BD94121F-GE2

BD94121F-GE2 is Rohm’s BD-series motor-driver IC. It combines two high‑current MOSFETs with an on‑chip gate driver and current sensing to drive small BLDC or stepper motors directly from a microcontroller, reducing external components.
Key points:
- Two‑channel integrated driver for brushless/stepper motors; simple logic control with PWM/step-like inputs.
- Built‑in protections: overcurrent, over/undervoltage, overtemperature, and fault/diagnostic output.
- Adjustable peak current/current regulation with dead‑time to prevent shoot‑through.
- RoHS-compliant GE2 package variant; check exact pinout and package options in the datasheet.
Common applications:
- Printers, cooling fans, robotics, office automation, automotive subsystems.
Note:
For exact electrical specs, pinout, timing, and application guidelines, refer to the BD94121F-GE2 datasheet.
