It drives one brushed DC motor or one winding of a bipolar stepper motor using a PWM interface, with the supply and motor voltage range spanning 4.5 V to 33 V. The continuous output current rating of 3.7 A supports small-to-medium format printers, office automation, and similar motion-control loads where board space is tight. The junction temperature range of -40°C to 150°C covers industrial and under-hood automotive environments without derating at the high end. ## 3.7 A continuous output — sizing the load and thermal path The 3.7 A output current is the continuous rating per the datasheet typical column. For a brushed DC motor running at 2 A to 3 A steady-state, this part provides roughly 20% headroom before the thermal limit. The 8-PowerSOIC package with exposed PowerPad is the primary heat path — the PCB land pattern must include a thermal via array under the pad to keep the junction below 150°C at full load. At 3.7 A continuous, the copper pour area on the bottom layer should be sized for the expected dissipation; the datasheet's thermal impedance curves are the reference, not the absolute-max junction alone. ## Active lifecycle — no near-term end-of-life risk The DRV8231ADDAR carries an Active product status with ROHS3 compliance. The active status also supports new design-ins — no need to qualify a replacement mid-cycle.","metaTitle":"DRV8231ADDAR 33V H-Bridge Motor Driver, 3.7A Output","metaDescription":"TI DRV8231ADDAR fully integrated H-bridge motor driver. 4.5V–33V supply, 3.7A output, PWM interface, -40°C to 150°C.

This is the per-device limit for the H-bridge; the actual load current must also respect the package thermal limits at the operating ambient temperature."},{"question":"Is DRV8231ADDAR compatible with 5V logic?","answer":"The PWM input logic thresholds are referenced to the driver supply voltage (VCC). At VCC = 5 V, the logic-high threshold is typically 2.0 V, so a 5 V or 3.3 V MCU output can drive the input directly. At higher VCC (e.g., 24 V), the logic-high threshold scales proportionally — verify against your controller's VOH at the chosen supply voltage using the datasheet's input logic level table."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/DRV8231ADDAR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/DRV8231ADDAR when reusing this data.
