The output stage uses four half-bridge Power MOSFETs, so the conduction losses are dominated by the MOSFET Rds(on) rather than a Darlington or bipolar H-bridge — this keeps the thermal rise lower at the same current for a given board copper area. ## Step resolution and interface Step resolution is selectable via the parallel interface: full-step, half-step, and quarter-step (1/4) microstepping are supported. The parallel control bus accepts step and direction signals directly from a host MCU or motion controller without needing an external sequencer. The motor supply (VM) is separate, 10 V to 47 V, so the driver can run from a regulated 5 V logic supply while the motor sees a higher, possibly unregulated, power bus. ## Package and thermal management Without it, the 2 A output current will push the junction temperature above the 150 °C absolute maximum under sustained load. Operating junction temperature range is -20 °C to 150 °C — the lower end is tight for outdoor or cold-storage equipment; if the ambient drops below -20 °C, the driver may not start reliably. The upper limit is typical for a power device; derate output current above 85 °C ambient per the datasheet's thermal derating curve. ## Lifecycle and compliance Availability and current pricing confirmed at RFQ time.","metaTitle":"Toshiba TB67S261FTG,EL Stepper Driver, 2A, 48-WQFN","metaDescription":"Toshiba TB67S261FTG,EL bipolar stepper motor driver, 2A output, 10-47V load, Parallel interface, 48-WQFN.

The key difference is step resolution: the TB67S269 supports 1/32 microstepping, while the TB67S261 stops at 1/4. If your motion profile needs finer microstepping for low-speed smoothness, the TB67S269 is the better fit. For coarser step applications, the TB67S261 is functionally equivalent and drops into the same footprint."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/toshiba/TB67S261FTG~6EL","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/toshiba/TB67S261FTG~6EL when reusing this data.
