LTC2943CDD#TRPBF Frequently Asked Questions (FAQ)
-
The maximum voltage rating for the VIN pin is 36V, but it's recommended to keep it below 34V for reliable operation.
-
To ensure accurate current measurements, make sure to use a sense resistor with a low temperature coefficient, keep the sense resistor close to the IC, and use a Kelvin connection to the sense resistor.
-
The VCC pin is used to power the internal circuitry of the LTC2943. While it's possible to connect VCC to VIN, it's not recommended as it may affect the accuracy of the current measurements. Instead, use a separate voltage source or a voltage regulator to power the VCC pin.
-
The power consumption of the LTC2943 can be calculated by adding the quiescent current (IQ) to the current consumed by the output stages. The quiescent current is typically around 1.5mA, and the output stage current depends on the output voltage and load current.
-
Yes, the LTC2943 can measure current in both directions. The IC has a bidirectional current sense capability, which allows it to measure both positive and negative currents.
