The UCC3912 family of hot swap power managers provides complete power management, hot swap capability, and circuit breaker functions. The only component required to operate the device, other than supply bypassing, is
the fault timing capacitor, CT.
The TPS3808Gxx-Q1 microprocessor supervisory circuits monitor system voltages from 0.4 V to 5 V, asserting an open-drain RESETsignal when the SENSE voltage drops below a preset threshold or when the manual reset (MR)
pin drops to a logic low.
