Principio de funcionamiento
Four N-channel MOSFETs form an H-bridge with 500 mOhm total RDS(ON). PHASE/ENABLE inputs control motor direction and braking. IN1/IN2 mode allows independent half-bridge control for custom drive patterns. VPROPI output provides proportional current sense for closed-loop control. OCP uses VDS sensing with auto-retry.
Aplicaciones
- Brushed DC motor drive
- Valve / solenoid control
- Industrial 24V motor
- Lock / actuator driver
