Product details
Overview
TSC2010HYDT from STMicroelectronics is a precision bidirectional current sense amplifier with 20 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 high-accuracy shunt-based current monitoring in high-voltage industrial motor control and solenoid drive circuits.
For engineers reviewing the TSC2010HYDT datasheet, TSC2010HYDT pinout, TSC2010HYDT application, or TSC2010HYDT equivalent, key selection criteria include its 20 V/V gain accuracy (0.3% max error), low 5 µV/°C offset drift, shutdown quiescent current of 20 µA, and validated performance at 123.6 mV full-scale sensing under worst-case temperature and common-mode conditions.
Technical Context
The TSC2010HYDT implements a precision instrumentation amplifier architecture optimized for bidirectional current measurement via external shunt resistors. Its input stage supports differential sensing across -20 to +70 V common-mode voltage independent of supply rail, with ratiometric reference inputs (VREF1/VREF2) enabling flexible output offset adjustment from 0 to VCC.
It features active high shutdown (SHDN), rail-to-rail output capable of sourcing/sinking ≥25 mA, and stable operation with capacitive loads up to 680 pF. The device maintains ≤0.03% linearity error and 90 dB minimum DC CMRR over full temperature and common-mode range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | 20 V/V - fixed ratio converting shunt voltage to amplified output; enables 123.6 mV full-scale sensing at max error limit. |
| Offset Voltage | ±200 µV max (RTI) - ensures sub-2.5 µA error at 125 mΩ shunt; critical for low-current detection. |
| Common-Mode Range | -20 V to +70 V - supports direct sensing on high-side or low-side of 48 V industrial buses without level-shifting. |
| Supply Voltage | 2.7 V to 5.5 V - compatible with 3.3 V and 5 V logic domains; enables single-supply system integration. |
| Temperature Range | -40 °C to +150 °C - qualified for under-hood automotive actuators and industrial motor drives with extended thermal stress. |
| Shutdown Current | 20 µA max - reduces system standby power in battery-backed or energy-sensitive applications. |
| Bandwidth | 600 kHz (typ, RL=10 kΩ, CL=100 pF) - sufficient for PWM current loop feedback in 20 kHz motor inverters. |
Pinout & Package
Supplied in SO8 (Small Outline, 8-pin) package with standard 1.27 mm pitch, gull-wing leads, and exposed pad for thermal enhancement (RθJA = 125 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN− | Negative input | Connects to shunt resistor low-side; forms differential pair with IN+ for bidirectional current polarity detection. |
| 2 GND | Ground reference | Power and signal ground return; must be low-impedance path to minimize noise coupling into sensitive inputs. |
| 3 VREF2 | Reference voltage 2 | Second ratiometric reference input; used with VREF1 to set output zero point (e.g., VCC/2 for bidirectional operation). |
| 4 SHDN | Shutdown control | Active-high digital enable; pulls output to high-impedance state when low; leakage <1.2 µA at VCC. |
| 5 OUT | Amplified output | Rail-to-rail voltage output proportional to (IN+ − IN−) × 20; drives ADC inputs or comparator thresholds directly. |
| 6 VCC | Positive supply | 2.7–5.5 V analog supply; powers internal amplifiers and bias circuitry; decoupling capacitor required near pin. |
| 7 VREF1 | Reference voltage 1 | Primary ratiometric reference input; parallel connection with VREF2 sets output offset with 0.1% accuracy. |
| 8 IN+ | Positive input | Connects to shunt resistor high-side; differential voltage across IN+ and IN− defines sensed current direction and magnitude. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional sensing | Supports current flow in either direction using VREF1/VREF2 biasing; enables regenerative braking and H-bridge monitoring. |
| High CMRR | ≥90 dB DC CMRR over -20 to +70 V common-mode range - rejects bus noise in noisy industrial environments. |
| Low offset drift | 5 µV/°C max - limits temperature-induced error to <0.75 mV over 150 °C span, preserving calibration stability. |
| Wide supply range | 2.7–5.5 V operation - eliminates need for dedicated LDO in mixed-voltage systems; compatible with Li-ion and 5 V rails. |
| Fast shutdown recovery | 8 µs turn-on time (VCC = 2.7 V) - enables cycle-by-cycle current limiting in high-frequency switching applications. |
Applications

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 | 20 V/V gain, but wider -4 to +80 V common-mode range; higher 120 kHz bandwidth; AEC-Q100 qualified. | Targeted at automotive battery management; lacks VREF1/VREF2 flexibility for user-defined zero-point offset. | Select for automotive-grade reliability where extended common-mode and qualification outweigh programmable offset needs. |
| TSC2011HYDT | 60 V/V gain, identical package/pinout; same temp range and offset specs; 123.6 mV full-scale sensing requires smaller shunt. | Used where higher gain improves SNR for low-current (<1 A) solenoids or sensors with micro-ohm shunts. | Drop-in replacement if system redesign allows lower shunt value; retains all timing, thermal, and interface compatibility. |
Compared with INA240A1QDRQ1, TSC2010HYDT offers superior offset drift (5 vs. 10 µV/°C) and configurable ratiometric offset, while TSC2011HYDT provides identical form-factor scaling for higher sensitivity-both alternatives preserve SO8 footprint but differ in gain and application focus.

FAQ
What is the maximum shunt resistance supported for accurate 20 A measurement?
At 20 A full-scale and 123.6 mV sense voltage, the maximum shunt resistance is 6.18 mΩ. This value ensures gain error remains ≤0.3% across -40 to +150 °C, verified per DS13791 Table 4 at VCC = 2.7 V and VICM = 12 V.
Can TSC2010HYDT operate with VREF1 and VREF2 unconnected?
No. Both VREF1 and VREF2 must be connected to the same reference voltage (e.g., VCC/2) to establish proper output offset. Leaving either pin floating causes undefined output behavior and violates absolute maximum ratings for input voltage.
How does the device handle common-mode transients above 70 V?
The absolute maximum common-mode rating is 76 V (Table 2). Transients exceeding +70 V or below -20 V risk permanent damage. External clamping (e.g., TVS diodes) is required for IEC 61000-4-4/5 surge immunity beyond rated limits.
Is the SO8 package thermally enhanced?
Yes. The SO8 package includes an exposed thermal pad (EP) on the underside, recommended for soldering to PCB copper pour to achieve RθJA = 125 °C/W. Thermal design guidelines are provided in DS13791 Section 7.2.
