It drives one bipolar stepper motor at up to 1.5 A per winding from an 8 V to 32 V supply rail, with selectable microstepping down to 1/8 step. The eight half-bridge outputs are built around Power MOSFETs, so no external FETs or charge-pump components are needed — just the motor, a supply, and logic-level step/direction signals. This part is rated for general-purpose industrial motion control and carries a junction temperature range of -40°C to 150°C, which covers most factory-floor and outdoor equipment enclosures. ## 1.5 A output — what it means for motor sizing The 1.5 A continuous per-bridge rating decides whether this driver can handle your motor. ## Lifecycle and compliance The DRV8821DCA is listed as Active with ROHS3 compliance. The ROHS3 status covers the full substance restriction list, which simplifies compliance documentation for EU-market equipment.","metaTitle":"DRV8821DCA Bipolar Stepper Driver, 1.5 A, 8-32 V, 48-HTSSOP","metaDescription":"TI DRV8821DCA bipolar stepper motor driver with integrated power MOSFETs, 1.5 A output, 8-32 V supply, 1/8 microstep, -40 to 150°C.

The DRV8821DCA uses eight half-bridges in a 48-HTSSOP and tops out at 1/8 step. The DRV8825 is not a pin-compatible swap — the package and pinout differ."},{"question":"What is the thermal resistance of DRV8821DCA?","answer":"The evidence does not provide a specific thermal resistance value (RθJA or RθJC). For thermal design, rely on the exposed pad of the 48-HTSSOP and follow the PCB layout guidelines in the datasheet to keep the junction temperature within the -40°C to 150°C range."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/DRV8821DCA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/DRV8821DCA when reusing this data.
