LTC4414

4414fc

The

● denotes specifications which apply over the full operating

temperature range, unless otherwise noted specifications are at TA = 25°C, VIN = 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: VIN 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 VG(OFF).

Note 6: VIN 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 VG(ON).

Note 7: STAT is forced to VIN – 1.5V. SENSE is set at VIN – 0.1V to

measure the off current at STAT. SENSE is set VIN + 0.1V to measure the

sink current at STAT.

Note 8: STAT is forced to 9V and VIN is held at 12V. SENSE is stepped

from 11.8V to 12.2V to measure the STAT turn-on time defined when ISTAT

reaches one half the measured IS(SNK). SENSE is stepped from 12.2V to

11.8V to measure the STAT turn-off time defined when ISTAT reaches one

half the measured IS(SNK) .
