DESCRIPTION
The MPQ5069 is a hot-swap protection device
designed to protect circuitry on its output from
transients on its input. It also protects its input
from undesired shorts and transients coming
from its output.
During start-up, the slew rate at the output limits
the inrush current. An external capacitor at the
SS pin controls the slew rate.
The maximum output load is current-limited using
a sense FET topology whereby a low-power
resistor from the ISET pin to ground controls the
magnitude of the current limit. An internal charge
pump drives the gate of the power device,
allowing for a power FET with a very low on
resistance of 7mΩ. The MPQ5069 includes an
IMON option to produce a voltage proportional to
the current through the power device, as set by a
resistor from the IMON pin to ground.
The MPQ5069’s fault protections include currentlimit
protection, thermal shutdown, and damaged-
MOSFET detection. Both the current limit and
thermal shutdown offer configurable auto-retry
and latch-off mode. The device also features
under-voltage protection.
The MPQ5069 is available in a QFN-22
(3mmx5mm) package and is AEC-Q100 qualified.
