Product details
Overview
LTC6101HVCIS5#TRMPBF from Analog Devices is a high-voltage, high-side current sense amplifier in 5-lead TSOT-23 package, delivering 1 µs step response, ±300 µV max input offset voltage, and operation from 5 V to 100 V supply. It converts shunt voltage (up to 500 mV) into ground-referenced output current for precision battery monitoring and industrial power rail sensing.
For engineers reviewing the LTC6101HVCIS5#TRMPBF datasheet, LTC6101HVCIS5#TRMPBF pinout, LTC6101HVCIS5#TRMPBF application, or LTC6101HVCIS5#TRMPBF equivalent, key selection criteria include high common-mode voltage tolerance (105 V abs max), low quiescent current (350 µA at 100 V), –40°C to 85°C specified temperature range, and configurable gain via external RIN/ROUT.
Technical Context
The LTC6101HVCIS5#TRMPBF uses a feedback-controlled transconductance architecture: its internal amplifier forces –IN to match +IN potential, enabling precise current derivation IOUT = VSENSE/RIN. This eliminates direct high-side voltage measurement while maintaining accuracy under high common-mode conditions.
It supports unidirectional sensing only, with output current sourced from OUT pin into an external ROUT to generate VOUT = IOUT × ROUT. PSRR exceeds 118 dB across 5 V–100 V supply range, and input bias current remains ≤170 nA - critical for minimizing error with high-value RIN configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5 V to 100 V - enables direct monitoring of 48 V, 60 V, and 96 V industrial and automotive power rails without level-shifting circuitry. |
| Input Offset Voltage | ±300 µV max - allows use of small shunt resistors (e.g., 5 mΩ) while maintaining <1% error at 1 A load, reducing power loss and thermal drift. |
| Step Response Time | 1 µs (to 2.5 V on 5 V output step) - supports fast overcurrent detection and real-time load transient analysis in protection circuits. |
| Power Supply Rejection | 118 dB min - ensures stable output despite ripple or noise on high-voltage supply lines, critical in switching power systems. |
| Supply Current | 350 µA typical at 100 V - enables always-on current monitoring in energy-constrained applications like remote battery telemetry. |
| Input Sense Range | 0–500 mV full-scale - accommodates wide dynamic current ranges (e.g., 1 mA to 100 A) using appropriate shunt sizing and gain configuration. |
| Operating Temperature | –40°C to 85°C specified - validated for deployment in industrial control cabinets and automotive under-hood environments. |
Pinout & Package
Package: 5-lead TSOT-23 (ThinSOT™), 1 mm profile, HV-optimized spacing per Absolute Maximum Rating of 105 V (V+ to V–).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN | High-side sense input (non-inverting) | Connected directly to load side of shunt resistor; establishes reference point for differential sense voltage measurement. |
| –IN | Feedback input (inverting) | Tied to V+ via RIN; internal amplifier drives this node to match +IN, defining transconductance IOUT = VSENSE/RIN. |
| V+ | Positive supply input | Supplies operating current; also serves as common-mode reference for high-side sensing - must connect to more positive side of shunt to exclude IC supply current from measurement. |
| OUT | Current output terminal | Sources proportional current (IOUT) to external ROUT; output voltage VOUT = IOUT × ROUT is ground-referenced and ADC-ready. |
| V– | Negative supply / ground reference | Typically connected to system ground; defines output voltage reference and completes current path for OUT pin. |
Key Features
| Feature | Design Value |
|---|---|
| High common-mode voltage operation | Supports sensing up to 100 V supply with 105 V absolute maximum rating - eliminates need for isolated amplifiers in 48 V/60 V systems. |
| Configurable gain via external resistors | RIN and ROUT set transconductance and output scaling independently - enables flexible optimization for resolution vs. dynamic range. |
| Low input bias current | ≤170 nA max - minimizes error when using large RIN values (>10 kΩ) for ultra-low-current sensing (e.g., standby leakage monitoring). |
| Fast transient response | 1 µs rise time with 100 mV input step - enables real-time detection of short-circuit events and load surges before damage occurs. |
| High PSRR and low offset drift | 118 dB PSRR + ±3 µV/°C max offset drift - maintains accuracy across wide temperature and noisy supply conditions in motor drives and SMPS. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side current sense amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX40056ASA+T | Fixed gain (50 V/V), 2.7 V–60 V supply, 1.5 µs response, ±120 µV offset | Lower voltage range limits use in >60 V systems; fixed gain reduces design flexibility for multi-range BMS | Select when simplicity and lowest offset are prioritized over voltage range and configurability |
| INA286AIDR | 2.7 V–18 V supply, 1000 V/V fixed gain, 1.2 µs response, ±150 µV offset | Not rated for >18 V - requires external level-shifting for 48 V+ rails; higher gain reduces dynamic range for high-current sensing | Choose for cost-sensitive, low-voltage (<24 V) industrial sensors where board space permits isolation components |

FAQ
What is the absolute maximum supply voltage rating for the LTC6101HVCIS5#TRMPBF?
The LTC6101HVCIS5#TRMPBF has an absolute maximum total supply voltage (V+ to V–) rating of 105 V, with operational range specified from 5 V to 100 V. This rating enables safe deployment in 48 V, 60 V, and 96 V systems with sufficient margin against transients and ripple. Exceeding 105 V risks permanent device damage per Analog Devices' Absolute Maximum Ratings table.
How does the LTC6101HVCIS5#TRMPBF achieve high-side current sensing without isolation components?
The LTC6101HVCIS5#TRMPBF achieves high-side sensing using a patented feedback architecture: its internal amplifier forces the –IN pin to track the +IN pin potential, causing current IOUT = VSENSE/RIN to flow through the OUT pin. Since VSENSE is developed across the shunt and referenced to V+, but IOUT is sourced to ground via ROUT, the output becomes ground-referenced - eliminating need for optocouplers or isolated supplies in the LTC6101HVCIS5#TRMPBF design.
What is the guaranteed input offset voltage specification for the LTC6101HVCIS5#TRMPBF over temperature?
The LTC6101HVCIS5#TRMPBF guarantees ±300 µV maximum input offset voltage over its specified temperature range of –40°C to 85°C. This value is confirmed in the "ELECTRICAL CHARACTERISTICS (LTC6101HV)" table under VOS for the HVC grade. The offset drift is ±3 µV/°C max, ensuring predictable error contribution across the full operating range.
Can the LTC6101HVCIS5#TRMPBF be used in bidirectional current sensing applications?
No, the LTC6101HVCIS5#TRMPBF is designed exclusively for unidirectional (high-side) current sensing. Its internal architecture sources current only from the OUT pin and does not support reverse current flow or negative VSENSE interpretation. For bidirectional applications, Analog Devices recommends the LTC6102 or LTC6104 families, which feature dual-output or rail-to-rail input capability not present in the LTC6101HVCIS5#TRMPBF.
What package type and marking code does the LTC6101HVCIS5#TRMPBF use?
The LTC6101HVCIS5#TRMPBF uses the 5-lead plastic TSOT-23 (ThinSOT™) package with HV-optimized pin spacing, and carries the top-side laser marking code "LTBSZ". This marking is verified in the "ORDER INFORMATION" section of the datasheet and distinguishes it from standard LTC6101 variants (e.g., LTBND) and MSOP-packaged versions.
