Overview
The STP16CPC26XTR is a monolithic, low voltage, 16-bit constant current LED sink driver produced by STMicroelectronics. This device features a 16-bit shift register and data latches that convert serial input data into parallel output format. It is designed to drive LEDs with a constant current ranging from 5 mA to 90 mA, adjustable through an external resistor. The device supports high data rate transmission with a maximum clock frequency of 30 MHz and ensures overtemperature protection via thermal shutdown at 170 °C with a 15 °C hysteresis. The STP16CPC26XTR is available in four different packages: QSOP24, SO-24, TSSOP-24, and HTSSOP-24 (with exposed pad).
