• Description: 36v, Low Loss Powerpath Controller For Large Pfets
• Manufacturer: Linear Technology Corporation

ELECTRICAL CHARACTERISTICS
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
to measure the source current at GATE. SENSE is set at 11.9V to measure
sink current at GATE.
