Overview

The TPS25947xx family of eFuses is a highly integrated circuit protection and power management solution in a small package. The devices provide multiple protection modes using ver.

  • Wide operating input voltage range: 2.7 V to 23 V - 28-V absolute maximum - Withstands negative voltages up to - 15 V
  • Integrated back-to-back FETs with low OnResistance: RON = 28.3 mΩ (typ)
  • Ideal diode operation with true reverse current blocking
  • Fast overvoltage protection - Overvoltage clamp (OVC) with pin-selectable threshold (3.8 V, 5.7 V, 13.8 V) and 5-μs (typ) response time OR - Adjustable overvoltage lockout (OVLO) with 1.2-μs (typ) response time
  • Overcurrent protection with load current monitor output (ILM) - Active current limit OR circuit-breaker options - Adjustable threshold (ILIM) 0.5 A - 6 A
  • ±10% accuracy for ILIM > 1 A - Adjustable transient blanking timer (ITIMER) to allow peak currents up to 2 x ILIM - Output load current monitor accuracy: ±6% (IOUT ≥ 1 A)
  • Fast-trip response for short-circuit protection - 500-ns (typ) response time - Adjustable (2 x ILIM) and fixed thresholds
  • Active high enable input with adjustable undervoltage lockout threshold (UVLO)
  • Adjustable output slew rate control (dVdt)
  • Overtemperature protection
