Product details
Overview
LTC6101HVBCS5#TRPBF from Analog Devices is a high-voltage, high-side current sense amplifier in 5-lead TSOT-23 package, delivering 1 µs step response, ±450 µV max input offset voltage (B-grade), and operation from 5 V to 100 V supply. It converts shunt voltage to ground-referenced output current for precision monitoring in battery management, industrial power supplies, and overcurrent protection circuits.
For engineers reviewing the LTC6101HVBCS5#TRPBF datasheet, LTC6101HVBCS5#TRPBF pinout, LTC6101HVBCS5#TRPBF application, or LTC6101HVBCS5#TRPBF equivalent, key selection criteria include high common-mode voltage tolerance (105 V abs max), low quiescent current (350 µA at 100 V), gain configurability via external RIN/ROUT, and specified performance across –40°C to 85°C.
Technical Context
The LTC6101HVBCS5#TRPBF uses a high-impedance feedback loop to force –IN to match +IN potential, enabling precise current-to-current conversion via external RIN. Its transconductance architecture isolates the output from high common-mode voltages while maintaining DC accuracy.
It supports unidirectional sensing with 500 mV full-scale input range, 118 dB min PSRR, and 140 kHz signal bandwidth at 200 µA load. Output current (IOUT) scales linearly with VSENSE/RIN, and VOUT = IOUT × ROUT provides flexible voltage-level translation.
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 bus systems without level-shifting circuitry. |
| Input Offset Voltage (Max) | ±450 µV - limits minimum detectable current error to ~0.9 mA when using 500 mΩ shunt at 100× gain. |
| Step Response Time | 1 µs (to 2.5 V on 5 V output step) - supports fast overcurrent detection and real-time load transient tracking. |
| Power Supply Rejection Ratio | 118 dB min - suppresses supply ripple-induced errors in noisy industrial or automotive environments. |
| Supply Current (Typ) | 350 µA at 100 V - ensures minimal self-loading on high-voltage rails during continuous monitoring. |
| Input Sense Voltage Full Scale | 500 mV - allows use of low-value, low-power shunts (e.g., 1–10 mΩ) while preserving dynamic range. |
| Operating Temperature Range | –40°C to 85°C - qualified for industrial and automotive under-hood applications without derating. |
Pinout & Package
Package: 5-lead TSOT-23 (ThinSOT™), 1 mm profile, HV-optimized spacing per Absolute Maximum Rating of 105 V between V+ and V–.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: +IN | High-side sense input (non-inverting) | Connected directly to load-side terminal of shunt resistor; Kelvin connection required for <1% accuracy. |
| 2: –IN | High-side sense input (inverting) | Driven to same potential as +IN by internal amplifier; tied to system V+ via RIN to set transconductance. |
| 3: V+ | Positive supply input | Supplies operating current; connects to high-side rail; placement determines whether LTC6101HVBCS5#TRPBF current is included in measurement. |
| 4: V– | Negative supply / ground reference | Return path for supply current and output current; must be low-impedance ground for accurate VOUT generation. |
| 5: OUT | Current output terminal | Sources IOUT = VSENSE/RIN; requires external ROUT to ground to generate VOUT = IOUT × ROUT. |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage operation (5–100 V) | Eliminates need for isolated amplifiers or resistive dividers in 48 V–96 V systems, reducing BOM count and layout complexity. |
| Configurable gain via RIN/ROUT | Enables precise scaling (e.g., 20×, 50×, 100×) without changing IC; supports both current-output and voltage-output interfaces. |
| Low input bias current (170 nA max) | Minimizes error from trace resistance and shunt parasitics, critical for sub-10 mΩ shunt accuracy. |
| 1 µs fast response time | Supports cycle-by-cycle overcurrent shutdown in switch-mode power supplies and motor drives. |
| –40°C to 85°C specified range | Guarantees full electrical performance without test extrapolation-no "characterized but not tested" ambiguity. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the maximum common-mode voltage the LTC6101HVBCS5#TRPBF can withstand?
The LTC6101HVBCS5#TRPBF has an absolute maximum total supply voltage (V+ to V–) rating of 105 V, enabling reliable operation in 48 V, 60 V, and 96 V systems with margin for transients. Its internal architecture rejects common-mode voltages up to this limit without damage or specification violation, provided V+ and V– remain within absolute ratings and proper PCB creepage/clearance is maintained.
How does the LTC6101HVBCS5#TRPBF achieve high accuracy with low shunt resistor values?
The LTC6101HVBCS5#TRPBF achieves high accuracy with low-value shunts (e.g., 1–10 mΩ) through its ±450 µV max input offset voltage, 170 nA max input bias current, and Kelvin-input architecture. These specs minimize voltage errors introduced by trace resistance and shunt self-heating, allowing full-scale sensing at 500 mV even with milliohm-level resistors-reducing power loss and thermal drift in the measurement path.
Can the LTC6101HVBCS5#TRPBF be used in bidirectional current sensing applications?
No-the LTC6101HVBCS5#TRPBF is designed exclusively for unidirectional high-side current sensing. Its internal topology sources output current only in one direction and lacks the rail-to-rail input common-mode range or dual-supply capability needed for true bidirectional operation. For bidirectional sensing, consider dedicated devices such as the LTC6102 or INA226.
What is the recommended RIN/ROUT configuration for 100× gain with 5 V output full scale?
For 100× gain and 5 V output at full-scale 50 mV sense voltage, use RIN = 100 Ω and ROUT = 10 kΩ. This yields IOUT = 50 mV / 100 Ω = 500 µA, and VOUT = 500 µA × 10 kΩ = 5 V. Ensure RIN is placed close to the device with Kelvin traces, and ROUT is connected directly from OUT to V– to avoid loading errors.
Does the LTC6101HVBCS5#TRPBF require external compensation capacitors?
No-LTC6101HVBCS5#TRPBF is internally compensated and stable with standard RIN/ROUT configurations. However, if driving capacitive loads >100 pF (e.g., long cables or ADC input filters), a small series resistor (10–50 Ω) between OUT and ROUT is recommended to maintain phase margin and prevent peaking or oscillation observed in typical performance curves.
