Features
Description
These devices power distribution switches are
intended for application where heavy capacitive
loads and short circuits are likely to be
encountered. These devices incorporate 80mΩ N-
channel MOSFET high-side power switches for
power-distribution systems that require multiple
powers switches in a single package. Each switch
is controlled by an independent logic enable input.
Gate drive is provided by an internal charge pump
designed to control the power-switch rise times
and fall times to minimize current surges during
switching.

Current Limit (mA)
The
components and allows operation from supplies
as low as 2.7 V. When the output load exceeds
the current-limit threshold or a short is present,
these devices limit the output current to a safe
level by switching into a constant-current mode,
pulling the overcurrent (OCx) logic output low.
When continuous heavy overloads and short
circuits increase the power dissipation in the
switch, causing the junction temperature to rise, a
thermal protection circuit shuts off the switch to
prevent damage. Recovery from a thermal
shutdown is automatic once the device has
cooled sufficiently. Internal circuitry ensures the
switch remains off until valid input voltage is
present.
