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
(–
36 V to
–70 V). Unless otherwise specified, typical is defined as 25 °C, V
