Product details
Overview
LTC6101HVCCS5#TRPBF from Analog Devices is a high-voltage, high-side current sense amplifier in 5-lead TSOT-23 package, delivering 1 µs step response, ±300 µV max input offset voltage, and operation from 5 V to 100 V supply. It converts shunt voltage into ground-referenced output current for precision monitoring in automotive battery management and industrial power supplies.
For engineers reviewing the LTC6101HVCCS5#TRPBF datasheet, LTC6101HVCCS5#TRPBF pinout, LTC6101HVCCS5#TRPBF application, or LTC6101HVCCS5#TRPBF equivalent, this page provides verified specifications, validated pin functions, real-world use cases, and confirmed alternative options for high-voltage unidirectional current sensing.
Technical Context
The LTC6101HVCCS5#TRPBF uses a high-impedance feedback loop to force –IN to match +IN potential, enabling precise current-to-current conversion via external RIN. Its internal MOSFET sources output current proportional to VSENSE/RIN, independent of common-mode voltage up to 100 V.
It supports gain configuration through RIN and ROUT, delivers 140 kHz signal bandwidth at 200 µA load, and maintains 118 dB PSRR across 5 V–100 V supply range - critical for noise-immune operation in switching power rails and motor drives.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5 V to 100 V - enables direct monitoring of 48 V, 60 V, and 96 V battery systems without level-shifting circuitry. |
| Input Offset Voltage | ±300 µV max - allows accurate sensing down to ~6 mA with 50 mΩ shunt (at gain = 100), minimizing minimum detectable current. |
| Step Response Time | 1 µs to 2.5 V on 5 V output step - supports fast overcurrent detection for protection in DC-DC converters and e-fuse applications. |
| PSRR | 118 dB min - rejects supply ripple and switching noise in high-noise environments like motor controllers and telecom rectifiers. |
| Input Bias Current | 170 nA max - ensures negligible error from trace resistance when using Kelvin-connected shunts in high-precision PCB layouts. |
| Max Output Current | 1 mA - sets upper limit for ROUT selection; e.g., 5 kΩ yields 5 V full-scale output while staying within safe operating area. |
| Operating Temp Range | 0°C to 70°C (C-grade) - qualified for commercial/industrial ambient conditions without derating in enclosed power modules. |
Pinout & Package
Package: 5-lead plastic TSOT-23 (thin profile, 1 mm height), optimized for high-voltage spacing per LTC6101HV series requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN | High-side sense input (non-inverting) | Connected directly to load side of shunt resistor; defines reference point for VSENSE measurement. |
| –IN | Feedback input (inverting) | Driven to same potential as +IN by internal amplifier; RIN from V+ to –IN sets transconductance IOUT = VSENSE/RIN. |
| V+ | Positive supply input | Supplies operating current; connection point determines whether LTC6101HVCCS5#TRPBF current is included in sensed load current. |
| V– | Negative supply / ground reference | Serves as output return and ground reference for output voltage; must be low-impedance for stable current sourcing. |
| OUT | Current output terminal | Sources proportional current (IOUT) to ROUT; output voltage VOUT = IOUT × ROUT referenced to V–. |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage operation | Rated for 100 V supply with 105 V absolute maximum - eliminates need for external high-side biasing or isolation in 48 V–96 V systems. |
| Configurable gain architecture | Gain set by ratio ROUT/RIN - enables flexible full-scale output scaling (e.g., 250 mV/A or 2.5 V/A) without changing IC. |
| Low quiescent current | 230 µA typical at 12 V supply - reduces self-heating and power overhead in always-on battery monitoring circuits. |
| Kelvin-input compatible | Separate +IN/–IN pins support 4-wire shunt connections - suppresses errors from PCB trace resistance up to 10 A load currents. |
| Fast overload recovery | Indefinite output short-circuit duration to V– - survives accidental grounding of OUT during fault events without latch-up or damage. |
Applications
| Battery Management System (BMS) | Industrial DC Power Supply Monitoring |

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 (50 V/V), 2.7 V–65 V supply, 1.5 µs response, ±150 µV offset | Requires external op-amp for gain adjustment; lower max voltage limits use in >65 V systems | Preferred where fixed-gain simplicity and lower offset outweigh need for 100 V operation |
| INA286AIDR | 2.7 V–18 V supply only, 350 µV offset, 130 kHz bandwidth, SOIC-8 package | Not rated for >18 V common-mode; unsuitable for 48 V+ battery or telecom applications | Valid only for low-voltage industrial PLC I/O modules; not a functional substitute for LTC6101HVCCS5#TRPBF |
Compared with MAX40056ASA+T and INA286AIDR, the LTC6101HVCCS5#TRPBF uniquely supports 100 V operation with user-configurable gain and 1 µs response - making it the sole option among the three for 48 V–96 V high-speed protection in space-constrained designs.

FAQ
What is the maximum common-mode voltage supported by the LTC6101HVCCS5#TRPBF?
The LTC6101HVCCS5#TRPBF supports a total supply voltage range of 5 V to 100 V, with an absolute maximum rating of 105 V. Its high-side sensing architecture allows it to accurately measure current with common-mode voltages up to 100 V referenced to V–, making it suitable for 48 V and 96 V battery systems without external level-shifting components.
How does the LTC6101HVCCS5#TRPBF achieve gain configuration?
The LTC6101HVCCS5#TRPBF uses external resistors to set gain: RIN between V+ and –IN determines transconductance (IOUT = VSENSE/RIN), and ROUT between OUT and V– converts output current to voltage (VOUT = IOUT × ROUT). The effective gain is VOUT/VSENSE = ROUT/RIN, enabling flexible full-scale scaling without changing the IC.
Can the LTC6101HVCCS5#TRPBF be used in bidirectional current sensing applications?
No - the LTC6101HVCCS5#TRPBF is a unidirectional high-side current sense amplifier optimized for positive current flow from V+ through the shunt to load. It lacks the internal architecture for negative current detection or bipolar output swing. For bidirectional sensing, consider the LTC6102 or discrete solutions with dual amplifiers.
What is the significance of the "C" grade in LTC6101HVCCS5#TRPBF?
The "C" in LTC6101HVCCS5#TRPBF denotes the commercial temperature grade, specifying guaranteed operation from 0°C to 70°C. This grade is qualified for ambient conditions in enclosed power modules, telecom equipment, and industrial control panels where extended temperature coverage is not required - offering cost and availability advantages over I- or H-grade variants.
Does the LTC6101HVCCS5#TRPBF require a minimum load on the OUT pin?
No - the LTC6101HVCCS5#TRPBF outputs a current source, not a voltage source. It can drive open-circuit loads (high-impedance inputs) or terminate into ROUT to generate VOUT. However, for stable operation and specified bandwidth, a capacitive load ≤100 pF is recommended; larger capacitors may require series resistance to prevent peaking or oscillation.
