FEATURES Integrated Circuit Breaker Function Integrated 0.2 Power FET SCSI, SCSI-2, SCSI-3 Compliant 1μA ICC When Disabled Programmable On Time Accurate 1.65A Trip Current and
2.0A Max Current Fixed 3% Duty Cycle Uni-Directional Switch Thermal Shutdown
DESCRIPTIONThe UCC3916 SCSI termpower manager provides complete power man-
agement, hot swap capability, and circuit breaker functions with minimal ex-
ternal components. For most applications, the only external component
requiredto operate the device, other than supply bypassing,isa timing ca-
pacitor which sets the fault time.
The current trip levelis internally setat 1.65A, and the maximum current
levelis also internally programmedfor 2A. While the output currentis below
the trip levelof 1.65A, the internal power MOSFETis switchedonata nom-
inal 220mΩ. When the output current exceeds the trip level but remains
less than the maximum current level, the MOSFET remains switched on,
but the fault timer starts charging CT. Once the fault timeis reached, the cir-
cuit will shutoff fora time which equatestoa 3% duty cycle. Finally, when
the output current reaches the maximum current level, the MOSFET transi-
tions from a switch to a constant current source.
The UCC3916is designedfor uni-directional current flow, emulatinga diode
in series with the power MOSFET.
The UCC3916 canbe putina sleep mode, drawing only 1μAof supply cur-
rent.
Other features include thermal shutdown and low thermal resistance Small
