BC372 Frequently Asked Questions (FAQ)

  • The recommended operating voltage range for the BC372 is 2.7V to 5.5V, although it can tolerate up to 6V for short periods.

  • To ensure the BC372 is in a low-power state, make sure the EN (enable) pin is pulled low, and the VIN pin is below 2.7V. Additionally, ensure that the output is not loaded, and the input voltage is within the recommended range.

  • The maximum output current of the BC372 is 200mA, although it's recommended to limit the output current to 150mA for optimal performance and reliability.

  • To handle thermal considerations for the BC372, ensure good thermal conductivity between the device and the PCB, use a heat sink if necessary, and avoid operating the device at high temperatures (above 85°C) for extended periods.

  • The EN (enable) pin on the BC372 is used to enable or disable the device. When the EN pin is pulled high, the device is enabled, and when it's pulled low, the device is disabled and enters a low-power state.
