Power Management (PMIC)

smart eFusehot swapreverse blockingcurrent limitWQFN-20

TPS25940ARVCR is a 2.7 V to 18 V smart eFuse with programmable current limiting, voltage protection, controlled output ramping, and true reverse-current blocking for protected power rails.

Best for

  • Protected 2.7 V to 18 V power rails
  • Hot-plug and inrush-controlled loads
  • SSD hold-up and reverse-blocking circuits

Avoid if

  • Input voltage can exceed the stated 20 V absolute maximum without external transient protection
  • DevSleep load current must exceed the 0.67 A typical DevSleep limit

Check before use

  • Thermal dissipation during overload and startup
  • UVLO and OVP resistor-divider thresholds
  • Input and output transient suppression
  • Exposed-pad grounding and PCB thermal layout
