NCV7703B Triple Half-Bridge Driver with SPI Control The NCV7703B is a fully protected Triple HalfBridge Driver designed specifically for automotive and industrial motion control applications. The three halfbridge drivers have independent control. This allows for high side, low side, and HBridge control. HBridge www.onsemi.com control provides forward, reverse, brake, and high impedance states. The drivers are controlled via a standard Serial Peripheral Interface MARKING (SPI). This device is fully compatible with ONSemiconductors DIAGRAM NCV7708 Double Hex Driver. 14 Features SOIC14 NCV7703BG Ultra Low Quiescent Current in Sleep Mode, 1 A for V and V 14 D2 SUFFIX S CC AWLYWW CASE 751A 1 Power Supply Voltage Operation down to 5 V 1 3 HighSide and 3 LowSide Drivers Connected as HalfBridges Internal FreeWheeling Diodes NCV7703B = Specific Device Code A = Assembly Location Configurable as HBridge Drivers WL = Wafer Lot 0.5 A Continuous (1 A peak) Current Y = Year WW = Work Week R = 0.8 (typ) DS(on) G = PbFree Package 5 MHz SPI Control with Daisy Chain Capability Compliance with 5 V and 3.3 V Systems Overvoltage and Undervoltage Lockout PIN CONNECTIONS Fault Reporting GND GND 1.4 A Overcurrent Threshold Detection with Optional Shutdown OUT3 OUT1 V OUT2 S 3 A Current Limit with Auto Shutdown CSB V CC Overtemperature Warning and Protection Levels SI EN Internally Fused Leads in SOIC14 Package for Better Thermal SCLK SO GND GND Performance ESD Protection up to 6 kV These are PbFree Devices ORDERING INFORMATION Typical Applications Device Package Shipping Automotive NCV7703BD2G 55 Units / Rail SOIC14 Industrial (PbFree) DC Motor Management NCV7703BD2R2G 2500 / SOIC14 V V V S S S Tape & Reel (PbFree) For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specifications Brochure, BRD8011/D.
