3 Description
The LM66200 is a dual ideal diode device with a
voltage rating of 1.6 V to 5.5 V and a maximum
current rating of 2.5 A per channel. The device
uses N-channel MOSFETs to switch between supplies
while providing a controlled slew rate when voltage is
first applied.
Due to its low quiescent of 1.32 μA (typical) and low
standby current of 50 nA (typical), the LM66200 is
ideal for systems where a battery is connected to one
of the inputs. These low currents extend the life and
operation of the battery when in use.
The LM66200 uses automatic diode mode to prioritize
the highest voltage supply and pass it through to the
output. The active low enable pin (ON) disables both
channels, allowing the user to put the device into
shutdown mode when neither supply is needed.
