The DRV8706SQRHBRQ1 is an automotive-qualified 40V H-bridge smart gate driver from Texas Instruments, featuring an integrated wide common-mode inline current sense amplifier and comprehensive offline diagnostics capabilities in a compact 32-pin VQFN package. Operating from 4.9V to 37V with a 40V absolute maximum rating, this device drives high-side and low-side N-channel power MOSFETs using an integrated doubler charge pump for the high side and a linear regulator for the low side, enabling 100% PWM duty cycle operation. Featuring functional safety capability, smart gate drive architecture with adjustable current control, and an extensive protection suite, this driver targets mission-critical automotive motor applications.
The DRV8706SQRHBRQ1 targets automotive brushed DC motor applications where robust control and comprehensive diagnostics are essential. Primary applications include power window lift and sliding door mechanisms, power sunroof control, power seat modules, power trunk and lift gate actuation, and windshield wiper systems. The device excels in brushed DC fuel, water, and oil pump control across 12V and 24V vehicle electrical systems. Additional applications include solenoid and relay drivers, HVAC blower motors, mirror positioning, and off-highway vehicle motor control. The functional safety capability makes it particularly suitable for safety-relevant motor applications including throttle actuation and chassis control systems where fault detection and diagnostic reporting are mandatory.
FAQ
Q: How does the inline current sensing work?
A: The wide common-mode amplifier measures motor current through a shunt resistor placed in-line with the motor winding, continuously sensing current even during recirculation windows.
Q: What diagnostics are available offline?
A: Open load detection and short circuit diagnostics operate even when the motor is not actively driven, enabling fault detection during startup or standby.
Alternative Motor Driver Models
● DRV8714SPTRQ1 (Texas Instruments): A four-channel half-bridge smart gate driver with two inline current sense amplifiers for multi-motor applications in a larger PowerPAD package.
● DRV8718SPJRQ1 (Texas Instruments): An eight-channel half-bridge smart gate driver with dual inline current sense amplifiers for systems driving multiple brushed DC motors or multiple solenoids.
● DRV8701HRPHR (Texas Instruments): A non-automotive H-bridge gate driver with similar smart gate drive architecture for industrial motor applications not requiring AEC-Q100 qualification.
