MAX16128/MAX16129
Load-Dump/Reverse-Voltage Protection Circuits
ELECTRICAL CHARACTERISTICS (continued)
(V_IN = 12V, C_GATE-SOURCE = 1nF, T_A = -40NC to +125NC, unless otherwise noted. Typical values are at T_A = +25NC.) (Note 2)

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.
