ZHHXDZ DRV8872DDARQ1-HX

The DRV8872DDARQ1-HX is a high-performance motor driver featuring an integrated H-bridge design capable of effectively driving brushed DC motors. The device determines the maximum operating current by setting a current sense resistor on the ISEN pin. When the voltage on the ISEN pin reaches the built-in threshold of 0.35V, the current regulation function is triggered, significantly limiting the large currents generated under startup and stall conditions. The peak output current reaches 4A, while the RMS current is 2A (the specific values depend on PCB thermal dissipation). In addition, the device features a low-power sleep mode that achieves ultra-low quiescent current consumption by shutting down internal circuitry. Internal protection features include UVLO, overcurrent protection, and overtemperature protection. When a fault occurs, the nFAULT output is pulled low to report the fault. Once the fault is cleared, the device automatically returns to normal operation.
