3 Wake Sequence

The wake ping is applied by the microcontroller to the RX line of the BQ79616-Q1 device. This ping is an active low, and it has a low time of 2.5 ms. To wake the device:

  1. Send a wake ping (as described above)
  2. Wait (approximately10ms shutdown to active transition + approximately 600us propagation of wake) x number_of_devices, before any further communications.
