The STP16DPS05 is a monolithic, low voltage, low current power 16-bit shift register designed for LED panel displays. It features open and short LED detections on the outputs.
The STP16DPS05 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, driving sixteen regulated current sources to provide 5-100 mA constant current to LEDs.
The device features open and short LED detection on the outputs, implemented without increasing the pin count. Users can adjust the output current via an external resistor and control brightness from 0% to 100% via the OE/DNZ pin. It supports a 30 MHz clock frequency and is available in high thermal efficiency TSSOP exposed pad packages.
