LC4105V
However, there are many cases where it is not possible to control the power-supply voltage on/off sequence. This IC is
actually capable of supporting the on/off sequence described in item 2 below.
2. If VDD (VDD1) and VCC are turned on and off at essentially the same time, the difference between VDD and VCC (e.g.
the distance in the figure marked as ∆0.5 V) must be held to be under 0.5 V while VCC is less than or equal to 3.0 V.

Another point is that a certain amount of time is required to stabilize the VCC system when VCC is first applied and the
IC is easily destroyed during this period. Inversely, when the power is removed, the VCC system state is easily retained
and as a result the device cannot be destroyed easily. In actual use, one can consider there to be a certain amount of
margin for removing the VDD (VDD1) voltage even after VCC has already been dropped. However, this margin varies
with sample-to-sample variations in the IC itself and with the details of the application circuit, and careful analysis and
consideration of the actual usage conditions is required to assure that the IC will not be destroyed if the sequences in
items 1 or 2 are not observed.
3. Note that when power is turned off and then immediately turned back on again, many circuit designs may fail to meet
the conditions for the sequences described in items 1 and 2 above. Be sure to take this into account when designing
applications that use this IC.
