# 16\-bit Constant Current LED Driver (Component)

## Description

16\-Channel Constant\-Current LED Driver IC – The STMicroelectronics STP16CPC26PTR drives LEDs using a serial 16\-bit shift register and data latches with parallel constant\-current outputs\. It supports 3–5\.5 V supply voltage, 5–90 mA adjustable output current per channel, 20 V output capability, and a 30 MHz maximum clock frequency\. LED brightness is controlled through the output\-enable \(OE\) pin\. It includes thermal shutdown protection and is housed in a 24\-pin QSOP surface\-mount package\.
