Part Number: TLC5947
Hello,
I am using TLC5947DAPR in my current design.
I have connected BLABK, SCLK, SIN and XTAL signal to controller through Level Shifter and put the Pull up resistor (3.3V) on BLANK Signal in Controller Board.
At Output, I have placed Pull Up resistors (Pin#5 to 23) and connected to MOSFET through Inverter to keep the MOSFET OFF in default condition but some how when I power ON, the MOSFETs are ON for some time and then OFF.
I want to know the output pin condition of TLC5947DAPR at Power ON, here I have kept the BLANK pin High from controller board.
Kindly share the actual working condition of TLC5947DAPR at power ON i.e the status of each pins.
Please find the below Image for your reference.
