Overview

Description

BD3812F‑E2 is a dedicated LED driver IC used for constant‑current regulation in LED backlighting and high‑brightness LED applications. It typically works as a buck (step‑down) regulator that drives an LED string from a higher supply, using an external inductor and diode. The device regulates LED current via a sense resistor and supports dimming (PWM or DC) plus protections such as overcurrent, overvoltage, and thermal shutdown. It comes in a compact surface‑mount package for easy PCB integration. Common applications include LCD TV/monitor backlights, signage, and portable illumination. For exact electrical specs (input range, reference current, dimming options, protection thresholds), refer to the manufacturer’s datasheet.

Equivalent

BD3812F-E2 is a Rohm device; there isn’t a universal direct equivalent. Equivalents depend on its function (LED driver, regulator, op-amp, etc.) and package. Please provide: (1) device function and key specs, (2) package/pin count, (3) target region. With that, I can propose specific cross-reference candidates from Rohm and other vendors.

Pinout

Pin count: 8 pins (SOP-8 package).
Function: Dual-channel constant-current LED driver (two LED driver channels with enable/shutdown capability).

Manufacturer

The BD3812F-E2 is manufactured by ROHM Co., Ltd. (ROHM Semiconductor). ROHM is a Japanese semiconductor company that designs, develops and manufactures analog and power integrated circuits, discrete semiconductors (transistors, diodes), optoelectronics and modules for automotive, industrial, communications and consumer electronics markets.

Application

BD3812F-E2 is a multi‑channel constant‑current LED driver IC. Typical applications include:
- LCD TV/monitor backlighting
- LED lighting fixtures (bulbs, tubes, panels)
- Automotive lighting and instrument panels
- Signage and backlit displays
- Portable/embedded LED illumination requiring compact, efficient CC drive
