DRV8873SPWPR

The DRV8873SPWPR from Texas Instruments is a versatile H-bridge motor driver IC suitable for driving brushed DC motors, stepper motor windings, or solenoid loads in industrial environments. It supports a wide operating voltage range from 4.5V to 38V and can deliver up to 10A of peak current.

This device features integrated current sensing with a current mirror output, allowing for precise monitoring of motor current. The control interface is configurable, supporting PH/EN or PWM inputs, and includes an SPI interface option for advanced control. It is designed with protection features such as undervoltage lockout (UVLO), charge pump undervoltage (CPUV), overcurrent protection (OCP), output short protection, open load detection, and thermal shutdown (TSD).

The DRV8873SPWPR is housed in a 24-pin HTSSOP PowerPAD package, enabling efficient heat dissipation. It operates across a temperature range of -40°C to 125°C. The driver supports 1.8V, 3.3V, and 5V logic inputs and includes a low-power sleep mode drawing only 10 µA.

Key electrical characteristics include a low R DS(ON) of 150 mΩ at 25°C and 250 mΩ at 150°C. The integrated half-bridge driver stage consists of N-channel MOSFETs, providing bidirectional motor control. Its compact package and robust feature set make it an ideal choice for various motor control applications.
