APPLICATIO S I FOR ATIO

Shutdown Modes

The LTC4557 can enter a low current shutdown mode by

one of two methods. First, the ENABLE pin can be brought

LOW by the controller to directly shut down the part. The

power-on-reset circuit automatically puts the part into

shutdown mode.

Ultralow Shutdown Current

In either of the two shutdown modes, the shutdown

current is less than 1

µA. For applications that require

a single microampere.
