TPS22901 - ON-Resistance Load Switch

General Description

The TPS22901, TPS22902, and TPS22902B are small, low ON-resistance (rON) load switches with a controlled turnon.

These devices contain a P-channel MOSFET that operates over an input voltage range of 1.0 V to 3.6 V.

Key Features

  • 1 Integrated P-Channel Load Switch.
  • Low Input Voltage: 1 V to 3.6 V.
  • ON-Resistance (Typical Values).
  • rON = 78 mΩ at VIN = 3.6 V.
  • rON = 93 mΩ at VIN = 2.5 V.
  • rON = 109 mΩ at VIN = 1.8 V.
  • rON = 146 mΩ at VIN = 1.2 V.
  • 500 mA Maximum Continuous Switch Current.
  • Quiescent Current: 82 nA at 1.8 V.
  • Shutdown Current: 44 nA at 1.8 V.
  • Low Control Input Thresholds Enable Use of 1.2-V, 1.8-V, 2.5-V, and 3.3-V L.
