Step resolution is selectable between full-step, half-step, and quarter-step — the 1/4 microstep mode reduces low-speed torque ripple and audible noise in applications like desktop printers or medical pumps. Four half-bridge outputs drive the two bipolar stepper windings.","metaTitle":"ROHM BD6385EFV-E2 Stepper Motor Driver, 1.2A, 40-HTSSOP","metaDescription":"BD6385EFV-E2 from ROHM Semiconductor: fully integrated bipolar stepper motor driver, 1.2A output, 10-28V supply, parallel interface, DMOS, active production","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Driver - Fully Integrated, Control and Power Stage","Interface":"Parallel","Technology":"DMOS","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"40-VSSOP (0.213\\\", 5.40mm Width) Exposed Pad","Voltage - Load":"10V ~ 28V","Step Resolution":"1, 1/2, 1/4","lifecycle_stage":"eol_hot","Current - Output":"1.2A","Voltage - Supply":"10V ~ 28V","Motor Type - AC, DC":"Brushed DC","Motor Type - Stepper":"Bipolar","Output Configuration":"Half Bridge (4)","Operating Temperature":"-25°C ~ 150°C (TJ)","Supplier Device Package":"40-HTSSOP-B"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.33","priceTiers":[{"qty":1,"price":"$8.33000","currency":"USD"},{"qty":10,"price":"$7.52100","currency":"USD"},{"qty":25,"price":"$7.17080","currency":"USD"},{"qty":100,"price":"$6.22640","currency":"USD"},{"qty":250,"price":"$5.94660","currency":"USD"},{"qty":500,"price":"$5.42190","currency":"USD"},{"qty":1000,"price":"$4.95000","currency":"USD"},{"qty":2000,"price":"$4.95000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4080434e5ea36920ee2359a585e94bd8.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BD6385EFV-E2/alternatives.json"},"ai":{"faq":[{"question":"What is the output current rating of the BD6385EFV-?","answer":"The BD6385EFV- is rated for a continuous output current of 1.2 A per phase.
