The DRV8870 from Texas Instruments is a versatile brushed DC motor driver suitable for printers, appliances, and industrial equipment. It utilizes an H-bridge configuration with four N-channel MOSFETs to control motors bidirectionally, capable of handling up to 3.6A peak current.
This device operates over a wide voltage range of 6.5V to 45V. Motor speed can be precisely controlled using pulse-width modulation (PWM) input, with selectable current-decay modes. Integrated current regulation, based on the VREF and ISEN pins, helps manage system power requirements and stability, especially during motor startup or stall conditions.
For enhanced reliability, the DRV8870 includes comprehensive protection features such as VM undervoltage lockout (UVLO), overcurrent protection (OCP), and thermal shutdown (TSD). It also supports automatic fault recovery. The driver is housed in a small 8-pin HSOP package with a PowerPAD, measuring 4.9mm x 6.0mm, making it suitable for space-constrained designs.
