DRV8212DSGR

The DRV8212DSGR from Texas Instruments is an integrated H-bridge motor driver featuring four N-channel power FETs, a charge pump regulator, and robust protection circuitry. This device is capable of driving one bidirectional brushed DC motor, two unidirectional brushed DC motors, or other loads such as solenoids and relays.

Key electrical specifications include an operating supply voltage range of 1.65-V to 11-V and high output current capability, delivering up to 4-A peak in full-bridge configuration and 8-A peak in a parallel half-bridge configuration. The MOSFET on-resistance is rated at 280 mΩ (HS + LS). It supports multiple control interfaces, including standard PWM (IN1/IN2), phase/enable (PH/EN), independent half-bridge, and parallel half-bridge modes. The device also supports 1.8-V, 3.3-V, and 5-V logic inputs.

For power efficiency and reduced GPIO usage, the DRV8212DSGR incorporates an ultra-low-power sleep mode, drawing less than 84.5 nA at specified conditions, and a timed autosleep mode. Integrated protection features include undervoltage lockout (UVLO), overcurrent protection (OCP), and thermal shutdown (TSD), ensuring reliable operation.

The DRV8212DSGR is available in an 8-WSON (2x2 mm) package and is designed for surface mount applications. Its compact size and integrated features make it suitable for various applications including water, gas, and electricity meters, IP network cameras, electronic smart locks, and robotic toys.
