TPS22945 - Low-input-voltage Current-limited Load Switches

Download the TPS22945 datasheet PDF. This datasheet also covers the TPS22941 variant, as both devices belong to the same low-input-voltage current-limited load switches family and are provided as variant models within a single manufacturer datasheet.

Description

The TPS22941/2/3/4/5 load switches provide protection to systems and loads in high-current conditions.

The devices contain a 0.4-Ω currentlimited P-channel MOSFET that can operate over an input voltage range of 1.62 V to 5.5 V.

Current is prevented from flowing when the MOSFET is off.

Features

  • 1 Input Voltage Range: 1.62 V to 5.5 V.
  • Low ON resistance.
  • rON = 0.4 Ω at VIN = 5.5 V.
  • rON = 0.5 Ω at VIN = 3.3 V.
  • rON = 0.6 Ω at VIN = 2.5 V.
  • rON = 0.8 Ω at VIN = 1.8 V.
  • Minimum Current Limit: 40 mA or 100 mA.
  • Undervoltage Lockout (UVLO).
  • Thermal Shutdown.
  • Shutdown Current < 1 μA.
  • Fast Current Limit Response Time.
  • Fault Blanking.
  • Auto Restart.
  • 1.8-V Compatible Control In.
