UC2543DW Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the UC2543DW is 10.5V to 15V, with a typical operating voltage of 12V.
  • To ensure proper biasing, connect a 1kΩ resistor between the VCC pin and the VIN pin, and a 2.2kΩ resistor between the VIN pin and ground. This will provide a stable voltage reference for the internal voltage regulator.
  • The UC2543DW can deliver up to 1A of output current per channel, making it suitable for driving high-current loads such as motors and solenoids.
  • To synchronize the outputs of multiple UC2543DW devices, connect the SYNC pin of each device together and drive them with a common clock signal. This will ensure that the outputs of all devices are synchronized.
  • The EN pin is an active-low enable input that allows the user to enable or disable the output stages of the UC2543DW. When the EN pin is low, the output stages are enabled, and when it is high, the output stages are disabled.
