Usage Notes
1. Be sure to use SV
DD
in the highest potential within the IC.
2. Standby operation, reset operation
Pin 28 is a standby switch input pin.
You can get an active mode with high-level and standby mode with low-level. In a reset operation, all the functions
of the IC stop. In a reset mode (SV
DD
reset, V
REF
reset and thermal protection on), only a charge pump operates.
3. Power on and off be done in a standby mode (V
SB
: Low).
4. Do not use pin 13 (V
REF
) in an open state.
5. Take time to check the characteristics on use.
When changing an external circuit constant for use, consider not only static characteristics, but also transient charac-
teristics and external parts with respect to the characteristics difference among ICs so that you can get enough margin.
6. Keep each output pin from being short-circuited to SV
DD
or VM or GND (line-to-supply and line-to-ground fault)
and also between themselves (load short-circuit). Otherwise the IC will be damaged and is likely to get fired.
7. Be cautious on a dip soldering. Prior study is required.
