UCC3916 SCSI Termpower Manager 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 DESCRIPTION The UCC3916 SCSI termpower manager provides complete power management, hot swap capability, and circuit breaker functions with minimal external components. For most applications, the only external component required to operate the device, other than supply bypassing, is a timing capacitor which sets the fault time. The current trip level is internally set at 1.65A, and the maximum current level is also internally programmed for 2A.
