STMicroelectronics STP24DP05
The STP24DP05 has a dedicated pin to activate the outputs with a sequential delay, that prevents inrush current during output turn-ON. The device detection circuit checks 3 different conditions that can occur on the output line: short to GND, short to VO, or open line. The data detection results are loaded in the shift registers and shifted out via the serial line output.| Part No. | STP24DP05 |

DESCRIPTION
The 8 x 3 shift register data flow sequence order can be managed through two dedicated pins. The detection functionality is activated with a dedicated pin or alternatively, through a logic sequence that allows the user to enter or exit detection mode. Through three external resistors, the user can adjust the output current for each 8-channel group, therefore controlling the light intensity of LEDs. The STP24DP05 guarantees a 20 V output driving capability, allowing the user to connect more LEDs in series. The high clock frequency, 25 MHz, makes the device suitable for high data rate transmission. The 3.3 V of voltage supply is useful for applications that interface any microcontroller from 3.3 V.
