Product details
Overview
LTC6101VHVCHS5#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 with –40°C to 125°C temperature range. It enables precise load current monitoring in automotive battery management and industrial power supplies using external RIN/ROUT resistors for configurable gain.
For engineers reviewing the LTC6101VHVCHS5#TRMPBF datasheet, LTC6101VHVCHS5#TRMPBF pinout, LTC6101VHVCHS5#TRMPBF application, or LTC6101VHVCHS5#TRMPBF equivalent, key selection criteria include high common-mode voltage tolerance (105V abs max), low quiescent current (350μA typ at 100V), PSRR ≥118dB, and Kelvin-input compatibility for milliohm-shunt accuracy.
Technical Context
The LTC6101VHVCHS5#TRMPBF uses a transconductance architecture where VSENSE across an external shunt drives output current IOUT = VSENSE/RIN, then converted to ground-referenced VOUT = IOUT × ROUT. Its internal sense amplifier forces –IN to match +IN potential, enabling accurate high-side sensing without level-shifting ICs.
It supports unidirectional current measurement up to 500mV full-scale input, with guaranteed performance over –40°C to 125°C (H-grade), 110–140dB PSRR across 5–100V supply, and 140kHz signal bandwidth at 200μA load-making it suitable for fast overcurrent detection in 48V telecom and EV auxiliary systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 5V to 100V (105V absolute max); enables direct monitoring of 48V/72V/96V bus voltages without external regulators. |
| Input Offset Voltage | ±300μV max (H-grade); allows use of ≤10mΩ shunts while maintaining <1% error at 100mA load. |
| Step Response | 1μs (to 2.5V on 5V output step); supports real-time load current warning and shutdown in <1.5μs. |
| PSRR | ≥118dB min (6–100V); rejects supply ripple in noisy industrial DC buses without additional filtering. |
| Supply Current | 350μA typical at 100V; reduces self-heating and power loss in always-on battery monitoring circuits. |
| Operating Temp | –40°C to 125°C (specified); qualified for under-hood automotive and industrial motor drive environments. |
| Input Sense Range | 0–500mV full scale; accommodates wide dynamic current ranges (e.g., 1mA–10A) with single shunt. |
Pinout & Package
Package: 5-lead Plastic TSOT-23 (ThinSOT™), 1mm profile, HV pinout variant (LTHHD marking), optimized for high-voltage spacing between pins 1 (–IN) and 5 (V–).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN | High-side sense input (positive) | Connected directly to load side of shunt; forms Kelvin sense node for minimal trace resistance error. |
| –IN | High-side sense input (negative) | Driven to same potential as +IN; tied via RIN to V+ to set transconductance gain IOUT = VSENSE/RIN. |
| V+ | Positive supply input | Draws supply current; connection point determines whether LTC6101VHVCHS5#TRMPBF current is included in measurement. |
| V– | Negative supply / ground reference | Serves as return path for output current; must be stable ground or negative rail for bipolar operation. |
| OUT | Current output terminal | Sources proportional current; requires external ROUT to ground to generate analog voltage output VOUT. |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage operation | 105V absolute maximum supply rating enables direct integration into 72V/96V industrial and EV subsystems without isolation. |
| Kelvin-input architecture | Separate +IN/–IN pins eliminate PCB trace resistance errors, supporting sub-10mΩ shunt accuracy in high-current designs. |
| Configurable gain | Gain set by external RIN/ROUT (e.g., 20× to 100×); avoids fixed-gain limitations and allows optimization for resolution vs. dynamic range. |
| Low bias current | 170nA max input bias current minimizes error from shunt resistor mismatch and enables use of high-value RIN for ultra-low-power applications. |
| Fast transient response | 1μs rise time supports cycle-by-cycle overcurrent protection in switching power supplies and motor controllers. |

FAQ
What is the absolute maximum supply voltage rating for the LTC6101VHVCHS5#TRMPBF?
The LTC6101VHVCHS5#TRMPBF has an absolute maximum total supply voltage (V+ to V–) rating of 105V, with recommended operating range from 5V to 100V. Exceeding 105V risks permanent damage per Absolute Maximum Ratings table. This rating enables direct use in 72V and 96V industrial systems without external voltage clamping.
How does the LTC6101VHVCHS5#TRMPBF achieve high-side current sensing without a level-shifter?
The LTC6101VHVCHS5#TRMPBF uses an internal transconductance amplifier that forces the –IN pin to match the +IN pin potential, allowing current through external RIN to generate IOUT = VSENSE/RIN. This current is sourced from OUT to V–, producing a ground-referenced VOUT = IOUT × ROUT-eliminating need for external level-shifting circuitry.
What is the guaranteed operating temperature range for the LTC6101VHVCHS5#TRMPBF?
The LTC6101VHVCHS5#TRMPBF is specified for –40°C to 125°C operation (H-grade), with full electrical performance guaranteed across this range. The device is characterized for reliable function up to 150°C junction temperature, making it suitable for under-hood automotive and industrial motor drive applications.
Can the LTC6101VHVCHS5#TRMPBF be used with a 10mΩ shunt resistor for 0–10A current sensing?
Yes-the LTC6101VHVCHS5#TRMPBF supports 500mV full-scale input, so a 10mΩ shunt yields 100mV at 10A, well within range. With ±300μV max offset, error is ≤0.3% of full scale, and its 170nA max input bias current introduces negligible error. Kelvin connection is recommended to maintain accuracy at high load currents.
What external components are required to configure the LTC6101VHVCHS5#TRMPBF for 50× gain?
To achieve 50× gain with the LTC6101VHVCHS5#TRMPBF, use RIN = 200Ω and ROUT = 10kΩ (per Applications Information Table). This sets IOUT = VSENSE/200 and VOUT = IOUT × 10k = VSENSE × 50. Ensure RIN is placed close to the device with Kelvin traces to minimize parasitic resistance impact on gain accuracy.
