1378

Overview

The Adafruit Industries LLC part number 1378 is a WS2811 LED driver chip module, supplied in a 10-pack configuration. This component functions as a linear LED driver IC featuring three outputs. It supports an output current of 18.5mA per channel and operates within a junction temperature range of -25°C to 85°C. The device is packaged as a module designed for integration into low-power LED applications.

Feature Summary

• Integrates WS2811 LED driver technology for signal control
• Provides three distinct output channels for LED arrays
• Utilizes linear topology for dimming capabilities

Applications

• Indicator light circuits
• Low-power display systems
• LED array prototyping

Procurement Notes

Verify the specific package type and pinout compatibility with your target PCB layout before ordering. Confirm that the 18.5mA per channel current rating meets the requirements of your connected LEDs. Ensure the operating temperature range aligns with your environmental conditions. Check for any required external components not included in the module pack.

Selection Notes

Select this component when a dedicated linear driver for WS2811-compatible LEDs is required. Consider the three-output architecture if driving multiple independent LED strings from a single source. Evaluate the thermal performance at the upper limit of the specified junction temperature range for long-term reliability in enclosed designs.
