E525.07 is a control IC for up to 4 high-side power-NMOS typically driving glow plugs in Diesel engines. The load current is varied by PWM duty cycle modulation at the power- NMOS gates according to the requirements determined by an engine management unit. Advanced control and diagnosis features such as load current monitoring, battery-, supply-, and charge pump- voltage and temperature supervision are included. The load current is measured via the drain-source voltage drop at the power- NMOS transistors. Ground voltage sensing at the glow plugs to compensate for ground shifts is included also. For communication with the engine control unit either a 2-wire PWM interface which can be operated in two modes (Standard or Advanced) is used, or a SPI communication interface for a micro processor is available.
