Overview

Description

BD9611MUV-E2 is a ROHM Semiconductor IC that acts as a high-efficiency buck regulator with integrated LED‑driver capabilities. In a compact MUV package, it enables constant‑current LED driving from a wide input voltage (well-suited for automotive/industrial rails) with minimal external parts. Core features typically include PWM dimming input, adjustable LED current, over‑current/short‑circuit protection, over‑temperature protection, and undervoltage lockout, delivering good line/load regulation and high efficiency. It’s commonly used for automotive lighting, LED backlights, and other LED/power‑supply applications requiring a protected, compact buck converter with built‑in LED drive. The E2 suffix denotes a specific ROHM grade/package variant; exact electrical specs (input range, current rating, dimming interface) are in the BD9611MUV-E2 datasheet. For design use, consult the datasheet and evaluation boards from ROHM.

Features

BD9611MUV-E2 features (concise):
- Automotive-grade LED driver IC with I2C control
- Multi-channel constant-current output drivers
- PWM/dimming control for brightness
- Open/short LED protection with fault/status reporting
- Protection: overcurrent, overvoltage, undervoltage, thermal shutdown
- Thermal warning and protection with hysteresis
- Wide input voltage range suitable for 12V automotive systems
- High efficiency with low quiescent current in standby
- Small MUV-E2 package (surface-mount) for compact assemblies
Note: For exact channel count, current limits, register map, and pinout, refer to the ROHM BD9611MUV-E2 datasheet.

Package

BD9611MUV-E2 uses ROHM’s MUV package (leadless, surface-mount). For exact dimensions and pinout, refer to the datasheet’s package section.

Pinout

- Pin count: 16 pins (SSOP/16-pin package)
- Function: Dual-channel motor driver (two half-bridges) for driving a DC motor or stepper with current regulation; includes input/control, enable, supply, ground, and sense/feedback pins.

Manufacturer

- Manufacturer: ROHM Semiconductor (ROHM Co., Ltd.)
- What kind of company: A Japanese multinational semiconductor and electronic components company that designs and manufactures ICs, discretes, LEDs, power devices, and other components for automotive, consumer, and industrial markets.

Application

BD9611MUV-E2 is a ROHM power-management IC. Typical application areas include:
- Automotive electronics (DC-DC conversion, power distribution, load switching)
- LED lighting drivers
- Small motor drivers (DC/stepper)
- General power-management in consumer electronics
Refer to the datasheet for exact features, operating conditions, and pinout to confirm suitability.

Equivalent

I can’t provide exact equivalents without knowing the device type. BD9611MUV-E2 could be a DC-DC converter, LED driver, motor driver, etc. Please share the datasheet or confirm its function (and key specs: voltage, current, package). Then I’ll give cross-reference parts from TI, ST, Onsemi, NXP, etc., with similar specs.
