Product details
Overview
LTC6101VHVBHS5#TRMPBF from Analog Devices is a high-voltage, high-side current sense amplifier in 5-lead TSOT-23 package with HV pinout configuration, operating from 5V to 100V supply, featuring 300μV max input offset voltage, 1μs step response, and ±170nA max input bias current. It enables precise shunt-based load current monitoring in automotive battery management and industrial power supplies where common-mode voltage exceeds 60V.
For engineers reviewing the LTC6101VHVBHS5#TRMPBF datasheet, LTC6101VHVBHS5#TRMPBF pinout, LTC6101VHVBHS5#TRMPBF application, or LTC6101VHVBHS5#TRMPBF equivalent, this page delivers verified specifications, thermal-grade packaging (–40°C to 125°C), gain-setting resistor design guidance, and validated alternatives for high-voltage current sensing systems.
Technical Context
The LTC6101VHVBHS5#TRMPBF uses a transconductance architecture: its internal amplifier forces –IN to match +IN potential, enabling VSENSE across an external shunt to generate output current IOUT = VSENSE/RIN. This current is converted to ground-referenced voltage via ROUT, supporting unidirectional analog output into ADCs like LTC2433-1.
It operates with 118dB min PSRR over 5V–100V supply range and supports Kelvin-sense connections to reject PCB trace resistance errors. Its HV pinout (V+ on pin 3, OUT on pin 5) provides enhanced creepage for >100V absolute maximum operation, distinct from standard S5 pinout variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 5V to 100V - supports direct connection to 48V/72V/96V bus systems without level-shifting. |
| Input Offset Voltage | ±300μV max - enables use of low-value shunts (e.g., 5mΩ) while maintaining <1% error at 1A load. |
| Step Response Time | 1μs - detects fast overcurrent events for real-time protection in motor drives and DC-DC converters. |
| Input Bias Current | ±170nA max - minimizes voltage drop error across high-value RIN resistors used for low-gain configurations. |
| PSRR | 118dB min - rejects supply ripple in noisy industrial environments without additional filtering. |
| Operating Temp | –40°C to 125°C - qualified for under-hood automotive and industrial control cabinet applications. |
| Max Sense Voltage | 500mV - defines full-scale shunt voltage, allowing dynamic range optimization up to 70dB. |
Pinout & Package
Package: 5-Lead Plastic TSOT-23 HV Pinout (LTHHD marking), 1mm profile, rated for high-voltage spacing per IEC 61000-4-5.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN | Non-inverting input | Connected to load side of shunt; must be Kelvin-wired to avoid trace IR error. |
| –IN | Inverting input | Driven to same potential as +IN; tied to V+ via RIN to set transconductance gain. |
| V+ | Positive supply | Accepts 5V–100V; supply current flows through this pin; connects to high-side of shunt for load-only current sensing. |
| V– | Negative supply / ground | Reference for output voltage; tied to system ground when using single-supply configuration. |
| OUT | Current output | Sources IOUT = VSENSE/RIN; requires external ROUT to ground to generate VOUT = IOUT × ROUT. |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage pinout layout | Separates V+ and OUT with increased creepage distance to support 105V absolute max rating and reduce arcing risk. |
| Low quiescent current | 350μA typical at 12V - reduces self-heating and power loss in always-on battery monitoring circuits. |
| Configurable gain | Set by external RIN/ROUT pair - enables flexible scaling (e.g., 20× to 100×) without changing IC. |
| Ground-referenced output | Eliminates need for isolated amplifiers or level shifters when interfacing with standard ADCs or microcontrollers. |
| Wide temperature specification | –40°C to 125°C operating range - meets AEC-Q100 Grade 1 requirements for automotive powertrain modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage high-side current sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX40056ASA+T | Fixed 50V/V gain, 2.7V–60V supply, 1.5μs response, ±125μV offset | Requires no external RIN/ROUT; limited to lower supply range than LTC6101VHVBHS5#TRMPBF | Select when gain stability and board space are prioritized over supply voltage flexibility. |

FAQ
What is the absolute maximum supply voltage rating for LTC6101VHVBHS5#TRMPBF?
The LTC6101VHVBHS5#TRMPBF has an absolute maximum total supply voltage (V+ to V–) of 105V, as specified in the Absolute Maximum Ratings table. This allows safe operation in 96V battery systems with margin for transients. Operation beyond 100V continuous supply is not recommended, and the device is characterized from 5V to 100V per its electrical specifications. The 105V limit applies only to short-duration transients per IEC 61000-4-5 standards.
How does the HV pinout of LTC6101VHVBHS5#TRMPBF differ from standard S5 packages?
The LTC6101VHVBHS5#TRMPBF uses the LTHHD-marked HV pinout (V+ on pin 3, OUT on pin 5), which increases creepage distance between high-voltage pins compared to standard S5 variants. This layout meets reinforced insulation requirements for >100V working voltages and prevents arcing in high-density PCBs. Standard S5 parts use different pin assignments (e.g., V+ on pin 5), making them incompatible without layout revision.
Can LTC6101VHVBHS5#TRMPBF measure bidirectional current?
No, the LTC6101VHVBHS5#TRMPBF is a unidirectional high-side current sense amplifier optimized for positive-load-current detection only. Its output current flows exclusively from OUT to V–, producing a ground-referenced voltage proportional to forward shunt voltage. For bidirectional sensing, Analog Devices recommends the INA240 series or discrete solutions with dual amplifiers; the LTC6101VHVBHS5#TRMPBF does not support negative VSENSE or reverse current reporting.
What is the minimum recommended RIN value for LTC6101VHVBHS5#TRMPBF at 100V supply?
At 100V supply, the LTC6101VHVBHS5#TRMPBF's maximum output current is 1mA. To avoid exceeding this limit with 500mV full-scale VSENSE, RIN must be ≥500Ω (since IOUT = VSENSE/RIN). A 499Ω 1% resistor is commonly used for 100× gain configurations. Lower RIN values increase output current and may cause thermal stress or violate the 1mA absolute maximum rating if VSENSE exceeds 500mV.
Does LTC6101VHVBHS5#TRMPBF require external compensation components?
No, the LTC6101VHVBHS5#TRMPBF is internally compensated and operates stably with standard RIN/ROUT configurations. No external capacitors or resistors are needed for frequency compensation. However, a 1000pF capacitor from OUT to V– is recommended when driving capacitive loads >100pF (e.g., long traces or ADC inputs) to prevent peaking or oscillation, as shown in Figure G15 of the datasheet.
