STP16DPS05PTR

Overview

The STP16DPS05PTR 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 feeding a 16-bit D-type storage register. The output stage provides sixteen regulated current sources delivering 5-100 mA constant current to drive LEDs. It features open and short LED detections on outputs, checking for shorts to GND or VO and open lines. The device supports a 3 V supply, 20 V output driving capability, and a 30 MHz clock frequency.

Feature Summary

• Monolithic 16-bit shift register with serial input and parallel output architecture
• Integrated open and short circuit detection for output line fault monitoring
• Adjustable constant current output via external resistor for light intensity control
• High thermal efficiency TSSOP exposed pad package design

Applications

• LED panel displays
• High data rate transmission systems
• Applications interfacing with 3.3 V microcontrollers
