APPLICATIO S I FOR ATIO

Power Down While Connected to a Battery

Another unique benefit of the LT6100 is that you can leave

it connected to a battery even when it is denied power.

When the LT6100 loses power or is intentionally powered

down, its inputs remain high impedance (see Figure 8).

This is due to the implementation of Linear Technology’s

Over-The-Top

powered down, the LT6100 inputs draw less than 1

µA of

current.
