Product details
Overview
LTC6101HVCHS5#TRMPBF from Analog Devices is a high-voltage, high-side current sense amplifier in 5-lead TSOT-23 package, delivering 1μs step response, ±300μV max input offset voltage, and operation from 5V to 100V supply. It converts shunt voltage into ground-referenced output current for precision monitoring in automotive battery management and industrial power supplies.
For engineers reviewing the LTC6101HVCHS5#TRMPBF datasheet, LTC6101HVCHS5#TRMPBF pinout, LTC6101HVCHS5#TRMPBF application, or LTC6101HVCHS5#TRMPBF equivalent, key selection criteria include high common-mode voltage tolerance (105V abs max), low quiescent current (350μA at 100V), –40°C to 125°C operating range, and configurable gain via external RIN/ROUT.
Technical Context
The LTC6101HVCHS5#TRMPBF uses a feedback-controlled transconductance architecture: its internal amplifier forces –IN to match +IN potential, enabling precise VSENSE measurement across an external shunt. Output current IOUT = VSENSE/RIN is sourced from the OUT pin, independent of V+ common-mode level.
This architecture supports wide dynamic range sensing-up to 500mV full-scale input-with minimal error contribution from PSRR (118dB min) and input bias current (170nA max). The device operates with no internal gain-setting resistors, allowing flexible, application-specific scaling via external RIN and ROUT.

FAQ
What is the absolute maximum supply voltage rating for LTC6101HVCHS5#TRMPBF?
The absolute maximum total supply voltage (V+ to V–) for LTC6101HVCHS5#TRMPBF is 105V, as specified in the Absolute Maximum Ratings table. Operation beyond this limit risks permanent damage. The device is rated for continuous operation from 5V to 100V, making it suitable for 48V and 96V industrial and automotive systems without derating.
How does LTC6101HVCHS5#TRMPBF achieve high-side current sensing without a level-shifting circuit?
LTC6101HVCHS5#TRMPBF achieves high-side sensing using a transconductance architecture that references the output current to V– (ground), regardless of V+ common-mode voltage. By forcing –IN to match +IN potential and sinking IOUT = VSENSE/RIN through the OUT pin to V–, it delivers a ground-referenced analog signal without active level shifting or isolation components.
Can LTC6101HVCHS5#TRMPBF be used with a 3.3V microcontroller ADC?
Yes - LTC6101HVCHS5#TRMPBF can interface directly with a 3.3V microcontroller ADC by selecting ROUT to limit VOUT to ≤3.3V. For example, with VSENSE = 500mV full scale and RIN = 100Ω, IOUT = 5mA; choosing ROUT = 660Ω yields VOUT = 3.3V. The device's 1mA max output current and 8V max output voltage ensure safe operation within this constraint.
What is the minimum detectable load current using LTC6101HVCHS5#TRMPBF with a 50mΩ shunt resistor?
With a 50mΩ shunt and ±300μV max input offset, the minimum resolvable load current is approximately 6mA (300μV ÷ 50mΩ). This assumes gain configuration and ADC resolution allow detection of the resulting ~300mV output swing. At 125°C, offset may increase slightly, but the –40°C to 125°C guaranteed spec ensures consistent performance across automotive and industrial thermal profiles.
Does LTC6101HVCHS5#TRMPBF require external compensation capacitors for stability?
No - LTC6101HVCHS5#TRMPBF is internally compensated and stable with standard RIN/ROUT configurations. Stability is maintained across the full 5–100V supply range and up to 1000pF capacitive load, as verified in the Step Response and Load Capacitance test data. External capacitors are only needed for filtering or noise reduction, not for loop stability.
