I Usage Notes
1. Be sure to use SVDD 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 (SVDD reset, VREF reset and thermal protection on), only a charge pump operates.
3. Power on and off be done in a standby mode (VSB: Low).
4. Do not use pin 13 (VREF) 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 SVDD 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.
