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.
Table 4. Power Supply Specifications
* V
BAT
is used only as a reference for internal protection circuitry. If V
BAT
rises above –10 V, the device will enter an all OFF state and will remain
in the all OFF state until the battery voltage drops below –15 V.
Table 5. Break Switches, 1 and 2
* This parameter is not tested in production. Choice of secondary protector should ensure this rating is not exceeded.
Applied voltage is 100 Vp-p square wave at 100 Hz.
