Latchable Negative Floating Hot Swap Power Manager UCC1921 UCC2921 UCC3921 FEATURES • Precision Fault Threshold • Programmable: Average Power Limiting, Linear Current Control, Overcurrent Limit and Fault Time • Fault Output Indication Signal • Automatic Retry Mode or Latched Operation Mode • Shutdown Control • Undervoltage Lockout • 250µs Glitch Filter on the SDFLTCH pin • 8-Pin DIL and SOIC DESCRIPTION The UCC3921 family of negative floating hot swap power managers provides complete 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.
