18 V, 60 A, 0.6 m R_DS(on)Hot-Swap eFuse Switch

DESCRIPTION

FEATURES

The SiC32311 is a programmable hot swap e-fuse for high

current applications such as servers, data storage, and

communication products. It contains a high-side MOSFET

and other control circuitry that enables it to work as

stand-alone device, or to be controlled by a hot-swap

controller. The SiC32311 drives 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 R_DS(on)of 0.6 m

• Built-in MOSFET driver

• Integrated current sensing with sense output

The SiC32311 limits 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.

• Separate current sensing output used to program

over-current value

• Built-in soft start and insertion delay

• Output short-circuit protection

• Over-temperature protection

The device offers many features to simplify system designs.

It provides 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 status report

The SiC32311 detects the power FET gate, source, and

drain short conditions, in addition to feedback to the

controller. SiC32311 can be operated in parallel for higher

current applications. The SiC32311 is available in a

PowerPAK MLP32-55.

• Parallel operation for higher current applications

• Analog temperature report

• Available in a PowerPAK MLP32-55 package

APPLICATIONS

• Hot swap

• PC cards

• Disk drives

• Servers

• Networking
