MIC5400YWM

LED Driver IC Overview

The MIC5400YWM is a 16-channel LED display driver manufactured by Microchip Technology, housed in a 28-SOIC surface-mount package. It supports 3.5 to 5-digit displays with up to 16 segments per digit. The device operates on a supply voltage range of 4.75V to 5.5V and draws a maximum power current of 2mA. Each output channel provides a linear dimming capability with a sink current of 30mA. The component functions within an operating temperature range of -40°C to +125°C (junction temperature) and complies with RoHS3 standards.

LED Driver IC Feature Summary

• Provides 16 independent output channels for driving LED segments with linear dimming control
• Supports 3.5, 4.5, and 5-digit display configurations with up to 16 segments per digit
• Integrates internal switching circuitry for efficient power management
• Operates reliably across extended industrial temperature ranges

LED Driver IC Applications

• Multi-digit numeric LED display systems
• Industrial instrumentation panels requiring segment control
• Consumer electronics with high-segment-count LED readouts

LED Driver IC Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and tape/reel specifications. Ensure compatibility with your PCB footprint for the 28-SOIC variant. Cross-reference the datasheet for moisture sensitivity level and handling precautions during assembly. Confirm that the 30mA per channel rating meets your LED load requirements without exceeding thermal limits.

LED Driver IC Selection Notes

Select this component when a high-density LED driver with linear dimming is required for multi-digit displays. The 28-SOIC package suits surface-mount assembly processes. Consider the 2mA supply current for low-power applications. Verify that the 5.5V maximum supply voltage aligns with your system's logic levels. The extended junction temperature range supports demanding environmental conditions.

LED Driver IC Part Context

The MIC5400 belongs to Microchip’s family of LED display drivers, designed for replacing older TTL-compatible drivers like the MM5450 series. It offers improved power efficiency and integration compared to legacy discrete solutions. The YWM suffix specifically denotes the 28-SOIC package variant. This part bridges the gap between simple shift registers and complex microcontroller-driven displays.

LED Driver IC Replacement Considerations

MIC5400YWM-TR is the tape-and-reel version of the same functional device. Check datasheets for pinout compatibility if substituting with other 16-channel drivers.
