The TLC5948ADBQ from Texas Instruments is a 16-channel, 16-bit, ES-PWM LED driver designed for applications requiring precise LED control. It offers a sink current capability of up to 60mA per channel and features 7-bit dot correction and 7-bit global brightness control for detailed dimming effects.
The device supports 16-bit grayscale control, providing 65,536 steps for enhanced spectrum or conventional PWM dimming. It operates with a VCC range of 3.0V to 5.5V and can drive LEDs with a power-supply voltage of up to 10V. The constant-current accuracy is high, with channel-to-channel typically ±0.6% and device-to-device typically ±1%.
Integrated features include error flags, fault detection, LED open and short detection, power good indication, and thermal shutdown to ensure reliable operation. The TLC5948ADBQ is available in a 24-SSOP surface mount package, suitable for various electronic designs. Its operating temperature range is -40°C to +85°C.
This LED driver is ideal for applications such as signage and displays where accurate and flexible LED illumination is critical. The inclusion of power-save mode and diagnostic features further enhances its utility in power-sensitive and robust system designs.
