NOTES:
1. VPP - VPROGmust be within 11.5V to 12.0V.
2. Applies only if a 12.0V supply is connected. If VPP and VDD are tied together, current is less than
1A.
3. Input load is to GND.
4. Voltage difference between VDD and 1-W.
5. Voltage difference between VPP and 1-W.
6. 8.68s (115.2kbps), 52s (19.2kbps), 17.36s (57.6kbps), 104s (9.6kbps).
7. Nominal values; tolerance = ±5%.
8. At VCC = 5.0V and 100pF load to GND.
9. See Table 7, Function and Speed Matrix.
10. Independent of baud rate.
11. Minimum at 115.2kbps, maximum at 9.6kbps.
12. The master reset cycle is complete after tMR is over.
13. Minimum value at Overdrive speed; maximum value at standard speed.
14. is the time to complete the activity on the 1-Wire bus; values range from 0 (configuration
command) up to 5130s (alarming presence pulse).
15. With standard and flexible speed the total capacitive load of the 1-Wire bus should not exceed 20nF,
otherwise the active pullup on threshold VIAPO may not be reached in the available time. With
Overdrive speed the capacitive load on the 1-Wire bus must not exceed 1nF.
16. Baud rate calibration is valid at a static VDD operating point. Post calibration changes in VDD by more
than 5% may cause calibration error to exceed 5%. The DS2480B requires a 1-Wire reset command
sent by the host at a data rate of 9600bps for calibration. Data rates of 115200bps or higher during
calibration may put the DS2480B in an undefined state, requiring a power-down reset to restore
normal operation.
17. Not production tested.
