TPS22945DCKR Frequently Asked Questions (FAQs)

  • The maximum current rating of the TPS22945DCKR is 5A per channel, with a total current limit of 10A for both channels combined.
  • To ensure proper thermal management, it is recommended to provide a heat sink or thermal pad to the device, and to keep the ambient temperature below 85°C. Additionally, the device should be mounted on a multi-layer PCB with thermal vias to dissipate heat effectively.
  • The EN (enable) pin is used to enable or disable the device. When the EN pin is high, the device is enabled and the switches are turned on. When the EN pin is low, the device is disabled and the switches are turned off.
  • The TPS22945DCKR can be configured for high-side or low-side switching by connecting the VIN pin to the positive supply rail for high-side switching, or to the negative supply rail for low-side switching.
  • The minimum input voltage required for the TPS22945DCKR to operate is 2.7V, although the recommended operating range is 3.0V to 5.5V.
