LED Driver IC datasheet and documents for MP3326GR-Z

MP3326GR-Z

LED Driver IC Overview

The MP3326GR-Z is a 16-channel white LED driver IC from Monolithic Power Systems, designed for general lighting and backlight applications. It operates within a wide input voltage range of 4V to 16V and provides 50mA per channel. The device features separated PWM and analog dimming capabilities controlled via an I2C interface. Packaged in a 24-QFN (4x4) format, it supports surface-mount installation and functions reliably across a temperature range of -40°C to +150°C junction temperature.

LED Driver IC Feature Summary

Integrates 16 internal current sources for independent channel control
Supports separated PWM and analog dimming methods
Includes LED open-load protection and short protection with configurable thresholds
Features under-voltage lockout and overtemperature protection mechanisms

LED Driver IC Applications

General lighting systems
Backlight illumination
White LED arrays

LED Driver IC Procurement Notes

Verify the specific suffix against official MPS documentation to confirm package type and environmental compliance status. Ensure the design accommodates the 24-QFN thermal requirements and I2C bus constraints. Confirm that the selected variant matches the required operating temperature range and dimming specifications for the target application environment.

LED Driver IC Selection Notes

Select this component when a high-channel-count linear LED driver is required for uniform brightness control. The integrated I2C interface simplifies system architecture by reducing pin count compared to parallel control schemes. Consider the thermal dissipation characteristics of the QFN package and the 50mA per channel limit when designing the PCB layout and heat sinking strategy for the intended load configuration.

LED Driver IC Part Context

This part belongs to the MP3326 series of LED drivers manufactured by Monolithic Power Systems. It is distinct from other MPS products like the MP6532 motor pre-driver or the MP3331 camera flash driver due to its specific multi-channel linear topology and I2C control interface tailored for static lighting applications rather than motor control or high-current boost conversion.
