Power Supply Circuits

Keep the impedance of the VSSand VSS1 lines as low as possible. Connect a large electrolytic capacitor across the VDD1
and VSS1 pins and close to the IC. Wherever possible, keep the grounds for the power supply circuits and the signal
circuits separate and connect the two at a single point.

Notes on Power-Supply Voltage Application

This IC has two power supply systems: VDD(VDD1) and VCC, and requires that applications observe the notes provided
here when applying or removing these voltages. In particular, if the VDD(VDD1) system power-supply voltage becomes
higher than the VCCsystem voltage while the VCCsystem voltage is not yet established (i.e. is less than VCCmin),
excessive currents may flow and the IC may be destroyed. To prevent destruction of the IC due to this phenomenon,
applications must, basically, follow the sequence described in item 1 below when turning the power supplies on or off.

1. When turning the power on, first apply the VCCvoltage (bring this voltage to a value above VCCmin), and then apply
the VDDvoltage. When turning the power off, first drop the VDDvoltage, and, after VDDis below VCCmin, then drop
the V

CC

voltage.

➁ Not impose any responsibility for any fault or negligence which may be cited in any such claim or litigation on

■ Information (including circuit diagrams and circuit parameters) herein is for example only; it is not guaranteed for
volume production. SANYO believes information herein is accurate and reliable, but no guarantees are made or implied
regarding its use or any infringements of intellectual property rights or other rights of third parties.

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 VCCare turned on and off at essentially the same time, the difference between VDDand VCC(e.g.

the distance in the figure marked as ∆0.5 V) must be held to be under 0.5 V while VCCis less than or equal to 3.0 V.

Another point is that a certain amount of time is required to stabilize the VCCsystem when VCCis first applied and the
IC is easily destroyed during this period. Inversely, when the power is removed, the VCCsystem 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 VCChas 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.
