MC33385中文资料摩托罗拉数据手册PDF规格书

The MC33385 is a Quad Low Side Driver fully protected switch. This device is a general purpose Low Side Driver but has been especially designed to operate in engine management application as injector driver or automotive gear box. It is interfaced directly with a microcontroller for parallel control of the load and the individual output

diagnostic is done through a SPI. The diagnostic logic recognizes 4 failure types at each output stage the overcurrent, the short to GND, the openload and the over-temperature.

•RDSON of 250mW per Output at 25°C

•Supplied from the main 5V Vcc

•Input CMOS Compatible

•Diagnostic through SPI

•Nominal Current of 2A per Output

•Current Limitation at 3A with Automatic Turn Off

•Output Internally Clamped at 50V typ for Inductive Load Drive

•Junction to Case Thermal Resistance of 4.4°C/W

•Individual Output over Temperature Shutdown
