Energy efficient control circuit for solenoid actuated locking device

摘要

The present invention provides a driver circuit for energizing a solenoid actuated locking device. The circuit is adapted to include a microprocessor, a battery power supply, a boosting circuit and an energy storage circuit. The battery voltage is stepped up by the boosting circuit and the stepped up voltage is stored in the energy storage circuit. A solenoid driver circuit including a plurality of transistors arranged in an H-bridge configuration supply energy from the storage circuit to the solenoid under control of the microprocessor.
