A capacitor to GND on the CT pin sets the slew rate, and the higher the Capacitor the higher the slew rate. Rise times are shown below.The following equation can be used to estimate the rise time for different VIN and CT capacitors:

tR = (0.3418VIN + 0.1036) × CT + 14.064VIN + 12.255

where

  • tR = Rise time in µs.
  • VIN = Input voltage in V.
  • CT = CT Capacitor in pF.

Evaluation board

TPS22995EVM — TPS22995 evaluation module for 5-V 20-mΩ 4-A load switch with adjustable rise time

The TPS22995 evaluation module (EVM) is an assembled and tested circuit for evaluating the TPS22995RZF and TPS22995RZG load switches. The TPS22995EVM allows the user to apply different input voltages (0.4 V to 5.5 V) under different loading conditions (0 A to 3.5 A) to the TPS22995 devices.
