ADP1710/ADP1711

Rev. 0 | Page 9 of 16

As can be seen, the EN pin has hysteresis built in. This prevents

on/off oscillations that can occur due to noise on the EN pin as

it passes through the threshold points.

The EN pin active/inactive thresholds are derived from the IN

voltage. Therefore, these thresholds vary with changing input

voltage. Figure 20 shows typical EN active/inactive thresholds

when the input voltage varies from 2.5 V to 5.5 V.

UNDERVOLTAGE LOCKOUT (UVLO)

The ADP1710/ADP1711 have an undervoltage lockout circuit,

which monitors the voltage on the IN pin. When the voltage on

IN drops below 1.95 V (minimum), the circuit activates, disabling

the OUT pin.
