NOTES
1
This specification guarantees that both the high and low trip point of the comparator fall within the 210 mV to 230 mV range.
2
This specification guarantees that the output voltage of the fixed versions will always fall within the specified range. The waveform at the sense pin will exhibit a saw-
tooth shape due to the comparator hysteresis.
3
100 k
resistor connected between a 5 V source and the AO pin.
4
The ADP1110 is guaranteed to withstand continuous application of +1.6 V applied to the GND and SW2 pins while V
IN
, I
LIM
, and SW1 pins are grounded.
5
All limits at temperature extremes are guaranteed via correlation using standard statistical quality control methods.
Specifications subject to change without notice.
