Product details
Overview
LTC6101HVCIS5#TRPBF from Analog Devices is a high-voltage, high-side current sense amplifier in 5-lead TSOT-23 package, operating from 5V to 100V supply, featuring 300µV max input offset voltage, 1µs response time, and ±170nA max input bias current. It enables precise shunt-based load current monitoring in automotive battery management and industrial power supplies where common-mode voltage exceeds 60V.
For engineers reviewing the LTC6101HVCIS5#TRPBF datasheet, LTC6101HVCIS5#TRPBF pinout, LTC6101HVCIS5#TRPBF application, or LTC6101HVCIS5#TRPBF equivalent, key selection criteria include high-voltage common-mode tolerance (up to 100V), low-offset operation at –40°C to +85°C, gain configuration via external RIN/ROUT, and compatibility with ground-referenced ADC interfaces.
Technical Context
The LTC6101HVCIS5#TRPBF uses a current-output architecture where output current IOUT = VSENSE/RIN, enabling accurate level-shifting of high-side sense signals to ground-referenced voltage outputs via ROUT. Its internal amplifier forces –IN to track +IN, eliminating common-mode dependence on RIN placement.
It supports configurable gain (e.g., 20×, 50×, 100×) through discrete resistor networks, delivers 1mA max output current, and maintains 118dB min PSRR across 5V–100V supply range. The device operates over –40°C to +85°C with guaranteed specifications, including 500mV max input sense voltage and 140kHz signal bandwidth at 200µA load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5V to 100V - supports direct connection to 48V, 72V, and 96V industrial bus rails without level-shifting circuitry. |
| Input Offset Voltage | ±400 µV max - enables use of larger sense resistors for sub-10mA current resolution while limiting power loss. |
| Response Time | 1 µs - provides fast detection of overcurrent events for real-time load protection in motor drives and DC-DC converters. |
| Input Bias Current | 170 nA max - minimizes error contribution from PCB trace resistance and allows Kelvin sensing with minimal correction. |
| PSRR | 118 dB min - rejects supply ripple and noise in high-noise environments such as automotive alternator systems. |
| Operating Temperature | –40°C to +85°C - qualified for under-hood automotive and outdoor industrial applications without derating. |
| Output Current | 1 mA max - sufficient to drive 10kΩ ROUT for 10V full-scale output or interface directly with SAR ADC reference inputs. |
Pinout & Package
Package: 5-lead TSOT-23 (ThinSOT™), 1mm profile, HV-optimized creepage/clearance spacing per LTC6101HV family requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN | High-side sense input (non-inverting) | Connected to load side of shunt resistor; establishes reference for differential sense voltage measurement. |
| –IN | High-side sense input (inverting) | Driven to match +IN potential by internal amplifier; tied to V+ via RIN to set transconductance gain. |
| V+ | Positive supply input | Supplies operating current; also serves as high-side common-mode reference for sense inputs. |
| V– | Negative supply / ground reference | Provides return path for output current and sets ground reference for VOUT = IOUT × ROUT. |
| OUT | Current output terminal | Sources IOUT = VSENSE/RIN; requires external ROUT to ground to generate analog voltage output. |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage operation | 100V max supply enables direct monitoring of 48V/72V/96V battery stacks and telecom power systems without auxiliary supplies. |
| Configurable gain | Gain set by external RIN/ROUT (e.g., 100× with RIN = 100Ω, ROUT = 10kΩ) avoids fixed-gain limitations and optimizes dynamic range per application. |
| Low quiescent current | 230 µA typical at 12V - reduces self-heating error and extends runtime in always-on battery monitoring circuits. |
| Kelvin-compatible inputs | Separate +IN/–IN pins support 4-wire shunt connections to eliminate PCB trace resistance errors in high-current paths. |
| Robust output stage | 1mA continuous output current with indefinite short-circuit tolerance to V– ensures reliability during transient fault conditions. |

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 50V max supply; 12-bit integrated ADC; SPI interface; no external RIN/ROUT configuration. | Requires digital interface and firmware support; lacks analog output flexibility for legacy µP ADCs. | Select when digital output and built-in diagnostics outweigh need for analog configurability and ultra-low offset. |
| INA240A1QDRQ1 | 4V–80V supply; 100µV max offset; 100kHz bandwidth; SOIC-8 package; AEC-Q100 qualified. | Lower voltage rating limits use in >80V systems; automotive qualification adds cost for non-automotive designs. | Select for automotive-grade production where 80V ceiling is acceptable and AEC-Q100 compliance is mandatory. |

FAQ
What is the absolute maximum supply voltage for LTC6101HVCIS5#TRPBF?
The absolute maximum total supply voltage (V+ to V–) for LTC6101HVCIS5#TRPBF is 105V, with recommended operating range from 5V to 100V. Exceeding 105V risks permanent damage per Absolute Maximum Ratings. This rating enables safe deployment in 96V battery systems and telecom -48V with positive headroom.
How does LTC6101HVCIS5#TRPBF achieve high common-mode rejection without a dedicated reference pin?
LTC6101HVCIS5#TRPBF achieves high common-mode rejection through its current-output architecture and internal feedback loop that forces –IN to track +IN. This eliminates dependence on external resistor matching and delivers 118dB PSRR without requiring a separate reference or matched resistor network.
Can LTC6101HVCIS5#TRPBF be used with a 3.3V microcontroller ADC?
Yes - LTC6101HVCIS5#TRPBF generates a ground-referenced output voltage (VOUT = IOUT × ROUT). By selecting ROUT to scale VSENSE × (ROUT/RIN) to 0–3.3V full-scale, it directly interfaces with 3.3V ADCs without level-shifting circuitry or additional op amps.
What is the guaranteed temperature range for LTC6101HVCIS5#TRPBF?
LTC6101HVCIS5#TRPBF is specified over –40°C to +85°C, with all electrical parameters guaranteed across this range. It is part of the HVC grade (High Voltage, Commercial/Industrial), distinct from H grade (–40°C to +125°C) and C grade (0°C to +70°C).
Does LTC6101HVCIS5#TRPBF require Kelvin connection for accurate measurement?
Kelvin connection is strongly recommended for accurate measurement, especially at load currents above 5A. The separate +IN and –IN pins enable true 4-wire sensing; using shared traces introduces voltage drop errors that degrade offset performance - particularly critical given the ±400µV max offset specification of LTC6101HVCIS5#TRPBF.
