Product details
Overview
LTC6101VHVAIS5#TRMPBF from Analog Devices is a high-voltage, high-side current sense amplifier in 5-lead TSOT-23 package with HV pinout. It operates from 5V to 100V supply, delivers 1µs step response, supports ±300µV max input offset voltage, and provides configurable gain via external RIN/ROUT resistors for precision load current monitoring in automotive battery management systems.
For engineers reviewing the LTC6101VHVAIS5#TRMPBF datasheet, LTC6101VHVAIS5#TRMPBF pinout, LTC6101VHVAIS5#TRMPBF application, or LTC6101VHVAIS5#TRMPBF equivalent, key selection criteria include high common-mode voltage tolerance (up to 100V), low quiescent current (350µA at 12V), –40°C to 85°C operating temperature range, and compatibility with Kelvin-sense shunt configurations for <1% measurement error.
Technical Context
The LTC6101VHVAIS5#TRMPBF uses a transconductance architecture where VSENSE across an external shunt resistor controls output current IOUT = VSENSE/RIN, enabling ground-referenced voltage output via ROUT. Its internal amplifier forces –IN to track +IN, eliminating common-mode rejection dependency on resistor matching.
It features 118dB minimum PSRR over 5V–100V supply range, 140kHz signal bandwidth at 200µA load, and absolute maximum 105V total supply voltage. The HV pinout variant ensures adequate creepage/clearance for >100V applications, distinguishing it from standard S5 variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 5V to 100V - enables direct monitoring of 48V/60V/72V industrial and automotive bus voltages without level-shifting. |
| Input Offset Voltage | ±300µV max - allows use of 50mΩ shunt at 1A full-scale while limiting offset-induced error to ≤3mA. |
| Step Response Time | 1µs to 2.5V on 5V output step - supports fast overcurrent detection for load protection within microsecond-critical systems. |
| Supply Current | 350µA typical at 12V - reduces self-heating and power budget impact in always-on battery monitoring circuits. |
| PSRR | 118dB min - rejects supply ripple and noise even under wide dynamic bus voltage swings. |
| Input Sense Range | 500mV full-scale - accommodates shunt voltages from 10mV to 500mV, supporting both high-precision low-current and high-power sensing. |
| Operating Temp | –40°C to 85°C - qualified for under-hood automotive and industrial control environments. |
Pinout & Package
Package: 5-lead Plastic TSOT-23 with HV pinout (LTHHD marking), 1mm profile, optimized for high-voltage spacing and thermal performance (θJA = 250°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN | High-side sense input | Connected directly to load-side terminal of shunt; forms Kelvin sense node for accurate VSENSE capture. |
| –IN | Feedback input | Tied to V+ via RIN; internal amplifier forces –IN = +IN, establishing precise transconductance IOUT = VSENSE/RIN. |
| V+ | Positive supply | Supplies device current; connection point determines whether LTC6101VHVAIS5#TRMPBF current is included in sensed load current. |
| V– | Negative supply / ground | Reference for output voltage generation; tied to system ground when used in single-supply configuration. |
| OUT | Current output | Sources proportional current IOUT; converted to voltage by external ROUT to ground for ADC interfacing. |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage pinout layout | Guarantees ≥0.5mm creepage between V+ and –IN pins, meeting IPC-2221 Class B requirements for 100V working voltage. |
| Low input bias current | 170nA max - minimizes error from trace resistance in Kelvin-sense PCB layouts, preserving accuracy down to 10mA load currents. |
| Configurable gain | Set via external RIN/ROUT - enables flexible scaling (e.g., 20× to 100×) without changing IC, reducing BOM count across product variants. |
| Wide temperature specification | –40°C to 85°C guaranteed - eliminates derating concerns in engine control units and telecom rectifiers operating near thermal limits. |
| Fast overload recovery | Indefinite output short-circuit duration to V– - survives accidental grounding of OUT pin during field service or test. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX40056ASA+T | Fixed 50V max supply; 12-bit effective resolution; no HV pinout option. | Limited to ≤50V systems; requires external op-amp for gain adjustment. | Select when cost sensitivity outweighs 100V operation and ultra-low offset requirements. |

FAQ
What is the absolute maximum supply voltage rating for LTC6101VHVAIS5#TRMPBF?
The absolute maximum total supply voltage (V+ to V–) for LTC6101VHVAIS5#TRMPBF is 105V, per the Absolute Maximum Ratings table in the official datasheet. This exceeds its 5V–100V operational range and defines the upper limit before risk of permanent damage. Operation above 100V is not specified or guaranteed, and sustained exposure near 105V may affect long-term reliability.
Does LTC6101VHVAIS5#TRMPBF support Kelvin (4-wire) shunt connections?
Yes, LTC6101VHVAIS5#TRMPBF explicitly supports Kelvin connections: +IN connects to the load-side shunt terminal, and –IN connects to the V+-side shunt terminal via RIN. This topology isolates sense traces from high-current paths, eliminating errors caused by PCB trace resistance-critical for achieving <0.5% accuracy at 10A+ loads.
How is gain configured on LTC6101VHVAIS5#TRMPBF?
Gain on LTC6101VHVAIS5#TRMPBF is set externally using two resistors: RIN from –IN to V+, and ROUT from OUT to V–. Output voltage is VOUT = VSENSE × (ROUT/RIN). Common configurations include RIN = 100Ω/ROUT = 10kΩ for 100× gain, enabling 50mV VSENSE to produce 5V output.
What is the guaranteed operating temperature range for LTC6101VHVAIS5#TRMPBF?
LTC6101VHVAIS5#TRMPBF is guaranteed to operate from –40°C to +85°C, as indicated by the "I" grade suffix and confirmed in the Order Information table. This range covers automotive under-hood, industrial control, and telecom equipment environments without derating.
Can LTC6101VHVAIS5#TRMPBF be used with a 3.3V ADC reference?
Yes, LTC6101VHVAIS5#TRMPBF can interface directly with a 3.3V ADC reference by selecting ROUT to scale VOUT to ≤3.3V at full-scale VSENSE. For example, with VSENSE(MAX) = 500mV and RIN = 100Ω, ROUT = 660Ω yields VOUT = 3.3V - staying within the 1mA max output current and 8V max output voltage limits.
