MAX16128/MAX16129
Load-Dump/Reverse-Voltage Protection Circuits
Typical Operating Characteristics
(V
IN
= 12V, T
A
= +25NC, unless otherwise noted.)
Note 2: All parameters are production tested at T
A
= +25NC. Limits over the operating temperature range are guaranteed by
design and characterization.
Note 3: The MAX16128/MAX16129 power up with the external MOSFETs in off mode (V
GATE
= V
SRC
). The external MOSFETs turn
on t
START
after the devices are powered up and all input conditions are valid.
ELECTRICAL CHARACTERISTICS (continued)

= 1nF, T
A
= -40NC to +125NC, unless otherwise noted. Typical values are at T
A
