Product details
Overview
TSC215IYCT from STMicroelectronics is a zero-drift, high-precision 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 75 V/V fixed gain, ±1% max gain error, 0.1 µV/°C max offset drift, 100 µA quiescent current, and operates from 2.7 V to 26 V supply over -40 °C to +125 °C - enabling accurate battery charge/discharge monitoring in portable power systems.
For engineers reviewing the TSC215IYCT datasheet, TSC215IYCT pinout, TSC215IYCT application, or TSC215IYCT equivalent, key selection criteria include its SC70-6/QFN10 dual-package support, REF-pin programmable output common-mode level, 60 kHz bandwidth, 0.42 V/µs slew rate, and guaranteed performance under high common-mode transients in telecom power supplies and industrial motor controllers.
Technical Context
The TSC215IYCT employs a proprietary zero-drift chopper-stabilized instrumentation amplifier architecture with thin-film resistor networks, achieving ±35 µV max input offset (RTI) at 25 °C and 0.3 µV/°C max drift over full temperature range. Its input stage draws bias current from the common-mode rail when Vicm > 2.5 V, enabling operation beyond supply rails.
Output common-mode voltage is set via the REF pin, supporting ground-referenced (unidirectional), VCC-referenced (unidirectional), or externally biased mid-rail (bidirectional) configurations. CMRR exceeds 100 dB up to 100 kHz, and PSRR remains below 10 µV/V across 2.7–26 V supply variation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | 75 V/V - fixed ratio enabling precise scaling of mV-level shunt voltage to measurable output range |
| Common-mode range | −0.3 V to +26 V - supports both high-side and low-side sensing without level-shifting circuitry |
| Offset voltage (RTI) | ±60 µV max - ensures <0.1% error at 10 mV sense voltage, critical for sub-amp current resolution |
| Gain error | ±1% max - guarantees consistent scaling across temperature and supply voltage for closed-loop feedback |
| Bandwidth | 60 kHz - sufficient for fast transient detection in battery protection and DC-DC converter current limiting |
| Quiescent current | 100 µA - enables always-on current monitoring in energy-constrained portable and IoT devices |
| Operating temperature | −40 °C to +125 °C - qualified for automotive body electronics and industrial power modules |
Pinout & Package
Available in SC70-6 (1.6 × 1.6 mm) and QFN10 (1.8 × 1.4 mm) packages; both are surface-mount, lead-free, and RoHS-compliant. Pin functions are identical across packages with minor layout differences.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| REF | Reference voltage input | Sets output common-mode level; enables unidirectional (GND/VCC tie) or bidirectional (mid-rail bias) operation |
| GND | Ground reference | Primary return path for internal circuitry and output stage; must be low-impedance for noise immunity |
| VCC | Power supply | Primary supply rail (2.7–26 V); device also draws auxiliary current from VIN+ when Vicm > 2.5 V |
| VIN+ | Non-inverting input | Connects to high-side or low-side shunt terminal; accepts common-mode voltages beyond VCC/GND |
| VIN− | Inverting input | Connects to opposite shunt terminal; differential pair with VIN+ defines sensed voltage polarity |
| OUT | Analog output | Amplified, rail-to-rail capable output (VCC−0.05 V / GND+30 mV); referenced to REF for optimal CMRR |
| NC | No-connect | Unused pins (SC70-6 Pin 1 & QFN10 Pin 7); must remain floating or tied to GND/VCC per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | Eliminates 1/f noise and thermal drift, enabling stable µV-level offset performance over time and temperature |
| Extended common-mode range | Operates with inputs up to 26 V above GND or 0.3 V below GND - removes need for external level shifters in high-voltage systems |
| REF-pin programmable output | Allows flexible unidirectional or bidirectional current sensing by setting output baseline without external op-amps |
| High CMRR (100–120 dB) | Maintains accuracy in noisy environments (e.g., switch-mode power supplies) where common-mode transients exceed 10 V/µs |
| Low quiescent current | 100 µA enables continuous current monitoring in battery-backed systems with multi-year runtime requirements |

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 | 100 V/V gain, 2.7–5.5 V supply only, no REF pin - requires external bias for bidirectional use | Limited to low-voltage systems; lacks extended common-mode capability for 24–48 V telecom rails | Select when supply is strictly ≤5.5 V and bidirectional operation is not required |
| TSC214IYCT | 100 V/V gain, same package and architecture, ±100 µV max offset (vs. ±60 µV for TSC215) | Higher gain improves small-current sensitivity but reduces dynamic range for large currents | Prefer for applications needing tighter resolution below 1 A, accepting slightly higher offset uncertainty |
Compared with INA240A1IDR, TSC215IYCT supports wider supply (2.7–26 V) and common-mode (−0.3–26 V) ranges without external components; versus TSC214IYCT, it trades 25% lower gain for improved offset spec and better matching in multi-channel current monitoring systems.

FAQ
What is the maximum common-mode voltage the TSC215IYCT can handle?
The TSC215IYCT 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 industrial buses or low-side sensing on negative-grounded 48 V telecom systems without level-shifting circuitry or isolation.
How does the REF pin affect bidirectional current measurement?
The REF pin sets the output common-mode voltage baseline. When biased to VCC/2 (e.g., 2.5 V on 5 V supply), OUT swings symmetrically around that voltage - enabling positive current to produce +VOUT and negative current to produce −VOUT relative to REF, supporting true bidirectional sensing with single-supply ADCs.
Can TSC215IYCT operate with supply voltage below 2.7 V?
No - the absolute minimum supply voltage is 2.7 V per datasheet Absolute Maximum Ratings. Operation below this threshold risks undefined behavior, including failure to power internal amplifiers and loss of rail-to-rail output swing. The device is not characterized or guaranteed below 2.7 V.
What is the recommended PCB layout practice for minimizing noise coupling?
Place the TSC215IYCT as close as possible to the shunt resistor, route VIN+ and VIN− differentially with matched trace lengths and guard ring grounding, decouple VCC with 100 nF ceramic + 1 µF tantalum, and connect REF to a clean, low-impedance source - ideally buffered if derived from a resistive divider.
