TPS259472ARPWR +BOM

2.7-V to 23-V, 28-mΩ, 5.5-A eFuse with integrated reverse polarity protection

TPS259472ARPWR Information

Description

The TPS259472ARPWR is a high-performance, wide-input-voltage-range eFuse from Texas Instruments (TI). It features integrated reverse polarity protection, making it suitable for applications requiring robust power management and protection. This device offers a wide operating input voltage range of 2.7V to 23V, withstanding negative voltages up to 15V. The eFuse has low on-resistance (28.3mΩ typ.) and provides ideal diode operation with true reverse current blocking. The TPS259472ARPWR also features fast overvoltage protection, adjustable overvoltage lockout, and active current limit or circuit-breaker options. It is suitable for various applications such as power MUX/ORing, adapter input protection, USB PD protection, and more.

Features

The TPS259472ARPWR features:

  • Wide operating input voltage range: 2.7 V to 23 V
  • Integrated back-to-back FETs with low on-resistance (28.3 mOhm typ.)
  • Ideal diode operation with true reverse current blocking
  • Fast overvoltage protection with pin-selectable threshold and 5 ms response time
  • Adjustable overvoltage lockout (OVLO) with 1.2 ms response time
  • Overcurrent protection with load current monitor output (ILM)
  • Active current limit or circuit-breaker options
  • Adjustable threshold for ILM from 0.5 A to 6 A
  • Output load current monitor accuracy: ±16% (IOUT ≥ 1 A)

These features make it suitable for power MUX/ORing, adapter input protection, USB PD protection, and other applications where reliable power management is required.
