STAP16DPS05中文资料低压16位恒定电流LED灌驱动器，具有输出错误检测和自动节能功能，用于汽车应用数据手册ST规格书

描述 Description

The STAP16DPS05 is a monolithic, low voltage, low current power 16-bit shift register designed for LED panel displays. The device contains 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 5-100 mA constant current to drive the LEDs.

The STAP16DPS05 features the open and short LED detections on the outputs.The STAP16DPS05 ensures the backward compatibility with the STP16C/L596. The detection circuit checks 3 different conditions, which can occur on the output line: short to GND, short to VO or open line. The data detection results are loaded in the shift register and shifted out via the serial line output. The detection functionality is implemented without increasing the pin number. Through a secondary function of the output enable and latch pin (DM1 and DM2 respectively), a dedicated logic sequence allows the device to enter or leave detection mode. Through an external resistor, users can adjust the output current of the STAP16DPS05, thus controlling the light intensity of the LEDs. In addition, the user can adjust the intensity of the brightness of the LEDs from 0% to 100% through the OE/DM2 pin. The STAP16DPS05 guarantees a 20 V output driving capability, allowing users to connect more LEDs in series. The high clock frequency, 30 MHz, also satisfies the system requirement of high volume data transmission. The 3.3 V of voltage supply is very useful for applications that interface any microcontroller from 3.3 V micro. Compared with a standard TSSOP package, the TSSOP exposed pad increases the capability of heat dissipation by a factor of 2.5.

简介

STAP16DPS05属于集成电路（IC）的LED驱动器。由ST制造生产的STAP16DPS05LED 驱动器器件属于 LED 驱动器电源管理集成电路 (PMIC) 系列，可通过标称固定电压的电源为负载（通常为发光二极管）提供电流，并且电流可控。它与用于电压调节的类似产品的主要区别在于，这类器件提供较低的反馈电压（以提高系统能效），而且通常可对器件工作点进行外部控制，可在照明应用中用于实现调光功能。
