Note 3: All devices are 100% production tested at T
A
= +25癈. Limits over temperature are guaranteed by design.
Note 4: The input offset current is illustrated in Figure 2.
Note 5: Effective differential input resistance is defined as the differential resistance between V
DD
and GND, see Figure 2.
Note 6: A 20V glitch on input voltage, which takes V
DD
below V
ON
shorter than or equal to t
OFF_DLY
does not cause the device to
exit power-on mode.
Note 7 Referred to feedback regulation voltage.
Note 8: Referred to LDO feedback regulation voltage.
Note 9: The WAD Detection Rising and Falling Thresholds control the isolation power MOS transistor. To turn the DC-DC on in
WAD mode, the WAD must be detected and the V
DD
must be within the V
DD
voltage range.
