BD9611MUV-E2

BD9611MUV-E2 is a ROHM Semiconductor motor-driver IC designed to drive brushless DC (BLDC) or similar motors in compact applications (fans, printers, small robotics, consumer electronics). It combines the motor drive bridge and control logic in a single package, enabling easy MCU interfacing via simple input or PWM signals.
Key points:
- Purpose: efficient, compact motor drive for BLDC/stepper-type loads.
- Features: adjustable current regulation, PWM control, and comprehensive protections (e.g., undervoltage, overcurrent/overtemperature, fault reporting). It supports typical commutation schemes (sensorless or with Hall sensors) as per datasheet.
- Package/variant: “MUV” family, with the “-E2” variant indicating a specific package/revision and evaluation/production version.
- Typical usage: connect motor windings to the device’s output bridges, set the desired current with external components, control with MCU signals, and rely on built-in protections for safe operation.
Note: For exact electrical specs, pinout, recommended PCB layout, and application notes, consult the ROHM BD9611MUV-E2 datasheet and evaluation-board documentation.

28 pins. Function: ROHM BD9611MUV-E2 is a dual-channel Class-D audio power amplifier with integrated speaker protection and an I2C-compatible (digital) control interface.

- Manufacturer: ROHM Semiconductor (ROHM Co., Ltd.)
- What kind of company: A Japanese multinational maker of semiconductors and electronic components, designing and selling ICs, power devices, discretes, LEDs, sensors, and related products for automotive, consumer, and industrial markets.

BD9611MUV-E2 uses ROHM’s MUV package, a QFN-stylePb-free package.
