High-voltage current sense in a small TSOT-23-5 footprint
The LTC6101HVCIS5#TRMPBF is a single-channel current sense amplifier from Analog Devices designed to measure current on high-side rails up to 100 V without needing a separate bias regulator. It operates from a 5 V to 100 V supply span, drawing only 350 µA quiescent current. The 200 kHz gain-bandwidth product is sufficient to capture average current in a 100 kHz switching converter. Input offset voltage is 400 µV and input bias current is 100 nA. The part is housed in a TSOT-23-5 package and rated for -40°C to 85°C operation.
Active lifecycle — no obsolescence pressure
The LTC6101HVCIS5#TRMPBF carries an Active lifecycle status and is ROHS3 compliant. There is no last-time-buy notice or NRND flag, so it can be specified into new production designs.
