DS2482-100: Single-Channel 1-Wire Master

Since a 885ꢁ pullup resistor, as would be required to meet the rise time specification at fast speed and 400pF bus

capacitance, is lower than Rpmin at 5.5V, a different approach is necessary. The "Max. Load…" line in Figure 12 is

generated by first calculating the minimum pullup resistor at any given operating voltage ("Minimum Rp" line) and

then calculating the respective bus capacitance that yields a rise time of 300ns.

Only for pullup voltages of 3V and lower can the maximum permissible bus capacitance of 400pF be maintained. A

reduced bus capacitance of 300pF is acceptable for pullup voltages of 4V and lower. For fast speed operation at

any pullup voltage, the bus capacitance must not exceed 200pF. The corresponding pullup resistor value at the

voltage is indicated by the "Minimum Rp" line.
