a drain-to-gate diode clamp for
inductive flyback voltage protection. A Single/Dual select pin is incorporated
to allow either individual output control or control of a pair of outputs from one
input.
