LTC2851CMS8#PBF Frequently Asked Questions (FAQ)

  • The recommended PCB layout for the LTC2851CMS8#PBF involves keeping the analog and digital grounds separate, using a solid ground plane, and placing the device close to the power supply bypass capacitors. Additionally, it's recommended to use a Kelvin connection for the sense lines and to keep the sense lines as short as possible.

  • To ensure the accuracy of the voltage monitoring function, it's essential to use a high-accuracy voltage reference, such as the internal 0.5% reference of the LTC2851CMS8#PBF. Additionally, the voltage sense lines should be connected as close as possible to the voltage source, and the sense lines should be shielded to prevent noise pickup.

  • The maximum cable length for the I2C bus of the LTC2851CMS8#PBF depends on the clock frequency and the capacitance of the bus. As a general rule, the maximum cable length is around 10-20 meters for a clock frequency of 100 kHz and a bus capacitance of 400 pF. However, it's recommended to use a repeater or a buffer to extend the cable length if necessary.

  • The thermal shutdown feature of the LTC2851CMS8#PBF is designed to protect the device from overheating. If the device exceeds the thermal shutdown threshold, it will shut down and reset when the temperature drops below the thermal hysteresis. To handle thermal shutdown, it's recommended to ensure good thermal design, such as using a heat sink or a thermal pad, and to monitor the device temperature using the thermal monitoring feature.

  • The recommended power-up sequence for the LTC2851CMS8#PBF involves powering up the VCC supply first, followed by the VIO supply. This ensures that the internal voltage regulators are powered up correctly and that the device is properly initialized.
