Product overview

Description

The STP16CPPS05 is a monolithic, low voltage, low current power 16-bit shift register designed for LED panel displays. The device features a 16-bit serial-in, parallel-out shift register that feeds a 16-bit D-type storage register. In the output stage, sixteen regulated current sources are designed to provide 3 to 40 mA of constant current to drive the LEDs.

The STP16CPPS05 output current can be adjusted through an external resistor to control the light intensity of the LEDs. LED brightness is adjustable from 0% to 100% via the OE pin.

The auto power-shutdown and auto power-ON feature allows the device to save power with no external intervention.

The STP16CPPS05 guarantees a 20 V output driving capability, allowing users to connect more LEDs in series. The high 30 MHz clock frequency makes the device suitable for high data rate transmission. The 3.3 V supply is well suited for applications which interface a 3.3 V MCU. Compared to a standard TSSOP package, the TSSOP with exposed pad increases heat dissipation capability by a factor of 2.5.
