4 / 60 page  bq2063 SBS v1.1COMPLIANT LiION GASGAUGE IC WITH PROTECTOR INTERFACE SLUS468E− MAY 2001 − REVISED APRIL 2002 4 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 SMBus ac specifications, TA = −20°C to 70°C, 2.7 V < VCC < 3.7 V (unless other noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT FSMB SMBus operating frequency Slave mode, SMBC 50% duty cycle 10 100 kHz FMAS SMBus master clock frequency Master mode, no clock low slave extend 51.2 kHz TBUF Bus free time between start and stop 4.7 µs THD:STA Hold time after (repeated) start 4.0 µs TSU:STA Repeated start setup time 4.7 µs TSU:STO Stop setup time 4.0 µs THD:DAT Data hold time Receive mode 0 s THD:DAT Data hold time Transmit mode 300 µs TSU:DAT Data setup time 250 µs TTIMEOUT Error signal/detect See Note 3 25 35 ms TLOW Clock low period 4.7 µs THIGH Clock high period See Note 4 4.0 50 µs TLOW:SEXT Cumulative clock low slave extend time See Note 5 25 ms TLOW:MEXT Cumulative clock low master extend time See Note 6 10 ms NOTES: 3. The bq2063 times out when any clock low exceeds TTIMEOUT 4. THIGH Max. is minimum bus idle time. SMBC = SMBD = 1 for t > 50 µs causes reset of any transaction involving bq2063 that is in progress. 5. 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. 6. 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. HDQ16 ac specifications, TA = −20°C to 70°C, 2.7 V < VCC < 3.7 V (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT tCYCH Cycle time, host to bq2063 (write) 190 µs tCYCB Cycle time, bq2063 to host (read) 190 205 250 µs tSTRH Start hold time, host to bq2063 (write) 5 µs tSTRB Start hold time, bq2063 to host (read) 32 µs tDSU Data setup time 50 µs tDSUB Data setup time 50 µs t(DH) Data hold time 100 µs tDV Data valid time 80 µs tSSU Stop setup time 145 µs tSSUB Stop setup time 145 µs tRSPS Response time, bq2063 to host 190 320 µs tB Break time 190 µs tBR Break recovery time 40 µs Not Recommended For New Designs |
