Product details
Overview
TSC210ICT from STMicroelectronics is a high-precision, zero-drift current sense amplifier optimized for bidirectional or unidirectional shunt-based current measurement across -0.3 V to +26 V common-mode voltage range. It delivers 200 V/V fixed gain, ±35 µV max offset voltage at 25 °C, 0.1 µV/°C max offset drift, and operates from 2.7 V to 26 V supply - enabling accurate sensing in battery chargers and telecom power rails.
For engineers reviewing the TSC210ICT datasheet, TSC210ICT pinout, TSC210ICT application, or TSC210ICT equivalent, key selection criteria include its SC70-6/QFN10 package options, REF-pin programmable output common-mode level, guaranteed ±1% gain error over -40 °C to +125 °C, and ability to operate with input common-mode voltage exceeding supply rail.
Technical Context
The TSC210ICT employs a proprietary zero-drift chopper-stabilized architecture with thin-film resistors to achieve ultra-low offset and drift. Its input stage draws bias current from the common-mode rail when Vicm > 2.5 V, enabling operation beyond the VCC supply range - critical for high-side sensing in 12 V or 24 V systems.
Output common-mode voltage is set via the REF pin, supporting ground-referenced (unidirectional), VCC-referenced (unidirectional), or mid-supply-referenced (bidirectional) configurations. CMRR exceeds 105 dB (TSC210) and PSRR remains below 10 µV/V across 2.7–26 V supply variation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | 200 V/V - fixed ratio enabling precise scaling of mV-level shunt voltage to measurable output voltage |
| Offset voltage (max) | ±35 µV at 25 °C - ensures <0.175 mV error at full-scale 5 mV sense voltage |
| Common-mode range | -0.3 V to +26 V - supports both high-side and low-side shunt placement in 24 V industrial or telecom systems |
| Supply voltage range | 2.7 V to 26 V - allows direct operation from Li-ion battery, 3.3 V logic, or 24 V bus without LDO |
| Quiescent current | 100 µA - enables always-on current monitoring in power-constrained portable equipment |
| Gain error (max) | ±1% - limits full-scale current measurement error to ≤1% independent of temperature or supply |
| Operating temperature | -40 °C to +125 °C - qualified for under-hood automotive, industrial motor control, and base station environments |
Pinout & Package
Available in SC70-6 (1.6 × 1.6 mm) and QFN10 (1.8 × 1.4 mm, 0.5 mm pitch) packages. Both variants support identical functionality and pin mapping per DS13237 Rev 7.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| REF | Reference voltage input | Sets output common-mode level; enables unidirectional (GND/VCC) or bidirectional (mid-rail) operation |
| GND | Ground reference | Return path for internal circuitry and output stage; must be low-impedance for noise immunity |
| VCC | Power supply | Primary supply rail; device also draws auxiliary current from VIN+ when common-mode > 2.5 V |
| VIN+ | Non-inverting input | Connects to high-side of shunt resistor; accepts up to +26 V common-mode voltage |
| VIN- | Inverting input | Connects to low-side of shunt resistor; differential input handles ±26 V max swing |
| OUT | Amplified output | Single-ended output scaled by 200×; swing ranges from 30 mV above GND to 0.2 V below VCC |
| NC | No-connect terminal | QFN10 pins 1 & 7 and SC70-6 pin 1 are unused; may be left floating or tied to GND/VCC |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | Eliminates 1/f noise and thermal drift - maintains ±35 µV offset stability across -40 °C to +125 °C |
| Extended common-mode range | -0.3 V to +26 V - enables direct high-side sensing on 24 V bus without level-shifting circuitry |
| REF-pin programmability | Configures output for unidirectional (0 V or VCC) or bidirectional (any VREF between GND–VCC) current flow detection |
| High CMRR | 105 dB min - rejects interference from noisy power rails during precision shunt voltage amplification |
| Low quiescent current | 100 µA - supports continuous current monitoring in battery-powered notebook and portable test equipment |

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, ±10 µV offset (typ), 2.7–5.5 V supply only | Limited to low-voltage systems; cannot support >5.5 V common-mode or supply | Select when operating strictly within 3.3 V/5 V domains and ultra-low offset is prioritized over voltage range |
| MAX40056ATA+T | 200 V/V gain, ±50 µV offset (max), 2.7–5.5 V supply, 1.5 MHz BW | Higher bandwidth but narrower common-mode (-0.2 V to +5.5 V) and supply range | Prefer for high-speed transient current capture in 5 V embedded controllers where 26 V operation is unnecessary |
Compared with INA240A1IDR and MAX40056ATA+T, the TSC210ICT uniquely supports 26 V common-mode and supply operation while maintaining ±35 µV offset - making it the only option for direct high-side sensing in 24 V industrial or telecom infrastructure without auxiliary supplies.

FAQ
What is the maximum common-mode voltage the TSC210ICT can handle?
The TSC210ICT supports a common-mode input voltage range of -0.3 V to +26 V, independent of supply voltage. This allows direct high-side sensing on 24 V buses without level-shifting components. Operation above VCC is enabled by internal bias current drawn from the VIN+ node, as confirmed in DS13237 Section 6.2.
Can the TSC210ICT be used for bidirectional current sensing?
Yes - the REF pin allows configuration for bidirectional operation by applying a mid-supply reference voltage (e.g., VCC/2). This centers the output at VCC/2, enabling symmetric positive/negative output swing for forward/reverse current detection, as detailed in DS13237 Section 6.3.
What package options are available for the TSC210ICT?
The TSC210ICT is offered in SC70-6 (1.6 × 1.6 mm) and QFN10 (1.8 × 1.4 mm) packages. Pin functions are identical across both variants per Figure 1 and Table 1 of DS13237 Rev 7, with NC pins clearly defined for each footprint.
How does the REF pin affect output behavior?
The REF pin sets the output common-mode voltage: grounding REF yields 0 V quiescent output (unidirectional), connecting to VCC yields VCC quiescent output (unidirectional), and applying mid-rail voltage enables bidirectional swing. Output is referenced differentially to REF for optimal CMRR, as specified in DS13237 Section 6.2.
