Texas Instruments DRV8212P H-Bridge Motor Driver
Texas Instruments DRV8212P 12V, 3A H-Bridge Motor Driver provides PWM control with low power sleep mode, optimized for systems with lower current requirements. The DRV8212P Motor Driver is integrated with four N-channel power FETs, a charge pump regulator, and protection circuitry. The triple charge pump architecture allows the device to operate down to 1.65V to accommodate 1.8V supply rails and low-battery conditions. The charge pump integrates all capacitors to reduce the overall solution size of the motor driver on a PCB and allows for 100% duty cycle operation.The TI DRV8212P supports an industry-standard PWM (IN1/IN2) control interface. The nSLEEP pin controls a low-power sleep mode which achieves ultra-low quiescent current draw by disabling the internal circuitry. The device supplies up to 4A peak output current and operates with a supply voltage from 1.65V to 5.5V.
Robust internal protection features are available on the DRV8212P, including supply under-voltage lockout (UVLO), output overcurrent (OCP), and device overtemperature (TSD).
The DRV8212P is part of a family of devices that come in pin-to-pin scalable RDS(on) and supply voltage options to support various loads and supply rails with minimal design changes. This family of devices includes DRV8210, DRV8210P, DRV8212, DRV8212P, and DRV8220.
