• What is the maximum current rating of the TPS22920YZPRB?
  The maximum current rating of the TPS22920YZPRB is 2A per channel, with a total current limit of 4A for both channels combined.
• How do I ensure proper thermal management for the TPS22920YZPRB?
  To ensure proper thermal management, it is recommended to provide a thermal pad on the PCB, use a heat sink if necessary, and ensure good airflow around the device. The junction-to-ambient thermal resistance (RθJA) is 30°C/W.
• What is the purpose of the EN pin on the TPS22920YZPRB?
  The EN (enable) pin is used to enable or disable the device. When EN is high, the device is enabled, and when EN is low, the device is disabled and in a low-power state.
• How do I configure the TPS22920YZPRB for active-high or active-low logic?
  The TPS22920YZPRB can be configured for active-high or active-low logic by connecting the FLT pin to VCC or GND, respectively. Active-high logic is the default configuration.
• What is the purpose of the FLT pin on the TPS22920YZPRB?
  The FLT (fault) pin is an open-drain output that indicates an overcurrent or overtemperature fault condition. It can be used to trigger an interrupt or reset in the system.
