MCP19119-E/MQ Frequently Asked Questions (FAQs)

  • The maximum output current of the MCP19119-E/MQ is 1.5A per channel, with a total maximum output current of 3A for both channels.
  • The MCP19119-E/MQ can be configured for synchronous or asynchronous operation by setting the SYNC pin high or low, respectively. Synchronous operation allows for simultaneous switching of both channels, while asynchronous operation allows for independent switching of each channel.
  • The EN (Enable) pin is used to enable or disable the output stages of the MCP19119-E/MQ. When the EN pin is high, the output stages are enabled, and when it is low, the output stages are disabled.
  • The switching frequency of the MCP19119-E/MQ can be adjusted by connecting a resistor (RT) between the RT pin and ground. The switching frequency is inversely proportional to the value of RT.
  • The FLT (Fault) pin is an open-drain output that indicates when a fault condition occurs, such as overcurrent or overtemperature. The FLT pin can be connected to a microcontroller or other logic circuit to detect and respond to fault conditions.
