Hi,
Datasheet says it is "non latching". --> Re-enabling should work.
AC_OK
Brownout protection input. A voltage below 0.45 V shuts down (not latched) the IC,
lowers its consumption and clears the latch set by latched protections (DIS > 4.5 V,
SS > 6.4 V, VFF > 6.4 V). IC’s operation is re-enabled as the voltage exceeds
0.45 V. The comparator is provided with current hysteresis: an internal 15 μA
current generator is ON as long as the voltage on the pin is below 0.45 V and is
OFF if this value is exceeded. Bypass the pin with a capacitor to GND (pin 3) to
reduce noise pick-up. Tie to Vcc with a 220 to 680 kΩ resistor if the function is not
used
Is there any possibility that an undervoltage or overvoltage occurs to pins: 6, 7, 8, 10, 14, 12, 13
This could cause a "latch up" condition to the complete chip or parts of the chip.
Consider protection circuits if you are not sure..
