Product details
Overview
LTC6101HVBHS5#TRPBF from Analog Devices is a high-voltage, high-side current sense amplifier in 5-lead TSOT-23 package, designed for unidirectional sensing across 5V–100V supply rails with ±450 µV max input offset voltage, 1 µs step response, and 118 dB min PSRR. It enables precise load current monitoring in automotive battery management and industrial power supplies using external RIN/ROUT resistors to configure gain and output voltage.
For engineers reviewing the LTC6101HVBHS5#TRPBF datasheet, LTC6101HVBHS5#TRPBF pinout, LTC6101HVBHS5#TRPBF application, or LTC6101HVBHS5#TRPBF equivalent, this page delivers verified specifications, thermal-grade packaging (–40°C to 125°C), SOT-23 HV pinout validation, and real-world current-sense design context - all grounded in Analog Devices' official LTC6101HV datasheet Rev I.
Technical Context
The LTC6101HVBHS5#TRPBF implements a high-impedance current-output architecture where VSENSE across an external shunt is converted to IOUT = VSENSE/RIN, then translated to ground-referenced VOUT = IOUT × ROUT. Its internal sense amplifier forces –IN to match +IN potential, enabling Kelvin-connected shunt measurement independent of common-mode voltage up to 100V.
This device operates with no internal gain-setting components - all signal conditioning is resistor-defined. Its 170 nA max input bias current and 350 µA supply current at 12V support low-power, high-accuracy sensing without compromising bandwidth (140 kHz typical) or DC precision (±450 µV offset, ±3 µV/°C drift).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5V to 100V - supports direct connection to high-voltage bus rails without level-shifting or auxiliary supplies. |
| Input Offset Voltage | ±450 µV max - limits minimum resolvable sense voltage to ~9 mV when using 100 Ω RIN, enabling accurate sub-ampere current detection. |
| Step Response Time | 1 µs (to 2.5V on 5V output step) - provides fast overcurrent warning for protection circuits in motor drives and DC-DC converters. |
| Power Supply Rejection | 118 dB min - rejects supply ripple and noise, preserving accuracy in noisy 12V/24V/48V systems with switching regulators. |
| Output Current Capability | 1 mA max - sets upper bound on ROUT selection (e.g., ≤8 kΩ for 8V VOUT max) while maintaining linearity. |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive and industrial environments without derating. |
| Input Sense Range | 500 mV full-scale - allows use of low-value, low-power shunts (e.g., 5 mΩ @ 100 A) while retaining >60 dB dynamic range. |
Pinout & Package
Package: 5-lead TSOT-23 (ThinSOT™), 1 mm profile, HV pinout variant (LTHHD marking), rated for 105V absolute maximum supply voltage with enhanced creepage/clearance spacing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN | High-side shunt voltage reference | Connected directly to load side of sense resistor; defines common-mode input point for Kelvin sensing. |
| –IN | Feedback node for internal amplifier | Driven to same potential as +IN via internal loop; tied to V+ through RIN to generate IOUT. |
| V+ | Positive supply input | Accepts 5V–100V; supply current drawn here; placement relative to shunt determines whether LTC6101 current is included in measurement. |
| OUT | Current output terminal | Sources IOUT = VSENSE/RIN; requires external ROUT to ground to produce VOUT = IOUT × ROUT. |
| V– | Negative supply / ground reference | Typically connected to system ground; establishes 0 V reference for VOUT and defines output compliance range. |
Key Features
| Feature | Design Value |
|---|---|
| Configurable gain via RIN/ROUT | Enables precise scaling (e.g., 250 mV/A or 2.5 V/A) without trimming or calibration - supports multi-range designs with dual amplifiers. |
| Low 350 µA supply current at 12V | Reduces self-heating and system power overhead in always-on battery monitors and energy metering applications. |
| 118 dB PSRR | Maintains <0.001% gain error under 1 Vpp supply ripple - critical for stable readings in buck converter feedback paths. |
| 1 µs transient response | Supports real-time overcurrent shutdown in <2 µs total loop time when paired with comparator (e.g., LTC1540). |
| –40°C to 125°C operation | Eliminates need for external temperature compensation in EV charging modules and industrial PLC power stages. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage, high-side current sense amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX40056ASA+T | Fixed 50 V/V gain, 2.7V–65V supply, 1.5 µs response, ±125 µV offset | Requires no external resistors but lacks gain flexibility; limited to lower voltage rails | Select when board space is constrained and fixed-gain suffices; not suitable for 100V systems. |
| INA240A1DGNR | Bi-directional output, 2.7V–80V supply, 1.2 µs response, ±20 µV offset | Supports regenerative braking current sensing; higher precision but higher cost and larger 8-pin VSSOP package | Choose for bidirectional motor control or when <±20 µV offset is mandatory; adds complexity for unidirectional use. |

FAQ
What is the maximum supply voltage rating for the LTC6101HVBHS5#TRPBF?
The LTC6101HVBHS5#TRPBF has an absolute maximum supply voltage of 105V between V+ and V– pins, with continuous operation specified from 5V to 100V. This rating is validated per Analog Devices' LTC6101HV datasheet Rev I, Table "Absolute Maximum Ratings", and applies to the HVB grade with –40°C to 125°C temperature qualification. Exceeding 105V risks permanent damage.
How does the LTC6101HVBHS5#TRPBF achieve high common-mode rejection without a dedicated reference pin?
The LTC6101HVBHS5#TRPBF uses a servo-controlled –IN input that tracks +IN potential, forcing the internal amplifier to operate with near-zero differential input voltage. This architecture inherently rejects common-mode variations up to 100V while maintaining 118 dB PSRR - eliminating need for external references or matched resistor networks required by conventional difference amplifiers.
Can the LTC6101HVBHS5#TRPBF be used with a single 5V supply?
Yes - the LTC6101HVBHS5#TRPBF functions with a minimum 5V supply, as confirmed in its "Supply Voltage Range" specification (5V to 100V). At 5V, it delivers 1 µs step response and maintains ±450 µV max offset. However, VOUT is limited to 3V max per datasheet Figure 6, requiring appropriate ROUT sizing for downstream ADC compatibility.
What is the purpose of the HV pinout configuration in the LTC6101HVBHS5#TRPBF?
The HV pinout (marked LTHHD) in the LTC6101HVBHS5#TRPBF increases creepage and clearance between V+ and adjacent pins - critical for reliable operation at 100V bus voltages. Unlike standard SOT-23 variants, this layout prevents arcing or leakage in high-humidity or dusty industrial environments, as defined in Analog Devices' tape-and-reel documentation for LTC6101VHVBHS5#TRPBF variants.
Does the LTC6101HVBHS5#TRPBF require external capacitors for stability?
No external compensation capacitors are required for basic operation. The LTC6101HVBHS5#TRPBF is internally compensated and remains stable driving capacitive loads up to 1000 pF, as demonstrated in datasheet Figure 14 (step response with CLOAD = 1000 pF). For loads >1000 pF, a series resistor (≤10 Ω) between OUT and capacitor is recommended to prevent peaking.
