(1) The bq2060A times out when any clock low exceeds TTIMEOUT.
(2) THIGH Max. is minimum bus idle time. SMBC = 1 for t > 50 ms causes reset of any transaction involving bq2060A that is in progress.
(3) TLOW:SEXT is the cumulative time a slave device is allowed to extend the clock cycles in one message from initial start to the stop.
The bq2060A typically extends the clock only 20 ms as a slave in the read byte or write byte protocol.
(4) TLOW:MEXT is the cumulative time a master device is allowed to extend the clock cycles in one message from initial start to the stop.
The bq2060A typically extends the clock only 20 ms as a master in the read byte or write byte protocol.
