Product details
Overview
LTC6101VHVAHS5#TRMPBF from Analog Devices is a high-voltage, high-side current sense amplifier in 5-lead TSOT-23 package with HV pinout configuration. It operates from 5V to 100V supply, delivers ≤300µV max input offset voltage, supports 1µs step response, and provides ground-referenced current-output interface for precision shunt monitoring in automotive battery management systems.
For engineers reviewing the LTC6101VHVAHS5#TRMPBF datasheet, LTC6101VHVAHS5#TRMPBF pinout, LTC6101VHVAHS5#TRMPBF application, or LTC6101VHVAHS5#TRMPBF equivalent, key selection criteria include high common-mode voltage tolerance (up to 100V), low quiescent current (230µA at 12V), −40°C to 125°C operating temperature range, and configurable gain via external RIN/ROUT.
Technical Context
The LTC6101VHVAHS5#TRMPBF uses a high-impedance feedback loop to force −IN to match +IN potential, enabling accurate VSENSE measurement across an external shunt. Its transconductance architecture converts sensed voltage into proportional output current (IOUT = VSENSE/RIN), eliminating common-mode rejection limitations of voltage-output amplifiers.
It features internal MOSFET-based current sourcing to OUT, supports Kelvin-connected shunts to minimize PCB trace error, and maintains 118dB minimum PSRR across 5V–100V supply range. The HV pinout variant isolates V+ and OUT pins for enhanced creepage/clearance in high-voltage applications.
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 small-value shunts (e.g., 5mΩ) while maintaining <1% error at 1A load. |
| Step Response Time | 1µs (to 2.5V on 5V output step) - supports fast overcurrent detection and protection in power supplies. |
| PSRR | 118dB min - rejects supply noise in noisy environments like motor drives or DC-DC converters. |
| Supply Current | 230µA typical at 12V - minimizes self-heating and preserves system efficiency in always-on monitoring. |
| Operating Temp | −40°C to 125°C - qualified for under-hood automotive and industrial control cabinet deployment. |
| Max Sense Voltage | 500mV full-scale - sets upper bound on shunt voltage drop, limiting I²R loss and thermal drift. |
Pinout & Package
Package: 5-Lead Plastic TSOT-23 (HV Pinout), 1mm profile, lead-free finish. Pin spacing optimized for ≥100V working voltage clearance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN | High-side shunt connection | Connected directly to load-side terminal of sense resistor; forms Kelvin sense node for accuracy. |
| −IN | Feedback reference input | Internally driven to match +IN potential; external RIN from V+ sets transconductance gain. |
| V+ | Positive supply input | Supplies device current; must be connected to more positive side of shunt to exclude IC current from measurement. |
| OUT | Current output | Sources IOUT = VSENSE/RIN; requires external ROUT to ground to generate VOUT = IOUT × ROUT. |
| V− | Negative supply / ground | Reference return for output current and internal circuitry; tied to system ground in single-supply operation. |
Key Features
| Feature | Design Value |
|---|---|
| HV-specific pinout | Physical separation between V+ and OUT pins meets IPC-2221B creepage requirements for >100V applications. |
| Configurable gain | Gain = ROUT/RIN set by external resistors - enables flexible scaling (e.g., 20× to 100×) without changing IC. |
| Low input bias current | 170nA max - reduces error from PCB leakage and high-RIN configurations in precision sensing. |
| Ground-referenced output | Output current sourced to V− - eliminates need for isolated ADC or level-shifting circuitry. |
| Wide temp range support | Specified over −40°C to 125°C - ensures stable offset and gain performance in engine bay or factory floor environments. |

FAQ
What is the maximum supply voltage rating for the LTC6101VHVAHS5#TRMPBF?
The LTC6101VHVAHS5#TRMPBF has an absolute maximum supply voltage of 105V between V+ and V− pins, with continuous operation specified from 5V to 100V. This rating enables direct integration into 72V industrial buses and 96V telecom systems without external voltage clamping or regulation.
How does the HV pinout configuration of the LTC6101VHVAHS5#TRMPBF improve reliability?
The HV pinout of the LTC6101VHVAHS5#TRMPBF physically separates V+ and OUT pins on the TSOT-23 package to increase creepage and clearance distances. This design meets IPC-2221B requirements for ≥100V working voltage, reducing risk of arcing or tracking in humid or dusty environments where standard pinouts would fail.
Can the LTC6101VHVAHS5#TRMPBF measure bidirectional current?
No, the LTC6101VHVAHS5#TRMPBF is a unidirectional high-side current sense amplifier. Its architecture sources output current only in one direction (from OUT to V−), and its input stage is optimized for positive VSENSE (i.e., +IN more positive than −IN). Bidirectional sensing requires separate devices like the LTC6102 or discrete op-amp solutions.
What is the recommended RIN value for achieving 100× gain with the LTC6101VHVAHS5#TRMPBF?
To achieve 100× gain with the LTC6101VHVAHS5#TRMPBF, use RIN = 100Ω (standard 1% value), paired with ROUT = 10kΩ. This yields IOUT = VSENSE/100Ω and VOUT = IOUT × 10kΩ = VSENSE × 100, delivering 5V output at 50mV sense voltage - matching the device's 500mV full-scale input limit.
Does the LTC6101VHVAHS5#TRMPBF require external compensation capacitors?
No, the LTC6101VHVAHS5#TRMPBF is internally compensated and stable with standard RIN/ROUT configurations. External capacitors are only needed if driving capacitive loads >1000pF - in which case a 10Ω series resistor between OUT and CLOAD restores stability, as verified in Figure 6101 G15 of the datasheet.
