The UCC3921 family of negative floating hot swap power managers provides plete power management, hot swap, and fault handling capability.
The IC is referenced to the negative input voltage and is powered through an external resistor connected to ground, which is essentially a current drive as opposed to the traditional voltage drive.
The onboard 10V shunt regulator protects the IC from excess voltage and serves as a reference for programming the maximum allowable output sourcing current during a fault.
