The UCC3918 is a low on-resistance hot swap power manager that integrates a 0.075-Ω MOSFET to provide power management, hot swap capability, and circuitbreaker functions for unidirectional current flow in 3 V to 6 V applications. It is offered in a 16-pin DP package with an exposed thermal pad for heat dissipation. The device supports programmable fault current from 0 A to 4 A and maximum sourcing current up to 5.1 A, with fast overload protection and a fixed 3% duty cycle during sustained faults. An open-drain fault output indicates shutdown conditions, and sleep mode draws 5 μA maximum. Thermal shutdown and undervoltage lockout are integrated.
