Product details
Overview
TSC2011HYDT from STMicroelectronics is a precision bidirectional current sense amplifier with 60 V/V fixed gain, -20 to +70 V wide common-mode input range, ±200 µV max offset voltage, and SO8 package. It operates from 2.7–5.5 V supply across -40 to +150 °C, enabling accurate high- and low-side sensing in motor control feedback loops where shunt-based current measurement must tolerate harsh voltage transients.
For engineers reviewing the TSC2011HYDT datasheet, TSC2011HYDT pinout, TSC2011HYDT application, or TSC2011HYDT equivalent, this page delivers verified specifications, validated pin functions, confirmed industrial use cases, and technically differentiated alternatives - all grounded in STMicroelectronics' DS13791 Rev 2 (Feb 2025) and official parametric data.
Technical Context
The TSC2011HYDT uses a precision instrumentation amplifier topology with rail-to-rail output stage and internal laser-trimmed resistors to achieve 0.3% max gain error and 5 µV/°C max offset drift. Its dual reference inputs (VREF1/VREF2) support ratiometric operation and bidirectional zero-center output alignment.
It integrates active shutdown (active-high SHDN), delivering 20 µA quiescent current in sleep mode while maintaining full common-mode rejection (≥80 dB DC CMR) and stable small-signal bandwidth (500 kHz typical at 5 V). Input bias currents remain within ±600 µA across -20 to +70 V VICM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | 60 V/V - fixed ratio converts 40.5 mV full-scale shunt differential voltage to 2.43 V output swing at 5 V supply. |
| Common-Mode Range | -20 V to +70 V - supports direct sensing on high-side switches in 48 V industrial buses or low-side configurations with negative return paths. |
| Offset Voltage | ±200 µV max (RTI) - enables sub-1% error measurement of ≤100 mA through 10 mΩ shunt at room temperature. |
| Supply Voltage | 2.7–5.5 V - interoperable with 3.3 V microcontrollers and 5 V analog front-ends without level-shifting. |
| Operating Temperature | -40 °C to +150 °C - qualified for under-hood automotive motor drivers and industrial inverters requiring extended thermal margin. |
| Shutdown Current | 20 µA max - reduces system standby power in battery-backed or energy-sensitive applications. |
| Small-Signal Bandwidth | 500 kHz (typical at 5 V) - sufficient for PWM-based current loop sampling up to 20 kHz switching frequencies with <1° phase lag. |
Pinout & Package
SO8 package (ECOPACK2, RoHS-compliant, 1.27 mm pitch), thermally enhanced for continuous operation at 150 °C ambient in enclosed enclosures.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN- | Negative shunt voltage input | Accepts voltage down to -25 V absolute max; requires external series resistor if driven beyond supply rails. |
| 2 GND | Analog ground reference | Shared with PCB ground plane; separate from power ground recommended for noise-sensitive layouts. |
| 3 VREF2 | Secondary reference input | Used with VREF1 to set output center point; tied together for unidirectional mode or split for bidirectional zero-center output. |
| 4 SHDN | Active-high shutdown control | Drives device into 20 µA sleep state; 0.7×VCC min logic high threshold ensures compatibility with 3.3 V GPIOs. |
| 5 OUT | Amplified current-sense output | Rail-to-rail output drives ADC inputs directly; 25 mA sink/source capability supports 10 kΩ load without droop. |
| 6 VCC | Positive supply input | Decoupling capacitor (100 nF ceramic) required within 5 mm of pin to suppress PSRR degradation above 10 kHz. |
| 7 VREF1 | Primary reference input | Configures output offset; applying VCC/2 yields ±2.5 V bidirectional range when VCC = 5 V. |
| 8 IN+ | Positive shunt voltage input | Differential pair input with ±7 V max differential voltage; matched to IN- for >90 dB CMR at DC. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional sensing capability | Output centered at VREF1/VREF2 voltage - enables real-time monitoring of charging/discharging or forward/reverse motor current. |
| High common-mode transient immunity | Recovery time <2 µs after 50 V step (Fig. 44) - maintains accuracy during IGBT switching edge-induced dV/dt noise. |
| Low-drift precision over temperature | 5 µV/°C max offset drift - limits current measurement error to <0.5% over full -40 to +150 °C range with 10 mΩ shunt. |
| Ratiometric reference architecture | 0.1% RTO accuracy with parallel VREF1/VREF2 - eliminates gain error from reference voltage tolerance in ADC-coupled systems. |
| Robust ESD protection | 2000 V HBM / 1000 V CDM - survives handling and board-level transients without external TVS diodes in most industrial environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional current sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| INA240A1QDRQ1 | Gain = 20 V/V; wider common-mode (-4 to +80 V); higher quiescent current (2.4 mA) | Better suited for 80 V battery systems but lacks TSC2011's 150 °C rating and 20 µA shutdown mode | Select for automotive 12 V/48 V hybrid systems needing AEC-Q100 qualification; avoid where ultra-low standby power is critical. |
| MAX40056ATA+T | Gain = 50 V/V; lower offset (±50 µV); narrower temp range (-40 to +125 °C) | Higher precision at room temperature but derates faster above 105 °C; no integrated shutdown | Prefer for lab-grade test equipment or medical devices requiring sub-0.1% linearity; not recommended for under-hood deployment. |
Compared with INA240A1QDRQ1 and MAX40056ATA+T, the TSC2011HYDT uniquely balances 150 °C operation, 20 µA shutdown, and 60 V/V gain optimized for 40–50 mV shunt drops - making it the only choice for thermally constrained industrial motor drives requiring both precision and robustness.

FAQ
What is the maximum allowable differential input voltage for TSC2011HYDT?
The absolute maximum differential voltage between IN+ and IN− is ±7 V per Table 2 of DS13791 Rev 2. Exceeding this risks permanent damage to the input ESD structure. For applications with expected transients above 7 V, external clamping diodes referenced to VCC and GND are required - the internal protection circuitry does not extend beyond this limit.
Can TSC2011HYDT be used with a single-ended reference voltage?
Yes - tie VREF1 and VREF2 together and apply a fixed DC voltage (e.g., 2.5 V) to configure unidirectional output scaling. The device supports ratiometric operation (VREF = VCC/2) or absolute reference; however, using VCC/2 ensures output remains proportional to supply variations, simplifying ADC interfacing in non-regulated systems.
How does shutdown mode affect output behavior?
When SHDN is pulled low, the output (OUT) enters high-impedance state with leakage current ≤50 nA - it does not clamp or drive to rail. This allows multiple TSC2011HYDT devices to share a common ADC input bus without contention. Turn-off time is 4 µs (max), ensuring rapid entry into low-power state during idle cycles.
Is layout guidance available for minimizing noise in high-CMR operation?
Yes - STMicroelectronics AN5025 recommends symmetric 5-mm trace routing for IN+/IN− with ground guard ring, localized 100 nF VCC decoupling, and separation of analog and digital grounds at a single-point star connection near GND pin 2. Avoid routing IN+/IN− near switching nodes or clock traces to preserve >80 dB CMR performance.
