It handles brushed DC motors and unipolar stepper motors, accepting a PWM interface from a microcontroller or motion controller. The load voltage range spans 6.5 V to 45 V. ## 3.6 A continuous output — sizing the load The 3.6 A continuous output current sets the practical motor size this driver can handle. The PowerPad package is designed to pull heat into the PCB copper plane. ## Supply and logic voltage — separate rails The logic supply (VDD) runs from 0 V to 5.5 V. The load supply (VM) is the 6.5 V to 45 V rail that powers the motor. ## Package and mounting — 8-PowerSOIC with PowerPad The DRV8870DDA comes in an 8-PowerSOIC package with a 3.90 mm body width and a PowerPad on the underside. It is a surface-mount part, shipped in Tube form. The PowerPad is the primary thermal path; the PCB footprint should include a copper pad and at least four thermal vias to the ground plane. The supplier device package is listed as 8-SO PowerPad, which is the same physical outline. ## Lifecycle and compliance — active, no obsolescence concern There is no last-time-buy notice or end-of-life announcement. For new designs, this part carries no supply-risk flag.","metaTitle":"DRV8870DDA motor driver, 6.5V–45V, 3.6A, Active","metaDescription":"TI DRV8870DDA fully integrated brushed DC/stepper motor driver. 3.6A output, 6.5V–45V load, PWM interface, -40°C to 150°C.

Peak current may be higher depending on duty cycle and thermal management; the PowerPad package requires a good thermal PCB layout to sustain full current."},{"question":"What is the difference between DRV8870 and DRV8871?","answer":"The DRV8870 and DRV8871 are functionally similar integrated motor drivers from TI. The DRV8870 uses a PWM interface, while the DRV8871 adds an integrated current-sense amplifier for closed-loop current regulation. For applications needing precise current control without an external sense resistor, the DRV8871 is the better fit; for simple PWM-driven brushed DC or unipolar stepper motors, the DRV8870DDA is sufficient."},{"question":"What is the replacement or equivalent for DRV8870DDA?","answer":"The DRV8811PWPR is a functional peer from TI, but it is a different part: it has four half-bridges (bipolar stepper support), a lower load voltage (8 V typical), and a lower output current (1.9 A). It is not a pin-compatible drop-in replacement. For a direct equivalent, stay with the DRV8870DDA or consider the DRV8871 if current sensing is needed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/DRV8870DDA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/DRV8870DDA when reusing this data.
