temperature range, unless otherwise noted specifications are at T
A

C, V
IN
= 12V, CTL and GND = 0V. Current into a pin is positive
and current out of a pin is negative. All voltages are referenced to GND, unless otherwise specified.
Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2:
The LTC4414E is guaranteed to meet performance specifications
from 0
°
C to 85
°
C. Specifications over the –40
°
C to 85
°
C operating
temperature range are assured by design, characterization and correlation
with statistical process controls. The LTC4414I is guaranteed and tested
over the –40
°
to 125
°
operating temperature range.
Note 3:
This results in the same supply current as would be observed with
an external P-channel MOSFET connected to the LTC4414 and operating in
forward regulation.
Note 4:
V
IN
is held at 12V and GATE is forced to 9V. SENSE is set at 12V
to measure the source current at GATE. SENSE is set at 11.9V to measure
sink current at GATE.
Note 5:
V
IN
is held at 12V and SENSE is stepped from 12.2V to 11.8V to
trigger the event. GATE voltage is initially V
G(OFF)
.
Note 6:
V
IN
is held at 12V and SENSE is stepped from 11.8V to 12.2V to
trigger the event. GATE voltage is initially internally clamped at V
G(ON)
.
Note 7:
STAT is forced to V
IN
– 1.5V. SENSE is set at V
IN
– 0.1V to
measure the off current at STAT. SENSE is set V
IN
+ 0.1V to measure the
sink current at STAT.
Note 8:
STAT is forced to 9V and V
IN
is held at 12V. SENSE is stepped
from 11.8V to 12.2V to measure the STAT turn-on time defined when I
STAT
reaches one half the measured I
S(SNK).
SENSE is stepped from 12.2V to
11.8V to measure the STAT turn-off time defined when I
STAT
reaches one
half the measured I
S(SNK) .
