18 V, 60 A, 0.6 m RDS(on) Hot-Swap eFuse Switch
DESCRIPTION
FEATURES
The SiC32301, SiC32302, SiC32303, and SiC32304 are
programmable hot swap e-fuses for high current
applications such as servers, data storage, and
communication products. They contain a high side MOSFET
and control circuitry that enables them to work as
stand-alone devices, or to be controlled by a hot-swap
controller. The SiC32301, SiC32302, SiC32303, and
SiC32304 drive up to 60 A of continuous current per device.
• 4.5 V to 18 V operating input range
• 25 V guaranteed maximum input tolerance
• Maximum 60 A output current
• Integrated switch with lower RDS(on) 0.6 m
• Built-in MOSFET driver
• Integrated current sensing with sense output
• Separate current sensing output used to program
over-current value
The SiC32301, SiC32302, SiC32303, and SiC32304 limit the
inrush current to the load when a circuit card is inserted into
a live backplane power source, thereby limiting the
backplane's voltage drop.
• Built-in soft start and insertion delay
• Output short-circuit protection
• Over-temperature protection
The devices offer many features to simplify system designs.
They provide an integrated solution for monitoring output
current and die temperature, eliminating the need for an
external current sensing shunt resistor, power MOSFET,
and thermal sensing device.
• Built-in fuse health diagnostics
• Fault and power good signal outputs
• Parallel operation for higher current applications,
SiC32301 and SiC32303 only
The SiC32301, SiC32302, SiC32303, and SiC32304 detect
the power FET gate, source, and drain short conditions, in
addition to feedback to the controller. Also, the SiC32301
and SiC32303 can be operated in parallel for higher current
applications. The SiC32301, SiC32302, SiC32303, and
SiC32304 are available in a 5 mm x 5 mm QFN package.
• Analog temperature report
• Output voltage power down control
• Available in a FCQFN 5 mm x 5 mm package
APPLICATIONS
• Hot swap
• PC cards
• Disk drives
• Servers
• Networking
