The STP16CPC26XTR is a 16-bit constant current LED sink driver that is monolithic and low voltage. This article mainly introduces Circuit, Pinout, Datasheet and other detailed information about STMicroelectronics STP16CPC26XTR.

STP16CPC26XTR Description

The STP16CPC26XTR is a 16-bit constant current LED sink driver that is monolithic and low voltage. A 16-bit shift register and data latches are included in the device, which transforms serial input data to parallel output format. In the output stage, sixteen controlled current generators deliver a constant current of 5 mA to 90 mA to drive LEDs. A resistor is used to control the current from the outside.

The OE pin can be used to adjust the LED brightness from 0% to 100%.

The 20 V driving capabilities of the STP16CPC26XTR allow users to connect additional LEDs in series to each current source.

The device's high 30 MHz clock frequency allows for high data rate transmission.

Overtemperature events are protected by the thermal shutdown (170 °C with roughly 15 °C hysteresis).

QSOP24, SO-24, TSSOP-24, and HTSSOP-24 are the four packages available for the STP16CPC26XTR (with exposed pad).
