Hood Louver Driver Circuit Diagram using IC LM393

Sponsored Links


The following schematic shows Hood Louver Driver Circuit Diagram using IC LM393. This circuit uses an LM393 op-amp comparator (U1) to monitor the Throttle Position Sensor (TPS) voltage. As seen in the diagram, the output of the LM393 drives a high-current PNP transistor (Q2), which turns on/off the hood louver solenoid relay.
