STMicroelectronics LED Drivers STP16CPPS05XTTR

The STP16CPPS05XTTR is a low voltage, 16-bit constant current LED sink driver designed for LED panel displays. It features a 16-bit serial-in, parallel-out shift register that feeds a 16-bit D-type storage register, allowing for efficient control of LED brightness. The output current can be adjusted from 3 to 40 mA through an external resistor, enabling precise light intensity control from 0% to 100%. This device supports a supply voltage as low as 3 V and is compatible with 3.3 V microcontrollers, making it suitable for various applications. It includes an auto power-saving feature that enhances energy efficiency without requiring external intervention. The STP16CPPS05XTTR can drive outputs up to 20 V, facilitating the connection of multiple LEDs in series. With a high clock frequency of 30 MHz, it is capable of handling high data rate transmissions. The TSSOP package with an exposed pad improves thermal dissipation, enhancing the device's performance in demanding applications.
