Product details
Overview
LTC6101HVBHS5#TRMPBF from Analog Devices is a high-voltage, high-side current sense amplifier in 5-lead TSOT-23 package, delivering 1μs step response, ±450µV 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 LTC6101HVBHS5#TRMPBF datasheet, LTC6101HVBHS5#TRMPBF pinout, LTC6101HVBHS5#TRMPBF application, or LTC6101HVBHS5#TRMPBF equivalent, key selection criteria include high common-mode voltage tolerance (up to 100V), low quiescent current (350µA at 100V), –40°C to 125°C operating range, and configurable gain via external RIN/ROUT.
Technical Context
The LTC6101HVBHS5#TRMPBF uses a feedback-controlled transconductance architecture: its internal amplifier forces –IN to match +IN potential, enabling precise VSENSE measurement across an external shunt. Output current IOUT = VSENSE/RIN is sourced from the OUT pin, with gain set by RIN and ROUT (VOUT = IOUT × ROUT).
It supports single-supply operation with V– tied to ground, features 118dB min PSRR, and maintains accuracy under high dV/dt conditions due to internal high-voltage isolation design-critical for 48V/60V bus monitoring where common-mode transients exceed 100V/ns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5V to 100V - enables direct sensing on 48V, 60V, and 96V industrial/automotive buses without level-shifting. |
| Input Offset Voltage | ±450µV max - ensures ≤9mV error at 500mV full-scale sense voltage, supporting ≥46dB dynamic range with 50mΩ shunt. |
| Step Response Time | 1µs to 2.5V on 5V output step - allows real-time overcurrent detection for fast-acting protection circuits. |
| Supply Current | 350µA typical at 100V - minimizes self-heating and power loss in always-on battery monitoring systems. |
| Input Sense Voltage | 500mV max full-scale - permits use of low-value shunts (e.g., 10mΩ at 50A) to limit I²R losses below 25W. |
| PSRR | 118dB min - rejects supply ripple and noise, preserving accuracy when powered from noisy DC-DC converters. |
| Operating Temp | –40°C to 125°C - qualified for under-hood automotive and industrial motor drive environments. |
Pinout & Package
Package: 5-lead TSOT-23 (ThinSOT™), 1mm profile, HV-optimized spacing per Absolute Maximum Ratings (105V V+ to V–).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN | High-side sense input | Connected to load side of shunt; sets reference point for VSENSE measurement under high common-mode voltage. |
| –IN | Feedback input | Internally driven to match +IN; external RIN from V+ defines transconductance gain (IOUT = VSENSE/RIN). |
| V+ | Positive supply | Accepts 5V–100V; supply current drawn here; connection polarity determines whether LTC6101 current is included in measurement. |
| V– | Negative supply / ground | Tied to system ground; provides return path for output current and establishes ground-referenced VOUT. |
| OUT | Current output | Sources proportional current (IOUT) to external ROUT; VOUT = IOUT × ROUT enables flexible analog interfacing. |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage common-mode range | Supports 5V–100V supply with 105V absolute max - eliminates need for isolated amplifiers in 48V/60V systems. |
| Configurable gain architecture | External RIN/ROUT set gain from 20× to 100× - enables optimization for resolution vs. dynamic range without changing IC. |
| Low input bias current | 170nA max - reduces error from PCB trace resistance and enables accurate Kelvin sensing with <10mΩ interconnects. |
| Fast transient response | 1µs rise time - meets ISO 16750-2 pulse 4a/b requirements for automotive load dump detection. |
| High PSRR | 118dB - maintains 0.001% gain stability when powered from switching regulators with >100mVpp ripple. |

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 |
|---|---|---|---|

FAQ
What is the maximum common-mode voltage the LTC6101HVBHS5#TRMPBF can handle?
The LTC6101HVBHS5#TRMPBF supports a total supply voltage (V+ to V–) up to 105V absolute maximum, with specified operation from 5V to 100V. This enables direct high-side sensing on 48V, 60V, and 96V buses without external level-shifting circuitry. The device's internal architecture isolates the input stage to tolerate high dV/dt transients typical in motor drive and automotive load-dump scenarios.
How does the LTC6101HVBHS5#TRMPBF achieve ground-referenced output with high common-mode input?
The LTC6101HVBHS5#TRMPBF achieves ground-referenced output through its transconductance architecture: it forces –IN to track +IN, then sources output current IOUT = VSENSE/RIN from the OUT pin. When ROUT is tied between OUT and V– (ground), VOUT = IOUT × ROUT becomes ground-referenced-enabling direct interface with ADCs, comparators, or microcontrollers without isolation.
Can the LTC6101HVBHS5#TRMPBF be used with bidirectional current sensing?
No, the LTC6101HVBHS5#TRMPBF is a unidirectional high-side current sense amplifier optimized for positive current flow from V+ through the shunt to load. Its output current is sourced only and cannot sink; it does not support reverse current detection. For bidirectional applications, consider alternatives like the INA240 series, which provide true differential output capable of indicating direction.
What is the minimum shunt resistor value recommended for use with the LTC6101HVBHS5#TRMPBF?
The minimum shunt resistor value depends on required resolution and maximum load current. With ±450µV max offset and 500mV full-scale input, a 10mΩ shunt yields 45mV offset error at 4.5A-acceptable for many 10A-range applications. For sub-amp resolution, a 50mΩ shunt gives 9mV offset error at 1A. Always verify Kelvin layout and trace resistance to keep errors <0.5%.
Does the LTC6101HVBHS5#TRMPBF require external compensation components?
No, the LTC6101HVBHS5#TRMPBF is internally compensated and requires no external capacitors for stability. Its architecture is optimized for direct connection to RIN and ROUT resistors. However, a 100pF–1nF capacitor across ROUT may be added to reduce high-frequency noise if interfacing with sensitive ADCs-this does not affect loop stability.
