HIGH SIDE PUMP MOTOR CIRCUIT AND FAIL-SAFE CIRCUIT LOGIC METHOD THEREOF

摘要

PURPOSE: the method for high side pump motor fail-safe circuit logic circuit is provided to detecting immediately and rapidly the ground terminal motor to break down and do not have drive motor. ;CONSTITUTION: the fault-proof circuit of high lateral circuit icludes pump motors. The fail-safe circuit includes the motor of voltage (1b) (1) ground terminal of these detections of ground LPF (low) (11) by filter, current of electric source LCS (low) (12), its apply low current to supply terminal (1a) motor driving instruction MCU, it is compared with the value of MCU detections, passes through ground LPF and the value of detection and passes through the short circuit grounding end of motor LCS. ;The 2011 of copyright KIPO submissions
