Product details
Overview
LTC6101VHVCCS5#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 step response, and ±170nA max input bias current. It converts shunt voltage into ground-referenced output current for precision monitoring in automotive battery management and industrial power supplies.
For engineers reviewing the LTC6101VHVCCS5#TRPBF datasheet, LTC6101VHVCCS5#TRPBF pinout, LTC6101VHVCCS5#TRPBF application, or LTC6101VHVCCS5#TRPBF equivalent, key selection criteria include high common-mode voltage tolerance (up to 105V abs max), configurable gain via external RIN/ROUT, low quiescent current (230µA at 12V), and –40°C to 85°C specified temperature range.
Technical Context
The LTC6101VHVCCS5#TRPBF uses a high-impedance feedback loop to force –IN to match +IN potential, enabling accurate VSENSE measurement across an external shunt. Its transconductance architecture delivers output current IOUT = VSENSE/RIN, independent of supply voltage within 5V–100V range.
It supports unidirectional sensing with 500mV full-scale input, 118dB min PSRR, and operates with no internal reference-gain and output scaling are fully resistor-defined. The HV pinout variant ensures adequate creepage/clearance for >100V systems, validated per SOT-23 HV layout guidelines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5V to 100V - enables direct monitoring of 48V, 72V, and 96V industrial/automotive bus rails without level-shifting. |
| Input Offset Voltage | ±300µV max - allows use of small-value shunts (e.g., 5mΩ) while maintaining <1% error at 1A load. |
| Step Response Time | 1µs (to 2.5V on 5V output step) - supports fast overcurrent detection and protection in switching power supplies. |
| Input Bias Current | 170nA max - minimizes error contribution from PCB trace resistance and enables Kelvin-sense accuracy. |
| Power Supply Rejection | 118dB min - rejects ripple and noise on high-voltage rails, preserving measurement integrity in noisy environments. |
| Output Current Drive | 1mA max - sets practical upper limit for ROUT when interfacing with ADCs or op-amp buffers. |
| Specified Temp Range | –40°C to 85°C - qualified for under-hood automotive and industrial control cabinet applications. |
Pinout & Package
Package: 5-Lead Plastic TSOT-23 HV Pinout (LTHHD marking), 1mm profile, optimized for high-voltage spacing between pins 1 (–IN) and 5 (OUT).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN | High-side sense input (load-side of shunt) | Must connect directly or via Kelvin trace to shunt's load terminal; defines common-mode reference point. |
| –IN | Feedback input (system-rail side of shunt) | Driven to same potential as +IN; connects to shunt's rail-side terminal and RIN to V+. |
| V+ | Positive supply input | Supplies operating current; also serves as high-side reference for RIN connection and determines VSENSE common-mode range. |
| OUT | Current-output terminal | Sources IOUT = VSENSE/RIN; requires external ROUT to ground/V– to generate voltage output. |
| V– | Negative supply / ground reference | Return path for supply current and ROUT; may be tied to system ground in single-supply configurations. |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage operation | 105V absolute maximum supply rating - eliminates need for external voltage dividers or isolated supplies in 48–96V systems. |
| Resistor-configurable gain | Gain = ROUT/RIN - enables precise scaling (e.g., 250mV/A or 2.5V/A) without trimming or calibration. |
| Low quiescent current | 230µA at 12V - reduces self-heating and enables always-on monitoring in battery-backed systems. |
| Kelvin-sense compatible inputs | Separate +IN/–IN pins with high CMRR - suppresses errors from PCB trace resistance up to 10mΩ at 10A. |
| Wide dynamic range | 500mV full-scale input with 300µV offset - supports 16-bit resolution over >60dB current range (e.g., 10mA–10A). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage high-side current sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX40056ASA+T | Fixed-gain (50V/V), 2.7V–65V supply, 1.5µs response, 600µV offset | Requires external op-amp for gain adjustment; lower voltage rating limits use in >65V systems | Preferred where fixed gain simplifies design and supply stays ≤65V; not suitable for 100V bus monitoring. |
| INA240A1QDRQ1 | Bi-directional, 2.7V–80V supply, 120µV offset, 1.5µs response, integrated ESD protection | Supports reverse-current detection; higher ESD robustness but lacks HV pinout spacing for >80V creepage | Best for automotive 12V/48V systems requiring bi-directional sensing; insufficient clearance for 100V industrial use. |
Compared with MAX40056ASA+T and INA240A1QDRQ1, the LTC6101VHVCCS5#TRPBF offers superior high-voltage margin (105V abs max), resistor-defined gain flexibility, and HV-optimized pinout-critical for reliable operation in 72V–96V industrial and energy storage systems where layout creepage and thermal drift dominate error budgets.

FAQ
What is the absolute maximum supply voltage rating for the LTC6101VHVCCS5#TRPBF?
The LTC6101VHVCCS5#TRPBF has an absolute maximum total supply voltage (V+ to V–) of 105V, as specified in the Absolute Maximum Ratings table. This exceeds the 100V operating range and provides safety margin for transient spikes in high-voltage industrial and automotive applications. Operation beyond 105V risks permanent device damage.
Can the LTC6101VHVCCS5#TRPBF be used with a 3.3V microcontroller ADC input?
Yes - the LTC6101VHVCCS5#TRPBF outputs current, so an external ROUT resistor converts IOUT to voltage. Selecting ROUT = 3.3kΩ yields 0–3.3V output for 0–1mA IOUT, matching standard 3.3V ADC full-scale range. Ensure ROUT is placed between OUT and V– (ground), and verify load current does not exceed 1mA.
How does the LTC6101VHVCCS5#TRPBF achieve high accuracy despite high common-mode voltage?
The LTC6101VHVCCS5#TRPBF achieves high accuracy through a precision feedback loop that forces –IN to track +IN, rejecting common-mode voltage via high open-loop gain. Its 118dB PSRR and ±300µV input offset are characterized up to 100V supply, and the HV pinout minimizes leakage paths that could degrade CMRR at elevated voltages.
Is the LTC6101VHVCCS5#TRPBF pin-compatible with other variants in the LTC6101 family?
No - the LTC6101VHVCCS5#TRPBF uses the HV pinout configuration (pin 1 = +IN, pin 2 = –IN, pin 3 = V+, pin 4 = V–, pin 5 = OUT), which differs from the standard S5 pinout (pin 1 = –IN, pin 2 = NC, pin 3 = +IN, pin 4 = V+, pin 5 = OUT). PCB layout must match LTHHD-marked HV pinout; mixing pinouts causes functional failure.
What is the minimum recommended sense resistor value for the LTC6101VHVCCS5#TRPBF?
The minimum recommended sense resistor depends on required resolution and max load current. With ±300µV offset and 500mV full-scale input, a 1mΩ shunt yields 300µV at 300A - impractical due to power loss. For 10A max and <1% offset error, RSENSE ≥ 30mΩ is advised. Always use Kelvin connections to avoid trace-resistance errors.
