Appendix H
BATS Electrical Specifications
This section describe the electrical characteristics of the Supply Voltage Sense module.
H.1
Static Electrical Characteristics
Table H-1. Static Electrical Characteristics - Supply Voltage Sense - (BATS)
Characteristics noted under conditions -40°C

J
150°C unless otherwise noted. Typical values reflect the
approximate parameter mean at T
A
= 25°C under nominal conditions unless otherwise noted.
All parameters in this table assume a in series connected R
VSENSE_R
at VSENSE pin unless otherwise noted and
are valid on input voltage of R
VSENSE_R
and not on VSENSE pin.
