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.
Enhanced Power Switch
Data Brief
SO-8
The charge pump requires no external
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.
