Frequently Asked Questions
What common-mode voltage range does LT6105IDCB#TRMPBF support for high-side current sensing?
LT6105IDCB#TRMPBF supports a common-mode input range from -0.3 V to 44 V, enabling high-side current sensing across a wide variety of supply rails including 12 V automotive batteries, 24 V industrial buses, and 36 V Li-ion battery packs without requiring the sense resistor to be referenced to ground.
How does the 120 dB typical CMRR of LT6105IDCB#TRMPBF reduce errors in noisy industrial environments?
With 120 dB typical CMRR, LT6105IDCB#TRMPBF rejects common-mode noise by a factor of one million, converting only the differential voltage across the current sense resistor to an output signal. This allows accurate current measurement even when 50 Hz or 60 Hz line noise or PWM switching transients are present on the high-side power rail.
In what package does LT6105IDCB#TRMPBF come, and how does it compare to larger amplifier packages for current sensing?
LT6105IDCB#TRMPBF is housed in a 6-pin SOT-23 (R-PDSO-N6) no-lead package, one of the smallest footprints available for a current sense amplifier. Compared to 8-pin SOIC packages, the SOT-23 saves approximately 50% board area while maintaining all necessary signal, power, and output pins for a complete high-side current sensing circuit.
When is LT6105IDCB#TRMPBF preferred over a shunt-plus-differential-amplifier solution for measuring 24 V bus current?
LT6105IDCB#TRMPBF integrates the high-side sensing function in a single chip optimized for -0.3 V to 44 V common-mode inputs, whereas a discrete shunt plus general-purpose differential amplifier requires careful gain resistor matching to achieve even 60 dB CMRR. The integrated 120 dB CMRR and 0.75 µV offset eliminate the resistor matching effort and reduce measurement error to well below 1% of full-scale current.
