BD7844AEFV-E2

Overview

The BD7844AEFV-E2 is a 16-channel, 8-bit PWM LED driver manufactured by ROHM Semiconductor. It features linear dimming capability with an output current of 80mA per channel and a low-level output current of 30mA. The device utilizes an I2C-compatible and 2-wire serial interface for control. It is housed in a 28-HTSSOP-B package and is designed for applications requiring precise LED brightness control.

Feature Summary

Supports 16-channel independent linear dimming control
Integrates I2C-compatible and 2-wire serial communication interfaces
Provides 8-bit PWM resolution for precise brightness adjustment

Applications

LED backlighting systems
Display brightness control modules
General illumination lighting controllers

Procurement Notes

Verify the specific suffix 'E2' to confirm the tape and reel packaging configuration. Ensure compatibility with the host controller's I2C or 2-wire serial protocol voltage levels. Check moisture sensitivity labels as the component is humidity sensitive. Confirm the HTSSOP-B-28 footprint matches the PCB design requirements before finalizing procurement.

Selection Notes

Select this component when a high channel count (16) is required for uniform LED array driving. The linear dimming feature makes it suitable for applications where flicker-free performance at low brightness levels is critical. Consider the 80mA output current limit when sizing the LED load. The integrated serial interface reduces pin count compared to parallel control solutions.

Part Context

This part belongs to ROHM's LED driver portfolio, specifically designed for multi-channel lighting applications. The BD7844 series focuses on simplifying system design by integrating control logic and power drivers into a single compact package. It complements other ROHM PMIC solutions for comprehensive power management in electronic devices.

Replacement Considerations

The BD7844AEFV-LB is a documented variant within the same family. Verify if the functional specifications and pinout are identical before substitution. No other public substitute part numbers are confirmed in available documentation.
