TLC5948ADBQR

The TLC5948ADBQR from Texas Instruments is a 16-channel, 16-bit, ES-PWM LED driver designed for applications requiring precise illumination control. This linear LED driver offers a sink current capability of up to 60mA per channel and features 7-bit dot correction and 7-bit global brightness control for fine-tuning LED output.

Key electrical specifications include a VCC operating range of 3.0V to 5.5V and an LED power-supply voltage of up to 10V. The device boasts high accuracy with channel-to-channel variation typically ±0.6% and device-to-device variation typically ±1%. It supports a data transfer rate of 33 MHz, enabling efficient control of multiple LED channels.

Designed for surface mounting, the TLC5948ADBQR comes in a compact 24-SSOP package. Its operating temperature range is -40°C to 85°C, making it suitable for various environmental conditions. The driver includes features such as error flags, fault detection, and power-save mode, contributing to robust system performance. It is particularly well-suited for signage applications.

Additional features include auto display repeat, auto data refresh, and output leakage detection. The device also incorporates thermal shutdown protection and pre-thermal warning to ensure operational safety.
