Frequently Asked Questions
What supply voltage range does the LT6108IMS8-1#PBF support, and how does this affect system design?
The LT6108IMS8-1#PBF operates across a 2.7 V to 18 V supply range, making it compatible with single-cell Li-ion batteries at 3.6 V as well as 12 V and 15 V bus rails. This wide range allows designers to use a single part across multiple product variants without redesigning the sense circuit, reducing BOM complexity in power management systems.
How does the 125 dB CMRR of the LT6108IMS8-1#PBF benefit high-side current sensing designs?
With 125 dB common-mode rejection ratio, the LT6108IMS8-1#PBF suppresses supply-rail noise and ground bounce by more than 100,000:1, ensuring that the differential voltage across the shunt resistor — typically only a few millivolts — is measured accurately even when the common-mode voltage swings up to 18 V. This high CMRR is critical in motor-drive and battery-pack applications where bus transients are frequent.
When is the LT6108IMS8-1#PBF a strong candidate over a discrete op-amp plus comparator solution for overcurrent protection?
The LT6108IMS8-1#PBF integrates a current-sense amplifier, comparator, and 400 mV voltage reference into a single MSOP-8 package occupying roughly 15 mm², replacing at least 3 discrete ICs and cutting board area by 50% or more. The internal reference also eliminates the ±1% tolerance stack-up of an external reference, giving a tighter trip-point accuracy — ideal for space-constrained servers and portable medical devices.
