Order this document by MC33293A/D MC33293A Advance Information Quad Low Side Switch 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. The MC33293A is parametrically specified over – 40°C ≤ TA ≤ 125°C ambient temperature and a 9.0 V ≤ VPWR ≤ 14.5 V supply.
