UNDERVOLTAGE LOCKOUT
The undervoltage lockout (UVLO) threshold is 4.2 V with 0.5 V
hysteresis to prevent the device from power-on glitches. When
the PVIN1 or PVIN2 voltage rises above 4.2 V, Channel 1 or
Channel 2 is enabled and the soft start period initiates. When either
PVIN1 or PVIN2 drops below 3.7 V, it turns off Channel 1 or
Channel 2, respectively.
Data Sheet
THERMAL SHUTDOWN
In the event that the ADP2323 junction temperature exceeds
150°C, the thermal shutdown circuit turns off the regulator. A
15°C hysteresis is included so that the ADP2323 does not
recover from thermal shutdown until the on-chip temperature
drops below 135°C. Upon recovery, soft start is initiated prior to
normal operation.
