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 1 F. 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 (3 A) 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
forward biased (V
If the part is reverse biased (V
pin will pull down 10 A 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 1m ESR capacitor
of at least 4.7 F. The LTC4411 is stable with ESRs down
to 0.2m . However stability improves with higher ESRs.
