This document describes the features of the STP16DP05 low voltage 16-bit constant current LED sink driver, including adjustable output current, short and open output error detection.
The STP16DP05 is a monolithic, low voltage, low current power 16-bit shift register designed for LED panel displays. It contains a 16-bit serial-in, parallel-out shift register that feeds a 16-bit D-type storage register. The output stage features sixteen regulated current sources designed to provide 5-100 mA constant current to drive LEDs.
The device features open and short LED detections on the outputs, checking for short to GND, short to Vo, or open line conditions. Users can adjust the output current through an external resistor, and LED brightness can be adjusted from 0% to 100% via the OE/DM2 pin. The STP16DP05 guarantees a 20 V output driving capability and operates with a supply voltage down to 3 V.
