TPS22932B - Ultralow rON Load Switch

Description

The TPS22932B device is a low rON load switch with controlled turnon.

The device contains a P-channel MOSFET that can operate over an input voltage range of 1.1 V to 3.6 V.

The switch is controlled by eight patterns of 3-bit input.

Features

  • 1 Input Voltage: 1.1 V to 3.6 V.
  • Ultralow ON-Resistance.
  • rON = 55 mΩ at VIN = 3.6 V.
  • rON = 65 mΩ at VIN = 2.5 V.
  • rON = 75 mΩ at VIN = 1.8 V.
  • rON = 115 mΩ at VIN = 1.2 V.
  • 500-mA Maximum Continuous Switch Current.
  • Quiescent Current < 1 μA.
  • Shutdown Current < 1 μA.
  • Low Control Threshold Allows Use of 1.2-V, 1.8-V, 2.5-V, and 3.3-V Logic.
  • Configurable Enable Logic.
  • Controlled Slew Rate to Avoi.
