Figure 25. Delay for Sequencing
SD PIN IMPEDANCE
When connecting a resistor divider to the SD pin of the LM2744 some care has to be taken. Once the SD voltage
goes above VSD-IH, a 17 µA pull-up current is activated as shown in Figure 26. This current is used to create the
internal hysteresis (
≊170mV); however, high external impedances will affect the SD pin logic thresholds as well.
The external impedance used for the sequencing divider network should preferably be a small fraction of the
impedance of the SD pin for good performance (around 1k
Ω).
