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.
