PI FU CTIO S

IN (Pin 1): Ideal Diode Anode and Positive Power Supply

for LTC4411. When operating LTC4411 as a switch it must

be bypassed with a low ESR ceramic capacitor of 1µF. X5R

and X7R dielectrics are preferred for their superior voltage

and temperature characteristics.

GND (Pin 2): Power and Signal Ground for the IC.

CTL (Pin 3): Controlled Shutdown Pin. Weak (3µA) Pull-

Down. Pull this pin high to shut down the IC. Tie to GND

to enable. Can be left floating when not in use.

STAT (Pin 4): Status Condition Indicator. This pin indi-

cates the conducting status of the LTC4411. If the part is

pin will pull down 10µA through an open-drain. When

terminated to a high voltage through a 470k resistor, a

high voltage indicates diode conducting. May be left

floating or grounded when not in use.

OUT (Pin 5): Ideal Diode Cathode and Output of the

LTC4411. Bypass OUT with a nominal 1mΩ ESR capacitor

of at least 4.7µF. The LTC4411 is stable with ESRs down

to 0.2mΩ. However stability improves with higher ESRs.
