MCP19118-E/MJ Frequently Asked Questions (FAQs)

  • Microchip recommends a 4-layer PCB with a solid ground plane, and placing the device close to the power source. Decoupling capacitors should be placed as close as possible to the device's power pins. A detailed layout guide can be found in the Microchip application note AN1455.
  • The MCP19118-E/MJ is a highly configurable device. Microchip provides a software tool called the MCP19118 Configurator, which allows users to configure the device for their specific application. The tool can be downloaded from the Microchip website.
  • The maximum output current of the MCP19118-E/MJ is 1.2A per channel. However, the total output current is limited by the device's thermal performance and the PCB's thermal design. Users should ensure that the device is properly heatsinked and the PCB is designed to handle the maximum output current.
  • The MCP19118-E/MJ has a built-in overcurrent protection feature. Users can set the overcurrent threshold using the OCSET pin. When the output current exceeds the set threshold, the device will limit the output current to prevent damage. Users can also implement external overcurrent protection using an external sense resistor and a comparator.
  • The MCP19118-E/MJ is rated for operation up to 125°C. However, the device's performance and reliability may be affected at high temperatures. Users should ensure that the device is properly heatsinked and the PCB is designed to handle high temperatures. Additionally, users should consult the datasheet and application notes for guidance on high-temperature operation.
