TLC59711PWP

Overview

The TLC59711PWP is a 12-channel, 16-bit Enhanced Spectrum Pulse Width Modulation (ES-PWM) RGB LED driver manufactured by Texas Instruments. It operates within a supply voltage range of 3.1 V to 3.5 V and features an integrated 3.3 V linear regulator. The device provides constant-current sinking with output currents of -2 mA (high) and 2 mA (low). It utilizes a 20-pin HTSSOP package and supports surface-mount installation. The operating temperature range spans from -40°C to +85°C, with a maximum power dissipation of approximately 3.12 W.

Feature Summary

• Integrates 16-bit ES-PWM grayscale control for high-fidelity color reproduction in RGB applications.
• Includes built-in fault detection mechanisms such as LED open detection and power good/error flags.
• Features an internal grayscale clock and watchdog timer to ensure stable operation without external timing components.

Applications

• RGB LED display systems requiring precise color mixing
• Architectural lighting control units
• Digital signage backlight drivers

Procurement Notes

Verify the specific suffix 'PWP' corresponds to the HTSSOP-20 tube packaging when ordering. Confirm that the 3.1 V to 3.5 V supply requirement aligns with your system design, as the device includes an internal 3.3 V regulator. Ensure thermal management capabilities are sufficient for the specified power dissipation limits under full load conditions.

Selection Notes

Select this component for designs requiring 12 independent channels with 16-bit resolution. It is suitable for applications needing integrated regulation and fault monitoring. Compare against the TLC5971 series variants if different package types or channel configurations are required. Ensure compatibility with the host controller's serial interface protocols.

Part Context

This part belongs to the TLC5971 family of LED drivers from Texas Instruments. It is functionally similar to the TLC59711 but distinguished by its specific pinout and packaging in the HTSSOP-20 format. It serves as a dedicated sink driver for RGB LEDs, offering enhanced spectrum PWM technology for improved visual performance compared to standard PWM drivers.

Replacement Considerations

The TLC5971PWPR is a reel-based variant of the same functional device. Verify package compatibility before substitution. No other direct cross-model replacements are confirmed in public documentation.
