Electrical Specications
Unless otherwise noted, for sinusoidal waveform input and reference resistor R
ref
= 24 kW, all typical values are
at T
A
= 25°C and V
CC
= 5 V; all Minimum/Maximum specications are at Recommended Operating Conditions.
Notes:
1. Threshold of falling V
CC
with hysteresis of 0.2 V (typ.).
2. Threshold of rising junction temperature with hysteresis of 20°C (typ.).
3. See Application Information section for more information on the load detection feature.
4. See Figure 3 for the plot of supply current versus Tx output current.
