Product details
Overview
TSC210IYCT from STMicroelectronics is a high-precision, zero-drift current sense amplifier optimized for bidirectional or unidirectional shunt-based current measurement in high-common-mode-voltage systems. It features 200 V/V fixed gain, ±35 µV max offset voltage at 25 °C, -0.3 to 26 V input common-mode range, and operates from 2.7 to 26 V supply across -40 to 125 °C - enabling accurate sensing in battery chargers and telecom power rails.
For engineers reviewing the TSC210IYCT datasheet, TSC210IYCT pinout, TSC210IYCT application, or TSC210IYCT equivalent, key selection criteria include its SC70-6/QFN10 package options, REF-pin programmable output common-mode level, guaranteed gain error ≤±1%, 0.1 µV/°C offset drift, and compatibility with low-side/high-side configurations requiring sub-millivolt-level sensing fidelity.
Technical Context
The TSC210IYCT employs a proprietary zero-drift chopper-stabilized architecture with thin-film resistors to achieve <35 µV offset and <0.1 µV/°C drift, enabling stable DC-coupled current measurement over temperature. Its input stage draws bias current from the common-mode rail when Vicm > 2.5 V, allowing operation beyond supply rails.
Output common-mode voltage is set via the REF pin (0–VCC), supporting unidirectional (GND- or VCC-referenced) and bidirectional (mid-rail referenced) configurations. Gain is fixed at 200 V/V by internal 1 MΩ/5 kΩ resistor network, eliminating external gain-setting components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | 200 V/V - fixed internal ratio enables precise, no-component current-to-voltage conversion without gain error from external resistors. |
| Offset Voltage (max) | ±35 µV at 25 °C - ensures ≤0.175 mV output error at full-scale 10 mV shunt drop, critical for sub-ampere current resolution. |
| Common-Mode Range | -0.3 to +26 V - supports direct connection to high-side battery terminals or telecom 48 V rails without level-shifting circuitry. |
| Supply Voltage Range | 2.7 to 26 V - matches wide-input power management ICs and eliminates need for auxiliary LDOs in industrial systems. |
| Quiescent Current | 100 µA - enables always-on current monitoring in battery-powered equipment with minimal standby power penalty. |
| CMRR (min) | 105 dB - rejects >99.999% of common-mode noise from noisy DC-DC converters, preserving signal integrity in dense PCB layouts. |
| Bandwidth | 25 kHz - sufficient for real-time overcurrent protection and closed-loop feedback in motor drives and SMPS. |
Pinout & Package
Available in SC70-6 (1.6 × 1.6 mm) and QFN10 (1.8 × 1.4 mm) packages; both support reflow soldering and offer thermal resistance of 232 °C/W (SC70-6) or 124 °C/W (QFN10).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| REF | Reference voltage input | Sets output common-mode level: GND = unidirectional low-side, VCC = unidirectional high-side, mid-rail = bidirectional sensing. |
| GND | Ground reference | Return path for internal circuitry and output stage; must be low-impedance to maintain CMRR and noise immunity. |
| VCC | Positive supply | Primary power source; device also draws auxiliary current from Vicm rail when >2.5 V, enabling rail-to-rail common-mode operation. |
| VIN+ | Non-inverting input | Connects to high-potential side of shunt; input bias current (≤35 µA) must be accounted for in ultra-low-current designs. |
| VIN− | Inverting input | Connects to low-potential side of shunt; differential input accepts ±26 V max swing, supporting reverse-current detection. |
| OUT | Amplified output | Single-ended output scaled by 200×; swing ranges from 5 mV above GND to VCC − 0.05 V, compatible with 12-bit ADC inputs. |
| NC | No-connect terminal | Unused pins (SC70-6 Pin 1; QFN10 Pins 7 & 8) - must remain floating or tied to GND/VCC per layout guidelines to avoid parasitic coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | Eliminates 1/f noise and thermal drift, enabling stable µV-level offset performance over -40 to 125 °C without calibration. |
| Programmable output common-mode | REF pin allows flexible interface to ADCs: GND-referenced for single-supply systems, VCC-referenced for high-side sensing, or mid-rail for bidirectional current flow. |
| High common-mode rejection | 105 dB min CMRR ensures accurate current reading even when shunt sits on noisy 48 V bus with fast-switching transients. |
| Rail-to-rail input capability | Accepts inputs down to -0.3 V below GND and up to 26 V above GND - supports ground-referenced low-side and battery-positive high-side configurations. |
| Low quiescent power | 100 µA ICC enables continuous current monitoring in energy-sensitive applications like portable medical devices and IoT edge nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar current sense amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| INA240A1IDR | 200 V/V gain, ±5 µV offset (typ), 85 dB CMRR, 4 V/V to 500 V/V adjustable gain via external resistors | Requires external gain-setting resistors; lower CMRR limits noise rejection in high-frequency switcher environments | Select when board space permits external resistors and ultra-low offset is prioritized over CMRR. |
| MAX4080TASA+ | 200 V/V gain, ±100 µV offset (max), 100 dB CMRR, 2.7–76 V supply, SO8 package | Larger SO8 footprint; higher offset reduces resolution in sub-ampere sensing; wider supply supports 48 V telecom directly | Select when 76 V absolute max supply rating is required and SC70/QFN size constraints are relaxed. |
Compared with INA240A1IDR and MAX4080TASA+, the TSC210IYCT delivers superior CMRR (105 dB vs. 85/100 dB) and tighter offset drift (0.1 µV/°C vs. 0.3/0.5 µV/°C), making it optimal for high-accuracy, thermally demanding industrial current loops where layout-induced noise dominates.

FAQ
What is the maximum common-mode voltage the TSC210IYCT can handle?
The TSC210IYCT supports a common-mode input voltage range of -0.3 V to +26 V, independent of supply voltage. This allows direct connection to high-side points in 24 V industrial systems or negative-rail circuits without attenuation or level-shifting networks. Operation beyond 26 V risks permanent damage per absolute maximum ratings.
Can the TSC210IYCT be used for bidirectional current sensing?
Yes - by applying a mid-supply voltage (e.g., VCC/2) to the REF pin, the output common-mode is centered, enabling symmetric positive/negative output swing for forward/reverse current detection. The device's ±26 V differential input range and rail-to-rail output support full-scale bidirectional measurement without external op-amps.
How does the REF pin affect output behavior?
The REF pin sets the output's DC common-mode level: grounding REF yields GND-referenced output (ideal for low-side sensing); tying REF to VCC gives VCC-referenced output (for high-side); and applying an external voltage (e.g., 2.5 V) configures bidirectional operation. Output swing remains within 5 mV of GND and 50 mV below VCC regardless of REF setting.
Is the TSC210IYCT compatible with SC70-6 and QFN10 PCB footprints?
Yes - the TSC210IYCT is offered in both SC70-6 (1.6 × 1.6 mm) and QFN10 (1.8 × 1.4 mm) packages with distinct pinouts. Designers must select the correct footprint and routing: SC70-6 uses 6 pins (REF, GND, VCC, VIN+, VIN−, OUT), while QFN10 adds NC pins and splits VIN+/VIN− across two terminals each for improved layout symmetry and thermal performance.
