MPQ5069GQV-AEC1-Z集成电路（IC）的配电开关负载驱动器规格书PDF中文资料

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.
