LOW POWER SOLENOID DRIVE CIRCUIT

Application 966/DEL/2005 published 2006-11-10, filed 2005-04-15
The present invention provides a system and method for controlling a solenoid that ensures accurate timing between the enabling of the driving circuit and the activation of the solenoid, while simultaneously providing a two energy level driving scheme to reduce power consumption. The present invention utilizes a single enable signal and supplies the solenoid two different energy levels, a higher set level and a lower hold level. The generation of these two levels is based on the enabling signal and guarantees that the higher set level is present when the solenoid is activated, thereby minimizing undesirable timing jitter.
