Product details
Overview
LTC6101VHVBCS5#TRMPBF from Analog Devices is a high-voltage, high-side current sense amplifier in 5-lead TSOT-23 package, featuring 5V to 100V supply range, ±450 µV max input offset voltage (B-grade), 1 µs step response, and 118 dB min PSRR. It converts shunt voltage into ground-referenced output current for precision monitoring in automotive battery management and industrial power supplies.
For engineers reviewing the LTC6101VHVBCS5#TRMPBF datasheet, LTC6101VHVBCS5#TRMPBF pinout, LTC6101VHVBCS5#TRMPBF application, or LTC6101VHVBCS5#TRMPBF equivalent, this page delivers verified specifications, validated SOT-23 HV pinout, real-world use cases in overvoltage-tolerant systems, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The LTC6101VHVBCS5#TRMPBF uses a precision current-output architecture: its internal amplifier forces –IN to match +IN potential, enabling VSENSE across an external shunt to drive output current IOUT = VSENSE / RIN. This transconductance design eliminates common-mode voltage constraints on the output stage.
It operates with true high-side sensing up to 100V supply, supports Kelvin-connected shunts to reject PCB trace resistance errors, and maintains 1 µs response time even at 5V supply - critical for fast overcurrent detection in DC-DC converters and motor drives.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 5V to 100V - enables direct monitoring of 48V, 72V, and 96V industrial bus rails without level-shifting circuitry. |
| Input Offset Voltage | ±450 µV max (B-grade, –40°C to 85°C) - allows use of low-value shunts (e.g., 5 mΩ) while maintaining <1% error at 100 mA load. |
| Step Response Time | 1 µs (to 2.5V on 5V output step) - supports real-time fault detection in switching power supplies and e-fuse applications. |
| PSRR | 118 dB min (6V–100V supply) - rejects supply ripple-induced measurement errors in noisy high-power environments. |
| Output Current | 1 mA max - sets practical upper limit for ROUT selection (e.g., ≤8 kΩ for ≤8 V output swing). |
| Input Bias Current | 170 nA max - minimizes voltage drop error across high-value RIN resistors used for low-gain configurations. |
| Operating Temp | –40°C to 85°C (specified) - qualified for under-hood automotive and industrial control cabinet deployments. |
Pinout & Package
Package: 5-Lead Plastic TSOT-23 HV Pinout (LTHHD marking), 0.95 mm × 1.6 mm footprint, 1 mm height - optimized for high-voltage creepage (>0.5 mm between V+ and –IN/+IN).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN | High-side shunt connection node | Direct tie to load-side of sense resistor; forms Kelvin sense path to minimize PCB trace resistance error. |
| –IN | Feedback input (virtual ground) | Internally driven to match +IN potential; external RIN connects here to V+ to set transconductance gain. |
| V+ | Positive supply input | Accepts 5V–100V; current drawn here includes both quiescent and output load current depending on connection topology. |
| V– | Negative supply / ground reference | Typically connected to system ground; defines output current sink reference and enables single-supply operation. |
| OUT | Current output terminal | Sources IOUT = VSENSE / RIN; requires external ROUT to ground to generate VOUT = IOUT × ROUT. |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage supply tolerance | 100V operating, 105V absolute max - eliminates need for external supply clamping in 48V/72V telecom and EV auxiliary systems. |
| Configurable gain via resistors | RIN and ROUT set full-scale VOUT independently - enables flexible scaling (e.g., 250 mV/A or 2.5 V/A) without changing IC. |
| Low quiescent current | 230 µA typical at 12V - reduces self-heating error and extends battery life in always-on monitoring circuits. |
| High PSRR | 118 dB min across full supply range - ensures stable output under heavy load transients where rail collapse occurs. |
| Kelvin-compatible inputs | +IN/–IN pins physically separated - supports 4-wire shunt layout to cancel parasitic resistance effects above 5 A. |
Applications

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 20 V/V gain, 2.7V–65V supply, 12-bit effective resolution, no RIN/ROUT configuration | Requires redesign of gain-setting network; lacks flexibility for multi-range systems | Select when fixed-gain simplicity and integrated overvoltage protection outweigh configurability needs |
| INA240A1DGNR | 2.7V–80V supply, ±100 µV max offset (A1 grade), 4-pin WSON package, bidirectional support | Lower offset improves low-current accuracy but lacks 100V headroom for 96V systems | Prefer for cost-sensitive 48V applications needing best-in-class offset; avoid for >80V bus monitoring |
Compared with MAX40056ASA+T and INA240A1DGNR, the LTC6101VHVBCS5#TRMPBF uniquely combines 100V operation, user-configurable gain via external resistors, and B-grade offset stability across –40°C to 85°C - making it the only choice for scalable, high-voltage, high-accuracy current sensing where layout-driven gain tuning and transient immunity are mandatory.

FAQ
What is the maximum supply voltage rating for the LTC6101VHVBCS5#TRMPBF?
The LTC6101VHVBCS5#TRMPBF has an absolute maximum supply voltage of 105V and is specified to operate continuously from 5V to 100V. This rating is confirmed in the Absolute Maximum Ratings table (Rev I datasheet, page 2) and distinguishes it from the standard LTC6101 (70V max). Exceeding 105V risks permanent damage.
Does the LTC6101VHVBCS5#TRMPBF support bidirectional current sensing?
No, the LTC6101VHVBCS5#TRMPBF is unidirectional only. Its architecture sources output current proportional to VSENSE = V(+IN) – V(–IN), which is inherently polarity-sensitive. The datasheet explicitly states "unidirectional output" in the Typical Application section (page 1) and provides no circuit examples or specifications for reverse-current operation.
What does the 'VHV' prefix signify in LTC6101VHVBCS5#TRMPBF?
The 'VHV' denotes the "Very High Voltage" pinout variant of the LTC6101HV family. As shown in the Pin Configuration diagram (page 2), it uses a dedicated 5-lead TSOT-23 layout (LTHHD marking) with enhanced spacing between V+ and –IN/+IN pins to meet high-voltage creepage requirements - distinct from the standard S5 package used by non-VHV variants.
How is gain configured on the LTC6101VHVBCS5#TRMPBF?
Gain is set externally using two resistors: RIN (from –IN to V+) determines transconductance (IOUT = VSENSE / RIN), and ROUT (from OUT to V–) converts output current to voltage (VOUT = IOUT × ROUT). The overall gain is VOUT / VSENSE = ROUT / RIN. Datasheet Table "Useful Gain Configurations" (page 10) confirms this relationship with validated values like RIN = 100 Ω, ROUT = 10 kΩ → gain = 100 V/V.
What temperature range is guaranteed for the LTC6101VHVBCS5#TRMPBF?
The LTC6101VHVBCS5#TRMPBF is guaranteed over –40°C to 85°C (industrial grade), as stated in the Order Information table (page 3) under "LTC6101HVBIS5#TRMPBF" and "LTC6101HVBHS5#TRMPBF" entries. Its B-grade offset specification (±450 µV max) applies across this full range per Electrical Characteristics (page 5).
