*1. Since products are not screened at high and low temperature, the specification for this temperature range is guaranteed by
design, not tested in production.
*2. The temperature characteristics of VDIOV is determined depending on the setting of VDIOV, and accords closely with the
temperature characteristics of ON resistance of the charge-discharge control FET.
Refer to "2. 5 VDIOV vs. Ta" in " Characteristics (Typical Data)" for details.
