* Absolute Maximum Ratings are those values beyond which damage to device
may occur. Functional operation under these conditions is not implied.
Continuous operation of the device at the absolute rating level my affect
reliability. All voltages are references to VNN pin.

( 1 ): HV110 will work in both Positive and Negative voltage applications, the maximum differential voltage between the VPP and VNN pins must not be exceeded.
( 2 ): UVLO Threshold to be modified using external resistors, when a zener diode is connected to VPP pin. (See Signature Detection)
( 3 ): Shorted-circuit timer starts after POR timer. If VOUT does not charge at least 90% Vin before tSC then a shorted-circuit condition exists.
( 4 ): Under-current timer starts when IOUT goes below IMIN. If IOUT stays below IMIN longer than tUC then MOSFET is turned off due to under current condition.
( 5 ): If the output current is in an overload or shorted load condition then the output immediately goes to current limit and starts the over-current timer. If IOUT does
not drop back below ILIMIT before the timer expires then an over current condition exists. The timer is immediately reset when a fault is cleared.
( 6 ): Time for fast return to limit circuit to react.
