Single-phase BLDC pre-driver in a 16-LSSOP
The BD61251FV-E2: The BD61251FV- is a ROHM single-phase full-wave BLDC motor controller pre-driver in a 16-LSSOP package (4.40 mm width). It integrates commutation logic and direction management with a PWM interface, so an external MCU can set speed and torque via a single PWM line. The output stage is a pre-driver configured as two half-bridges, meaning it drives external N-channel Power MOSFETs — the 10 mA output current is the gate drive, not the motor current. The load voltage ceiling is 18 V, and the controller logic runs from 4.5 V to 16 V. Operating temperature spans -40°C to 105°C, which covers industrial enclosures and fan-tray applications without active cooling. The part is surface-mount and ships on Tape & Reel or Cut Tape — the reel option keeps kitting for high-volume pick-and-place lines.
The supplier device package is listed as 16-SSOP-B, which is the same mechanical outline as the 16-LSSOP — confirm the land pattern matches your existing SSOP-16 footprint.
