MIC2846A-PPYMT-TR

LED Driver IC Overview

The MIC2846A-PPYMT-TR is a high-efficiency White LED driver featuring six linear channels and two integrated low-quiescent current LDOs. Designed for digital control, it drives up to six LEDs with a maximum output current of 20mA per channel. The device operates on a supply voltage range of 3V to 5.5V and supports PWM dimming. It is housed in a compact 14-TMLF (2.5x2.5mm) package and functions within a junction temperature range of -40°C to +125°C.

LED Driver IC Feature Summary

• Integrates six linear WLED driver channels with independent digital control capabilities
• Includes two low quiescent current LDOs for auxiliary power supply requirements
• Supports PWM dimming for precise brightness adjustment and efficiency optimization

LED Driver IC Applications

• Backlighting for mobile devices and portable electronics
• White LED illumination systems requiring digital interface control
• Compact lighting modules with strict space constraints

LED Driver IC Procurement Notes

Verify the specific suffix PPYMT against the official Microchip datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with system voltage limits of 3V to 5.5V. Confirm thermal management requirements for the 14-TMLF package under maximum load conditions. Cross-reference RoHS compliance status with current manufacturer declarations.

LED Driver IC Selection Notes

Select this component when a multi-channel linear LED driver with integrated LDOs is required. It is suitable for applications needing digital control interfaces and PWM dimming. Consider the 14-TMLF footprint for board space limitations. Verify that the 20mA per channel output meets the target LED forward current requirements without external amplification.

LED Driver IC Part Context

This part belongs to the MIC2846 family of LED drivers from Microchip Technology. It succeeds older variants like the MIC2845 series, offering enhanced integration with dual LDOs. The device is designed for modern portable electronics where efficiency and small form factors are critical. It replaces discrete solutions by combining driver and regulator functions in a single IC.

LED Driver IC Replacement Considerations

Parametric equivalents include MIC2846A-MFYMT-TR, MIC2846A-MGYMT-TR, MIC2846A-PGYMT-TR, and MIC2846A-SCYMT-TR. These share the same core functionality but may differ in packaging or reel specifications. The obsolete MIC2845A-PPYMT-TR is a predecessor but lacks the integrated LDOs.
