Electrical Characteristics
TA = –40 °C to +85 °C, unless otherwise specified.
Minimum and maximum values are testing requirements. Typical values are characteristics of the device and are
the result of engineering evaluations. Typical values are for information purposes only and are not part of the test-
ing requirements.

* VBAT is used only as a reference for internal protection circuitry. If VBAT rises above –10 V, the device will enter an all OFF state and remain in
this state until the battery voltage drops below –15 V.
