Overview
The TLC6948RGER is a 16-channel, 16-bit Enhanced Serial Pulse-Width Modulation (ES-PWM) constant-current LED driver manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 5.5 V and supports up to 48 multiplexing levels. The device features a 24-pin VQFN package with an exposed pad, designed for surface-mount applications. It functions across a temperature range of -40°C to +85°C and utilizes a serial interface for data input.
Feature Summary
- Supports 16-bit ES-PWM for high-resolution grayscale control
- Enables up to 48 multiplexing levels for complex display architectures
- Provides constant-current output regulation for consistent LED brightness
Applications
- LED lighting systems
- Display backlight drivers
- General-purpose LED matrix control
Procurement Notes
Verify the specific suffix RGE confirms the VQFN package and pin configuration. Ensure compatibility with the host controller's serial interface timing requirements. Confirm that the operating temperature range meets the environmental constraints of the final assembly. Validate power supply stability within the specified 3 V to 5.5 V window during operation.
Selection Notes
Select this component when high-resolution grayscale is required for LED arrays. The 16-bit resolution allows for smooth dimming transitions. The integrated multiplexing capability reduces external component count compared to non-multiplexed drivers. Consider the thermal performance of the VQFN package in dense PCB layouts.
Part Context
This part belongs to the TLC6948 family of LED drivers from Texas Instruments. It is designed for applications requiring precise current control and high channel counts. The RGE suffix denotes the specific 24-pin VQFN packaging variant suitable for space-constrained designs.
Replacement Considerations
Check for direct pin-compatible alternatives within the same TI series. Verify if other models offer different multiplexing limits or package options while maintaining similar electrical characteristics.
