DESCRIPTION
The SMH4803 is designed to control hot swapping of
plug-in cards operating from a single supply ranging from
20V to 500V. The SMH4803 hot-swap controller provides
under-voltage and over-voltage monitoring of the host
power supply, it drives an external power MOSFET switch
that connects the supply to the load, and also protects
against over-current conditions that might disrupt the host
supply. When the input and output voltages to the
SMH4803 controller are within specification, the
SMH4803 provides three
“
Power Good
”
logic outputs that
may be used to turn ON the loads, e.g. isolated-output DC-
DC converters, or drive LED status lights. The SMH4803
provides three separate
“
Power Good
”
logic outputs that
activate loads in a timed sequence. Additional features of
the SMH4803 include: temperature sense or master en-
able input, 2.5V and 5V reference outputs for expanding
monitor functions, two
“
Pin-Detect
”
enable inputs for fault
protection, and duty-cycle or latched over-current protec-
tion modes.
