7.3.3.2.2.2 Fault Transmitting when BQ79600-Q1 in SLEEP

Because data communication is not available in SLEEP mode, the device provides following options to transmitting fault information:

  • Transmit the Heartbeat tone (enabled by [HB_TX_EN], used to check integrity of cable between bridge and first stack device). Device does not transmitted fault tone as it has NFAULT.
  • Detect Heartbeat and Fault tone, enabled, by [TONE_RX_EN].

These tones are transmitted in the same direction as a communication command frame, which is based on the CONTROL1[DIR_SEL] setting. For the tone signal to return back to BQ79600-Q1 (so NFAULT can be triggered if needed), a Ring architecture must be used to support transmitting fault status in SLEEP mode.

GUID-339A1B2C-432E-4918-AF1B-996964190BCA-low.gif Figure 7-26 Heartbeat and Fault Tone Examples

Both the Heartbeat and Fault Tone are a type of tone similar to the communication. One main difference is a communication tone only transmits with a single burst of couplets, while Heartbeat and Fault Tones are sent with a burst of couplets periodically. See Figure 7-21 for details.
