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.

Specifications of any and all SANYO Semiconductor products described or contained herein stipulate
the performance, characteristics, and functions of the described products in the independent state,
and are not guarantees of the performance, characteristics, and functions of the described products
as mounted in the customer's products or equipment. To verify symptoms and states that cannot be
evaluated in an independent device, the customer should always evaluate and test devices mounted
in the customer's products or equipment.
SANYO Semiconductor Co., Ltd. strives to supply high-quality high-reliability products. However, any
and all semiconductor products fail with some probability. It is possible that these probabilistic failures
could give rise to accidents or events that could endanger human lives, that could give rise to smoke or
fire, or that could cause damage to other property. When designing equipment, adopt safety measures
so that these kinds of accidents or events cannot occur. Such measures include but are not limited to
protective circuits and error prevention circuits for safe design, redundant design, and structural design.
