TPS25985x 4.5 V – 16 V, 0.59-mΩ, 80-A Stackable eFuse with Accurate and Fast Current Monitor
1 Features
- Input operating voltage range: 4.5 V to 16 V
- 20-V absolute maximum
- Withstands negative voltages up to –1 V at output
- Integrated FET with low on-resistance: 0.59 mΩ (typ.)
- Rated for 60-A RMS current and 80-A peak current
- Supports parallel connection of multiple eFuses for higher current support
- Active device state synchronization and load sharing during start-up and steady-state for unlimited scalability
- Robust overcurrent protection
- Adjustable overcurrent threshold (IOCP): 10 A to 60 A with accuracy of ±6% (max.)
- Circuit-breaker response during steady state operation with adjustable transient blanking timer (ITIMER) to support peak currents up to 2 × IOCP
- Adjustable active current limit during start-up (ILIM)
- Robust short-circuit protection
- Fast-trip response (< 200 ns) to output short-circuit events
- Adjustable (2 × IOCP )and fixed thresholds
- Immune to supply line transients — no nuisance tripping
- Precise analog load current monitoring
- ±1.4% accuracy
- > 500-kHz bandwidth
- Fast overvoltage protection (fixed 16.6-V threshold)
- Adjustable output slew rate control (dVdt) for inrush current protection
- Active high enable input with adjustable undervoltage lockout (UVLO)
- Overtemperature Protection (OTP) to ensure FET SOA
- Integrated FET health monitoring and reporting
- Analog die temperature monitor output (TEMP)
- Dedicated fault indication pin (FLT)
- Power Good indication pin (PG)
- Uncommitted general purpose fast comparator
- Small footprint: QFN 4.5-mm × 5-mm, 0.6-mm pitch
- 29-mil clearance between power and GND pins
- 100% Pb Free
