LTC2945IUD#PBF Frequently Asked Questions (FAQ)
-
A 4-layer PCB with a solid ground plane and a separate layer for the sense lines is recommended. Keep the sense lines short and away from noise sources. Use a Kelvin connection to the sense resistor to minimize errors.
-
Calibrate the device by applying a known current to the sense resistor and adjusting the offset and gain registers accordingly. Use the internal calibration registers to store the calibration data.
-
The maximum sense resistor value is limited by the device's input voltage range and the desired current measurement range. Typically, a sense resistor value between 1mΩ and 100mΩ is recommended.
-
Yes, the LTC2945IUD#PBF can measure bidirectional currents. The device has a differential input stage that can measure currents in both directions, allowing it to detect changes in current direction.
-
The LTC2945IUD#PBF has an overcurrent detection feature that can be used to detect overcurrent conditions. The device can be configured to generate an interrupt or reset when an overcurrent condition is detected.
