LTC2928CG#TRPBF Frequently Asked Questions (FAQs)

  • The recommended layout and placement for the LTC2928CG involves keeping the input and output traces short and away from noise sources, using a solid ground plane, and placing the device close to the power supply bypass capacitors. A 4-layer PCB with a solid ground plane is recommended. Refer to the application note AN137 for more details.
  • To ensure the accuracy of the voltage monitoring function, it is essential to use a high-accuracy voltage reference, such as the internal 1.2V reference of the LTC2928CG. Additionally, the input voltage range should be within the specified range, and the input impedance should be high enough to prevent loading effects. It is also recommended to use a low-noise, low-impedance power supply and to minimize noise coupling into the input traces.
  • The maximum cable length for the I2C interface depends on the specific application and the capacitance of the cable. As a general rule, the total capacitance of the bus should not exceed 400pF. For a typical I2C cable with a capacitance of 10pF/ft, the maximum cable length would be around 40ft. However, it is recommended to use a repeater or a buffer if the cable length exceeds 10ft to ensure reliable operation.
  • The power-up sequence for the LTC2928CG involves applying the power supply voltage (VCC) before the input voltage (VIN). The device will power up correctly as long as VCC is applied before VIN. It is also recommended to add a power-up reset circuit to ensure that the device is properly reset during power-up.
  • The thermal derating for the LTC2928CG is typically 1.5°C/W above 25°C. This means that the maximum power dissipation will decrease by 1.5°C/W for every degree above 25°C. It is essential to ensure that the device is operated within the specified thermal limits to prevent overheating and ensure reliable operation.
