BQ76PL455A-Q1: BQ76pl455A-Q1 Wakeup issue

Part Number: BQ76PL455A-Q1

Hello,

I am facing an issue with the BQ76PL455A-Q1 Wakeup signal. I have 2 IC in daisy chain configuration. I have followed the Software Design Reference Application note from TI. I am getting the code work only when I Reset my system 3-4 times. The code usually get stuck during Reading of the IC device Address. It is unable to Read the Top stack address and hangs up the code.

I think there is some issue with the Wakeup of the IC's. I am following the below sequence for Waking up the IC's on Wakeup Pin.

0 - 1 - 0 (Delay of 1 milli second) --> 2 times.

Am I making any Error over here? If else, Can you help me solve this issue?

Thank you

Dear Sir,

My issue has been solved. I was facing some trouble in Waking up the Slave IC of BQ76PL455A-Q1. I was able to solve the problem by changing the timing of wakeup sequencing. Now, I am able to work my code in the single shot.

Thanks
