Product details
Overview
LTC6101HVAHMS8#TRPBF from Analog Devices is a high-voltage, high-side current sense amplifier in 8-lead MSOP package, operating from 5V to 100V supply with ±300µV max input offset voltage, 1µs response time, and −40°C to 125°C specified temperature range. It converts shunt voltage into ground-referenced output current for precision monitoring in battery management, industrial power supplies, and overcurrent protection circuits.
For engineers reviewing the LTC6101HVAHMS8#TRPBF datasheet, LTC6101HVAHMS8#TRPBF pinout, LTC6101HVAHMS8#TRPBF application, or LTC6101HVAHMS8#TRPBF equivalent, key selection criteria include high common-mode voltage support (up to 100V), low quiescent current (230µA at 12V), configurable gain via external resistors, PSRR ≥118dB, and MSOP-8 thermal performance (θJA = 300°C/W).
Technical Context
The LTC6101HVAHMS8#TRPBF uses a high-impedance feedback loop to force the –IN pin to match +IN potential, enabling precise current sensing across a user-selected shunt resistor. Its transconductance architecture delivers output current IOUT = VSENSE/RIN, independent of supply voltage variations.
It features internal MOSFET-based current sourcing to the OUT pin, supporting programmable gain via RIN and ROUT, with guaranteed operation up to 100V supply and absolute maximum rating of 105V. Input bias current is limited to 170nA max, minimizing error in high-RIN configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5V to 100V - supports direct connection to high-voltage rails like 48V telecom, 72V EV subsystems, or 96V industrial DC buses without level-shifting. |
| Input Offset Voltage | ±300µV max - enables accurate sensing with small shunt resistors (e.g., 5mΩ at 20A yields 100mV signal, limiting offset-induced error to ±6mA equivalent load current). |
| Response Time | 1µs (to 2.5V on 5V step) - suitable for fast overcurrent detection and real-time load warning in power converters and motor drives. |
| Power Supply Rejection | ≥118dB - maintains output accuracy despite ripple or noise on high-voltage supply lines, critical in noisy industrial environments. |
| Supply Current | 230µA typical at 12V - reduces self-heating and system power overhead in always-on monitoring applications like battery fuel gauging. |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive, industrial control cabinets, and outdoor power equipment deployments. |
| Input Sense Range | 0–500mV full scale - accommodates wide dynamic current ranges (e.g., 10mA–200A) using appropriate shunt values without clipping. |
Pinout & Package
Package: 8-Lead Plastic MSOP (3mm × 3mm, 1.1mm height), with high-voltage spacing optimized for >100V operation. Pin 1 marked by dot; exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (–IN) | Inverting input of internal sense amplifier | Driven to same potential as +IN; connects to high-side of shunt via Kelvin trace to reject PCB trace resistance errors. |
| 2 (V–) | Negative supply / ground reference | Serves as output return path and ground reference for VOUT; must be low-impedance to avoid gain error from IR drop. |
| 3 (NC) | No connect | Internally unused; must remain unconnected per datasheet to prevent latch-up or parametric shift. |
| 4 (OUT) | Current output terminal | Sources IOUT = VSENSE/RIN; requires external ROUT to ground to generate VOUT = IOUT × ROUT. |
| 5 (+IN) | Non-inverting input | Connects directly to load side of shunt; establishes common-mode reference point for high-side sensing. |
| 6 (V+) | Positive supply input | Draws supply current; connects to high-voltage rail; placement determines whether LTC6101HVAHMS8#TRPBF current is included in measurement. |
| 7 (NC) | No connect | Internally unused; must remain unconnected. |
| 8 (NC) | No connect | Internally unused; must remain unconnected. |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage operation | 100V supply range with 105V absolute maximum - eliminates need for external level-shifting or isolation in 48V–96V systems. |
| Low-offset transconductance | ±300µV max offset with 170nA max input bias - enables use of low-value, low-power shunts while preserving >60dB dynamic range. |
| Configurable gain architecture | Gain set by external RIN/ROUT ratio - allows flexible scaling (e.g., 20× to 100×) without changing IC, simplifying BOM and layout reuse. |
| Fast transient response | 1µs step response - supports cycle-by-cycle overcurrent protection in switching regulators and motor controllers. |
| High PSRR | ≥118dB rejection of supply noise - ensures stable output under heavy load transients where V+ rail exhibits ripple or droop. |
| Wide temperature qualification | –40°C to 125°C operation - meets AEC-Q100 Grade 0 stress requirements for automotive under-hood and industrial edge computing. |

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 | 5.5V to 65V supply range; 12-bit integrated ADC; fixed 20× gain; SO-8 package | Requires external ADC interface; lower voltage ceiling limits use in >65V systems like EV traction inverters | Select when digital output and integrated conversion are preferred over analog flexibility and higher voltage capability. |
| INA240A1QDRQ1 | 2.7V to 80V supply; ±5µV offset (typ); 400kHz bandwidth; SO-8 package; AEC-Q100 qualified | Lower offset improves resolution at ultra-low currents but lacks 100V headroom and 1µs speed of LTC6101HVAHMS8#TRPBF | Select for automotive body electronics requiring lowest offset in 12V/24V systems, not for 48V+ or fast-trip applications. |
Compared with MAX40056ASA+T and INA240A1QDRQ1, the LTC6101HVAHMS8#TRPBF offers superior high-voltage margin (100V vs. 65V/80V), faster response (1µs vs. ~3µs), and analog gain configurability-making it uniquely suited for 48V–96V industrial and telecom power monitoring where flexibility and speed are critical.

FAQ
What is the maximum supply voltage the LTC6101HVAHMS8#TRPBF can withstand?
The LTC6101HVAHMS8#TRPBF has an absolute maximum supply voltage rating of 105V between V+ and V– pins. It operates continuously over 5V to 100V, making it suitable for 48V, 72V, and 96V industrial and telecom power rails. Exceeding 105V risks permanent damage per Absolute Maximum Ratings table in the datasheet.
How does the LTC6101HVAHMS8#TRPBF achieve high-side current sensing without a level shifter?
The LTC6101HVAHMS8#TRPBF uses a proprietary high-impedance feedback architecture that forces the –IN pin to track the +IN pin potential, allowing it to measure voltage across a shunt placed between V+ and load while referencing output to V– (ground). This eliminates need for external level-shifting components, unlike op-amp-based solutions.
Can the LTC6101HVAHMS8#TRPBF be used with a single 5V supply?
No-the LTC6101HVAHMS8#TRPBF requires minimum 5V supply but is designed for high-side sensing where V+ connects to the high-voltage rail (e.g., 48V). Using only 5V defeats its high-voltage advantage. For true 5V-system applications, the standard LTC6101 (not HV version) is more appropriate and cost-optimized.
What is the purpose of the NC pins on the LTC6101HVAHMS8#TRPBF MSOP package?
Pins 3, 7, and 8 on the LTC6101HVAHMS8#TRPBF are no-connect (NC) terminals-internally unconnected and electrically isolated. They must remain unconnected on PCB layout to prevent parasitic coupling, leakage paths, or potential latch-up. Leaving them floating is safe; soldering or routing to ground or supply violates datasheet guidance.
Does the LTC6101HVAHMS8#TRPBF include built-in overtemperature protection?
No-the LTC6101HVAHMS8#TRPBF does not integrate thermal shutdown circuitry. Its absolute maximum junction temperature is 150°C, and it relies on proper PCB thermal design (copper pour, vias) and system-level thermal management. Designers must ensure θJA ≤ 300°C/W and ambient + self-heating stays within –40°C to 125°C operating range.
