It drives one brushed DC motor using two internal half-bridges configured as an H-bridge, delivering up to 3A continuous output current. The supply and load voltage range spans 4.5V to 36V, covering common 12V and 24V industrial rails without needing a separate regulator. A PWM interface accepts logic-level control signals for speed and direction, and the Bi-CMOS process keeps switching losses low. The junction temperature range of -40°C to 150°C TJ suits engine-bay, factory-floor, and outdoor enclosure environments where ambient heat is a given. ## 3A output — sizing the load budget The 3A continuous output rating is the headline number for BOM sizing. For a 12V brushed DC motor drawing 2A under load, this part runs with headroom. At 24V the same 3A limit applies, so a motor with 3A stall current will hit the ceiling — factor in the motor's locked-rotor current and the driver's peak capability (not listed here) when selecting. The two half-bridges each handle the full 3A, so the H-bridge total is 3A continuous, not 6A. ## Supply voltage range: 4.5V to 36V The single supply pin powers both the logic and the motor drive, simplifying the power tree. The 4.5V to 36V range means the same part works on a 5V logic rail, a 12V automotive battery (with transients), or a 24V industrial bus. No external buck or boost needed as long as the supply stays within that window. The lower end at 4.5V leaves margin for a 5V rail that droops under load. ## Package and thermal management The 12-WFDFN with exposed pad (3x3 mm) is the only package option. The exposed pad must be soldered to a PCB copper plane for thermal dissipation — without it, the junction temperature rises quickly above 3A continuous. The -40°C to 150°C TJ rating means the die can run hot, but the board layout determines whether it actually stays within that limit. ## Lifecycle and compliance ROHS3 compliant, so it passes EU material restrictions without exemption paperwork. For a BOM line, this means no immediate obsolescence risk and standard lead times through franchised distribution.","metaTitle":"MAX14870ETC+T Brushed DC Motor Driver, 3A, 4.5V-36V","metaDescription":"MAX14870ETC+T is a fully integrated brushed DC motor driver with 3A output, 4.5V-36V supply range, PWM interface, in a 12-TDFN package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Driver - Fully Integrated, Control and Power Stage","Interface":"PWM","Technology":"Bi-CMOS","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"12-WFDFN Exposed Pad","Voltage - Load":"4.5V ~ 36V","lifecycle_stage":"eol_hot","Current - Output":"3A","Voltage - Supply":"4.5V ~ 36V","Motor Type - AC, DC":"Brushed DC","Output Configuration":"Half Bridge (2)","Operating Temperature":"-40°C ~ 150°C (TJ)","Supplier Device Package":"12-TDFN (3x3)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.69","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.69000","currency":"USD"},{"qty":10,"price":"$4.21600","currency":"USD"},{"qty":25,"price":"$3.98520","currency":"USD"},{"qty":100,"price":"$3.45390","currency":"USD"},{"qty":250,"price":"$3.27680","currency":"USD"},{"qty":500,"price":"$2.94026","currency":"USD"},{"qty":1000,"price":"$2.47973","currency":"USD"},{"qty":2500,"price":"$2.35574","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX14870-MAX14872.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the output current of MAX14870ETC+T?","answer":"The continuous output current rating is 3A.
