NCV7701 2.0 Amp H-Bridge Driver This automotive grade H-Bridge driver provides a flexible means for controlling loads requiring bidirectional drive currents. Bridge outputs are protected from overcurrent at each switch and overtemperature shutdown provides product robustness. The NCV7701 inputs can be interfaced to a range of voltages, including vehicle battery voltage. The product features a low quiescent current mode, allowing unswitched connection to the power source. The NCV7701 is produced using ON Semiconductor's POWERSENSEt BCD technology. http://onsemi.com MARKING DIAGRAM Features 20 •Forward, Reverse, Brake High, Brake Low Modes •1.0 A Output Current Capability (DC) •Supply Voltage Range 7.0 V to 26 V •0.25 W RDS(ON) per Driver @ 25°C •Sleep Mode (IQ < 10 mA) •Overvoltage Protection •Thermal Protection •Undervoltage Disable Function •Short Circuit Protection •Cross Conduction Protection •Synchronous Low-Side Rectification for Lower Power Dissipation •Diagnostic Output (Open Drain) •TTL/CMOS/Pullup to Battery Compatible Inputs •20 Lead SO Package with 8 Internally Fused Leads •AEC Qualified •PPAP Capable •These are Pb-Free Devices* Typical Applications •DC Motors •Stepper Motors •Modulator Valves 1 SOIC-20 WB CASE 751D DW SUFFIX NCV7701 AWLYYWWG 1 A WL YY WW G = Assembly Location = Wafer Lot = Year = Work Week = Pb-Free Package PIN CONNECTIONS 1 20 VBAT NC OUTB GND GND GND GND FAULT NC NC NC NC OUTA GND GND GND GND EN IN1 IN2 ORDERING INFORMATION Device NCV7701DWG Package SOIC-20W (Pb-Free) Shipping† 38 Units/Rail NCV7701DWR2G SOIC-20W 1000 Tape & Reel (Pb-Free) †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. *For additional information on our Pb-Free strategy and soldering details, please download the ON Semiconductor Soldering and Mounting Techniques Reference Manual, SOLDERRM/D. © Semiconductor Components Industries, LLC, 2007 November, 2007 - Rev. 7 1 Publication Order Number: NCV7701/D NCV7701 VBAT EN Voltage Reference 200 kHz Oscillator Charge Pumps ILIM ILIM M1 M3 IN1 Bridge Control OUTB Gate Drive OUTA IN2 M2 M4 Fault Detection FAULT • TSD • OVSD • UVLO Masking Timer ILIM ILIM GND Figure 1.

When the undervoltage lockout threshold is exceeded, the outputs will reflect the input states. Outputs change to HI-Z whenever an undervoltage, overvoltage or thermal shutdown fault is detected. Normal operation will resume when faults are resolved. Overcurrent Protection Current is monitored continuously in each switch of each half bridge when the ENA input is in a high state thus protecting each switch from faults due to short to GND, short to VBAT or shorted load conditions. Only the affected half-bridge is disabled for short to VBAT or short to GND faults. A mask timer is initiated after a fault is detected and prevents recognition of an overcurrent event until the mask time expires. Persistence of an overcurrent condition causes the bridge output to change to HI-Z and the FAULT output to latch low until the next transition occurs on either the input related to the faulted output or the ENA input is brought low then high again. This method of protection provides current limiting on a cycle-by-cycle basis and helps allow a stall torque current to be ignored during motor start. Continued overcurrent may eventually result in activation of the thermal shutdown circuitry, thus activating a second level of protection for the NCV7701.
