A Smartpower Innovative Actuator in Automotive Field

This work describes a electronic device, made by a new smartpower technology: VIPower-M2/BCD. The component is a monolithic switch self protected, it is a high side driver which can drive inductive or resistive loads with a grounded terminal. The device merges on the same chip a Powermos transistor delivering up to 25.4 with 1.2V voltage drop and 0.04¿ of R^DSON, with a logic and analog circuit in bipolar, CMOS, DMOS technology. It is protected against short circuit, over voltage, over temperature and has a diagnostic output which signals previous fault conditions and allows the communication between chip and outside world. The technology allows a supply voltage up to 60V and the implementation on one chip of functions before realized by two or more devices.
