Product Overview
The DRV8870 is a Texas Instruments brushed DC motor driver classified under Power_Management. Its H-bridge power stage drives one DC motor, one winding of a stepper motor, or other loads, with forward, reverse, brake, and coast states controlled by IN1 and IN2 logic inputs.
The recommended motor supply range is 6.5 to 45 V, while the VM absolute maximum rating is -0.3 to 50 V. The driver has 565 mOhm typical total on-resistance, made from a 307 mOhm typical high-side FET and a 258 mOhm typical low-side FET under the stated 24 V, 1 A, 25 kHz, 25°C test condition.
Control and protection functions include 0 to 200 kHz logic input PWM capability, 0 to 100 kHz motor speed PWM operation, VREF-based current regulation with 10 V/V typical ISEN gain, 25 us typical off-time, and 2 us typical blanking time. The device also specifies undervoltage lockout, overcurrent retry, thermal shutdown, sleep mode, ESD ratings, and package thermal metrics for the 8-pin HSOP PowerPAD DDA package.

Procurement Notes
When requesting a quote for DRV8870, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For power IC and power device sourcing, voltage rating, current rating, power dissipation, package thermal performance, protection features, qualification grade and application conditions should be reviewed before approval.
FAQ
What motor topology does the DRV8870 use?
The DRV8870 uses an H-bridge brushed DC motor driver topology. The extracted datasheet facts state that it can drive one DC motor, one winding of a stepper motor, or other loads.
What supply voltage range is recommended for DRV8870 VM?
The recommended VM operating supply range is 6.5 to 45 V. The absolute maximum VM rating is -0.3 to 50 V over the operating free-air temperature range.
How are forward, reverse, brake, and coast controlled?
IN1=1 and IN2=0 drives forward with OUT1 high and OUT2 low. IN1=0 and IN2=1 drives reverse. IN1=1 and IN2=1 brakes with both outputs low, while IN1=0 and IN2=0 disables both outputs to high-Z.
