TPS22971 - On-Resistance Load Switch

General Description

The TPS22971 is a space-saving single-channel load switch with controlled and adjustable Turn-ON slew rate and an integrated Power Good indicator.

Key Features

  • 1 Input Voltage Range (VIN): 0.65 V to 3.6 V.
  • On-Resistance.
  • RON = 6.7 mΩ (typical) at VIN ≥ 1.8 V.
  • RON = 7.2 mΩ (typical) at VIN = 1.05 V.
  • RON = 8.9 mΩ (typical) at VIN = 0.65 V.
  • Maximum Continuous Switch Current (IMAX): 3 A.
  • ON State (IQ): 30 µA (typical) at 3.6 VIN.
  • OFF State (ISD): 1 µA (typical) at 3.6 VIN.
  • Adjustable Slew Rate through CT Pin.
  • Fast Turn-ON ≤ 65 µs at VIN = 1 V.
  • Power Good (PG).
