Electrical Characteristics

In general, minimum and maximum values are testing requirements. However, some parameters may not be

tested in production because they are guaranteed by design and device characterization. Typical values reflect the

design center or nominal value of the parameter; they are for information only and are not a requirement. Minimum

and maximum values apply across the entire temperature range (–40 °C to +85 °C) and entire battery range
