Product details
Overview
LTC6101VHVBIS5#TRMPBF from Analog Devices is a high-voltage, high-side current sense amplifier in 5-lead TSOT-23 package with HV pinout configuration. It operates from 5V to 100V supply, delivers ≤1mA output current, achieves ≤1µs step response, supports 500mV max input sense voltage, and is specified for –40°C to +85°C operation - used for precision load current monitoring in industrial power supplies.
For engineers reviewing the LTC6101VHVBIS5#TRMPBF datasheet, LTC6101VHVBIS5#TRMPBF pinout, LTC6101VHVBIS5#TRMPBF application, or LTC6101VHVBIS5#TRMPBF equivalent, key selection criteria include high common-mode voltage tolerance (up to 100V), low 300µV max input offset, configurable gain via external RIN/ROUT, PSRR ≥118dB, and SOT-23 HV pinout compatibility with board-level isolation requirements.
Technical Context
The LTC6101VHVBIS5#TRMPBF uses a current-output architecture where VSENSE across an external shunt is converted to proportional output current IOUT = VSENSE/RIN, then translated to ground-referenced voltage via ROUT. Its internal high-impedance sense amplifier forces –IN to match +IN potential, enabling accurate Kelvin sensing.
It features rail-to-rail input stage referenced to V+, supports single-supply operation with V– tied to ground, and maintains stable transconductance over its full 5V–100V supply range. The HV pinout variant provides enhanced creepage/clearance between V+ and –IN pins for high-voltage system safety compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5V to 100V - enables direct monitoring of 48V, 60V, and 96V industrial bus rails without level-shifting circuitry. |
| Max Input Sense Voltage | 500mV - allows use of low-value, low-power-loss shunt resistors (e.g., 5mΩ at 100A) while preserving measurement resolution. |
| Input Offset Voltage (max) | ±450µV - limits worst-case current error to ≤0.9% for 50mΩ/10A sensing (VSENSE = 500mV), critical for battery SOC accuracy. |
| Step Response Time | 1µs (to 2.5V on 5V output step) - supports fast overcurrent detection and shutdown in motor drives and DC-DC converters. |
| PSRR | ≥118dB - rejects supply ripple and noise from high-noise switching rails, ensuring stable output under dynamic load conditions. |
| Output Current Capability | 1mA max - sets practical upper limit for ROUT (e.g., ≤8kΩ for 8V full-scale) and defines minimum load impedance for ADC interfacing. |
| Operating Temperature | –40°C to +85°C - qualified for industrial ambient environments including factory automation and telecom power systems. |
Pinout & Package
Package: 5-lead Plastic TSOT-23 with HV pinout (LTHHD marking), 1mm profile, optimized for high-voltage spacing between V+ and –IN pins per IEC 61000-4-5 and UL 62368-1 creepage requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN | High-side sense input (load-side of shunt) | Connected directly to shunt resistor's load terminal; forms Kelvin sense node for accurate VSENSE acquisition. |
| –IN | High-side sense input (supply-side of shunt) | Tied to shunt's supply-side; internal amplifier forces –IN = +IN, enabling current-derived output current IOUT. |
| V+ | Positive supply input | Accepts 5V–100V; also serves as reference for VSENSE; must be isolated from high-current paths to avoid IR drop errors. |
| OUT | Current output terminal | Sources IOUT = VSENSE/RIN; requires external ROUT to ground to generate analog voltage output VOUT = IOUT × ROUT. |
| V– | Negative supply / ground reference | Typically connected to system ground; establishes ground-referenced output; supports single-supply operation. |
Key Features
| Feature | Design Value |
|---|---|
| High Common-Mode Voltage Operation | Supports direct sensing up to 100V bus voltages without auxiliary biasing or isolation, reducing BOM count and layout complexity. |
| Configurable Gain Architecture | Gain set by external RIN/ROUT ratio (e.g., RIN = 100Ω, ROUT = 10kΩ → gain = 100), enabling flexible full-scale adjustment per application current range. |
| Low Quiescent Supply Current | 230µA typical at 12V - minimizes parasitic loading on monitored rail, critical for always-on battery-backed systems. |
| High PSRR & Low Offset Drift | 118dB PSRR and ±3µV/°C max offset drift ensure stable output across temperature and noisy supply conditions in motor control feedback loops. |
| HV Pinout Layout | Increased spacing between V+ and –IN pins meets reinforced insulation requirements for 300VRMS working voltage applications per IEC 62368-1. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side current sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX40056ASA+T | Fixed-gain (50V/V), 2.7V–60V supply, 1.5µs response, ±120µV offset, 8-pin SOIC package. | Lacks gain configurability and HV pinout; unsuitable for >60V buses or designs requiring layout-level creepage optimization. | Select when fixed gain simplifies design and 60V max supply suffices; verify SOIC creepage meets system safety standards. |
| INA240A1D | Bi-directional output, 2.7V–80V supply, 1.2µs response, ±20µV offset (A1 grade), 8-pin SOIC/SOT-23. | Bi-directional capability adds unnecessary complexity for unidirectional industrial loads; no HV pinout option available. | Prefer for bidirectional motor control or regenerative braking; avoid for high-voltage (>80V) or creepage-critical applications. |
Compared with MAX40056ASA+T and INA240A1D, the LTC6101VHVBIS5#TRMPBF uniquely combines 100V operation, user-configurable gain, HV-specific pinout for safety compliance, and industry-standard TSOT-23 footprint - making it optimal for cost-sensitive, high-reliability industrial power monitoring where voltage headroom and layout safety margins are non-negotiable.

FAQ
What is the absolute maximum supply voltage rating for LTC6101VHVBIS5#TRMPBF?
The LTC6101VHVBIS5#TRMPBF has an absolute maximum total supply voltage (V+ to V–) of 105V, with recommended operating range from 5V to 100V. Exceeding 105V risks permanent damage per Absolute Maximum Ratings table in the datasheet. This rating enables safe deployment in 96V battery systems and 48V/60V industrial rails with margin.
How does the HV pinout configuration of LTC6101VHVBIS5#TRMPBF differ from standard SOT-23 variants?
The LTC6101VHVBIS5#TRMPBF uses the LTHHD-marked HV pinout (V+, –IN, +IN, V–, OUT), which increases physical spacing between V+ and –IN pins compared to standard SOT-23 layouts. This satisfies reinforced insulation requirements for 300VRMS working voltage per IEC 62368-1, unlike standard LTC6101BIS5#TRMPBF (LTBND marking) which lacks this spacing.
Can LTC6101VHVBIS5#TRMPBF be used with a 3.3V microcontroller ADC without level shifting?
Yes - the LTC6101VHVBIS5#TRMPBF outputs a ground-referenced voltage (VOUT = IOUT × ROUT) that can be scaled to 0–3.3V using appropriate RIN/ROUT values (e.g., RIN = 150Ω, ROUT = 5kΩ yields 3.3V at 100mV VSENSE). No level shifter is needed since V– is tied to system ground.
What is the guaranteed input offset voltage specification for LTC6101VHVBIS5#TRMPBF over temperature?
The LTC6101VHVBIS5#TRMPBF (HVB grade) guarantees ±450µV maximum input offset voltage over the full –40°C to +85°C operating range, with ±150µV typical at 25°C. This is confirmed in the LTC6101HV Electrical Characteristics table under "VOS Input Offset Voltage" for HVB grade parts.
Does LTC6101VHVBIS5#TRMPBF support bidirectional current sensing?
No - the LTC6101VHVBIS5#TRMPBF is a unidirectional high-side current sense amplifier. Its output current flows only from OUT to V–, and it cannot resolve negative VSENSE polarity. For bidirectional sensing, Analog Devices recommends the INA240 or similar devices; LTC6101VHVBIS5#TRMPBF is optimized for positive-load-current-only applications like power supply output monitoring.
