TLC5916IDRG4

Overview

The TLC5916IDRG4 is an 8-bit constant-current LED sink driver manufactured by Texas Instruments. It features a boost topology and delivers up to 120 mA per output channel. The device operates within a supply voltage range of 3 V to 5.5 V and supports a switching frequency of 30 MHz. It is housed in a 16-pin SOIC-Narrow package with an operating temperature range from -40°C to +125°C.

Feature Summary

• Provides eight independent constant-current output channels for LED sinking applications.
• Integrates internal fault detection mechanisms including open LED, short-to-ground, and short-to-VLED diagnostics.
• Utilizes a serial interface for data input and control signal transmission.

Applications

• General LED lighting systems
• Signage illumination drivers
• Segment display driving circuits

Procurement Notes

Verify the specific suffix IDRG4 corresponds to the tape-and-reel packaging variant rather than tube packaging. Confirm RoHS compliance status and moisture sensitivity level requirements for surface-mount assembly processes prior to procurement.

Selection Notes

Select this component when designing circuits requiring precise constant-current regulation for multiple LEDs. Ensure the application voltage does not exceed the 5.5 V maximum limit and that the thermal environment remains within the specified -40°C to +125°C operational range.

Part Context

This part belongs to the TLC5916 series of 8-bit constant-current LED sink drivers. It serves as a linear driver solution suitable for applications demanding high brightness uniformity across multiple LED channels without external current-setting resistors.
