Product details
Overview
LTC6101HVCCS5#TRMPBF from Analog Devices is a high-voltage, high-side current sense amplifier in 5-lead TSOT-23 package, delivering 1μs step response, ±300μV max input offset voltage, and operation from 5V to 100V 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#TRMPBF datasheet, LTC6101HVCCS5#TRMPBF pinout, LTC6101HVCCS5#TRMPBF application, or LTC6101HVCCS5#TRMPBF equivalent, key selection criteria include high common-mode voltage tolerance (100V), low quiescent current (230μA at 12V), gain configurability via external resistors, and specified 0°C to 70°C operating range.
Technical Context
The LTC6101HVCCS5#TRMPBF uses a current-output architecture where output current IOUT = VSENSE/RIN, enabling precise level-shifting of high-side shunt signals to ground-referenced voltage via ROUT. Its internal sense amplifier forces –IN to match +IN potential, eliminating common-mode rejection dependency on resistor matching.
It supports unidirectional sensing with 500mV full-scale input sense voltage, 118dB min PSRR, and operates across –40°C to 125°C junction temperature. The TSOT-23 package provides high-voltage spacing compliant with 105V absolute maximum rating between V+ and V–.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5V to 100V - enables direct monitoring of 48V, 60V, and 96V industrial and automotive bus rails without level-shifting circuitry. |
| Input Offset Voltage | ±300μV max - allows use of smaller shunt resistors (e.g., 5mΩ) while maintaining <1% error at 20mA load current. |
| Step Response Time | 1μs (to 2.5V on 5V output step) - supports fast overcurrent detection and real-time load transient tracking. |
| Supply Current | 230μA typical at 12V - minimizes parasitic loading in always-on battery monitoring systems. |
| Input Sense Voltage Full Scale | 500mV - sets maximum measurable shunt drop, defining dynamic range ceiling for resolution vs. power loss trade-off. |
| Power Supply Rejection Ratio | 118dB min - ensures stable output under noisy high-voltage rail conditions, critical in motor drive and SMPS feedback paths. |
| Operating Temperature Range | 0°C to 70°C (specified), –40°C to 125°C (operating) - validated for commercial and extended industrial ambient environments. |
Pinout & Package
Package: 5-Lead Plastic TSOT-23 (ThinSOT™), 1mm profile, high-voltage pin spacing per LTC6101HV family requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN | High-side sense input (non-inverting) | Connected directly to load side of shunt resistor; establishes reference point for differential sense voltage measurement. |
| –IN | High-side sense input (inverting) | Driven to same potential as +IN by internal amplifier; forms Kelvin connection node with external RIN to V+. |
| V+ | Positive supply input | Supplies operating current; also serves as common-mode reference for shunt placement - connect to high-side of sense resistor to exclude IC supply current from measurement. |
| V– | Negative supply / ground reference | Return path for supply current and output load; tied to system ground to enable ground-referenced output voltage generation. |
| OUT | Current output terminal | Sources IOUT = VSENSE/RIN; requires external ROUT to ground to generate analog output voltage VOUT = IOUT × ROUT. |
Key Features
| Feature | Design Value |
|---|---|
| High common-mode voltage operation | Supports direct sensing up to 100V rail - eliminates need for isolated amplifiers or resistive dividers in telecom and EV auxiliary systems. |
| Configurable gain via external resistors | RIN and ROUT set transconductance and output scaling independently - enables optimization for resolution (low RIN) or output drive (high ROUT) without changing IC. |
| Low input bias current | 170nA max - reduces error contribution from PCB trace resistance and enables accurate Kelvin sensing even with long interconnects. |
| Fast transient response | 1μs rise time - meets cycle-by-cycle overcurrent protection timing requirements in DC-DC controllers and motor gate drivers. |
| High PSRR | 118dB minimum - maintains accuracy during switching noise events on shared power rails, such as in multi-rail industrial PLCs. |
Applications
| Battery Management System (BMS) | Industrial Power Supply Monitoring |

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 |
|---|---|---|---|
| INA240A1QDRQ1 | Fixed gain (20V/V), 80V max supply, 50μV max offset, SOIC-8 package | Lower offset enables higher precision at low currents but lacks gain flexibility and HV headroom | Select when fixed-gain simplicity and ultra-low offset outweigh need for 100V operation or resistor-programmable scaling |
| MAX40056ATA+T | Current-output architecture like LTC6101HV, 65V max supply, ±150μV max offset, 8-pin TDFN | Smaller offset and faster 350ns response, but limited to 65V - unsuitable for 96V industrial rails | Select when sub-65V systems demand fastest response and lowest offset, and TDFN thermal performance is prioritized |
Compared with INA240A1QDRQ1 and MAX40056ATA+T, the LTC6101HVCCS5#TRMPBF uniquely balances 100V operation, resistor-configurable gain, and 1μs response - making it optimal for cost-sensitive, space-constrained designs requiring wide input voltage adaptability without sacrificing speed or accuracy.

FAQ
What is the absolute maximum supply voltage rating for the LTC6101HVCCS5#TRMPBF?
The LTC6101HVCCS5#TRMPBF has an absolute maximum total supply voltage (V+ to V–) of 105V, with recommended operating range from 5V to 100V. Exceeding 105V risks permanent damage, and operation above 100V voids parametric guarantees per the datasheet Absolute Maximum Ratings table.
How does the LTC6101HVCCS5#TRMPBF generate its output signal?
The LTC6101HVCCS5#TRMPBF outputs a current IOUT = VSENSE/RIN, where VSENSE is the voltage across the external shunt resistor. An external ROUT from OUT to V– converts this to voltage: VOUT = IOUT × ROUT. This current-output architecture decouples gain setting from output loading effects.
What is the specified temperature range for the LTC6101HVCCS5#TRMPBF?
The LTC6101HVCCS5#TRMPBF is specified over 0°C to 70°C ambient temperature, with full operational capability from –40°C to 125°C junction temperature. Electrical characteristics including offset, PSRR, and response time are guaranteed only within the 0°C to 70°C range per the ordering information table.
Can the LTC6101HVCCS5#TRMPBF be used in bidirectional current sensing applications?
No - the LTC6101HVCCS5#TRMPBF is a unidirectional high-side current sense amplifier. Its architecture sources output current proportional to positive VSENSE only; it cannot resolve reverse current flow. For bidirectional sensing, consider the LTC6102 or discrete op-amp solutions with level-shifting.
What package type and marking code does the LTC6101HVCCS5#TRMPBF use?
The LTC6101HVCCS5#TRMPBF uses a 5-lead plastic TSOT-23 (ThinSOT™) package with lead-free finish and tape-and-reel packaging (500 pieces per reel). Its top-side marking code is LTBSZ, as confirmed in the Analog Devices order information table for HV-grade S5 variants.
