TPS25985数据手册TI中文资料规格书

特性 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 ultra-low on-resistance: 0.59 mΩ (typ.)
• Rated for continuous current of 55 A and peak current of 70 A
• Supports parallel connection of multiple eFuses for higher current support
• Active device state synchronization and load sharing during start-up and steady-state

• Robust overcurrent protection
• Adjustable overcurrent threshold (IOCP): 10 A to 60 A with accuracy of ±5%
• Circuit-breaker response during steady state operation with adjustable transient overcurrent 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 threshold (2 × IOCP)
• Immune to supply line transients — no nuisance tripping

• Precise load current monitoring
• 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)
