Application note
Power saving and LED status detection
using the STP16DPPS05 device
Introduction
Today, the use of LEDs is growing in many market segments, including portable
applications, due to their improving performance and lower cost.
This new scenario requires that LED drivers be capable of providing good performance at
low current, and include power saving capabilities.To address these requirements,
STMicroelectronics has introduced the STP16xPPx05 family of LED drivers.
This application note describes the STP16DPPS05 low voltage 16-bit constant current LED
sink driver, with particular focus on two important features: output error detection and auto
power-saving.
