» Product Change Notification
The NCV7721 is a fully protected Dual Half-Bridge Driver designed specifically for automotive and industrial motion control applications. The two half-bridge drivers have independent control. This allows for high side, low side, and H-Bridge control. H-Bridge control provides forward, reverse, brake, and high impedance states. The drivers are controlled via logic level inputs.
Features   Benefits
     
  • Ultra Low Quiescent Current in Sleep Mode
 
  • Meets low current requirements in automotive modules to prevent battery drain.
  • Power Supply Voltage Operation Down to 5 V
 
  • Operation is maintained during automotive cranking.
  • 2 High-Side and 2 Low-Side Drivers Connected as Half-Bridges
 
  • Capable of running 1 motors
  • Internal Free-Wheeling Diodes
 
  • Protects the device from excessive voltages when driving inductive loads
  • 0.5 A Continuous (1 A peak) Current
 
  • Ideal for running automotive side-view mirrors
