Product details
Overview
ZXCT214QCDW-7 from Diodes Incorporated is an automotive-grade, zero-drift, high-precision current-shunt monitor with 100 V/V fixed gain, ±60 µV max input offset voltage, and ±0.5% max gain error over temperature. It operates from 2.7V to 26V supply, supports common-mode voltages from –0.3V to 26V, and delivers rail-to-rail output for accurate low-side or high-side current sensing in EV battery management systems.
For engineers reviewing the ZXCT214QCDW-7 datasheet, ZXCT214QCDW-7 pinout, ZXCT214QCDW-7 application, or ZXCT214QCDW-7 equivalent, this device is selected for AEC-Q100 Grade 1 automotive designs requiring stable 10mV full-scale shunt sensing, minimal power loss, and operation across –40°C to +125°C ambient conditions.
Technical Context
The ZXCT214QCDW-7 uses a zero-drift chopper-stabilized architecture with post-trim calibration to achieve ±60 µV max offset and 10 ppm/°C max gain drift over full temperature range. Its differential input stage enables precise measurement of shunt voltage drops as low as 10 mV while rejecting common-mode signals up to 26 V.
It features rail-to-rail output swing (within 50 mV of rails), 30 kHz bandwidth at 10 pF load, and 100 µA max quiescent current - enabling integration into low-power, high-voltage automotive subsystems such as e-compressor controllers and OBC current monitoring paths without compromising accuracy or thermal performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | 100 V/V - scales 10 mV shunt drop to 1.0 V output for direct ADC interfacing |
| Offset Voltage (max) | ±60 µV - enables <0.06% error at 10 mV full-scale input |
| Gain Error (max) | ±0.5% - guaranteed over –40°C to +125°C, critical for BMS charge/discharge accuracy |
| Common-Mode Range | –0.3 V to 26 V - supports high-side sensing on 12 V/48 V/800 V auxiliary rails with local 3.3 V or 5 V supply |
| Supply Voltage | 2.7 V to 26 V - allows single-supply operation from MCU I/O rail or isolated DC/DC output |
| Quiescent Current | 100 µA max - minimizes self-heating and enables always-on current monitoring in sleep modes |
| CMRR | 95 dB min - suppresses noise from high-dv/dt motor drive or DC/DC switching nodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision current sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| INA240A1QDRQ1 | 100 V/V gain, ±10 µV offset (typ), 2.7–5.5 V supply only, 400 kHz bandwidth | Requires external level-shifting for >5.5 V common-mode; better for low-voltage, high-bandwidth motor control | Select when higher bandwidth and lower offset are needed, and supply is limited to 5.5 V |
| MAX40056ATA+T | 100 V/V gain, ±50 µV offset (max), 2.7–5.5 V supply, 200 kHz bandwidth, integrated overvoltage protection | Limited to 5.5 V supply; includes internal clamps but no 26 V common-mode tolerance | Select when robustness against transient overvoltage is prioritized over wide common-mode range |
Compared with INA240A1QDRQ1 and MAX40056ATA+T, the ZXCT214QCDW-7 uniquely supports 26 V common-mode and 26 V supply in a single package - making it the only choice for direct high-side sensing on 12 V/24 V/48 V automotive rails without external level shifters or regulators.

FAQ
What is the maximum common-mode voltage the ZXCT214QCDW-7 can tolerate?
The ZXCT214QCDW-7 supports a common-mode input voltage range from –0.3 V to 26 V, verified per DS45518 Rev. 4–2 Absolute Maximum Ratings and Recommended Operating Conditions. This allows direct high-side sensing on 12 V, 24 V, and 48 V automotive rails without external level-shifting circuitry, provided the supply voltage (V+) is ≥2.7 V and ≤26 V.
Does the ZXCT214QCDW-7 require external resistors for gain setting?
No. The ZXCT214QCDW-7 has a factory-trimmed fixed gain of 100 V/V; no external gain-setting resistors are required. Its internal resistor network is laser-trimmed during post-package calibration to achieve ±0.5% max gain error over temperature, eliminating layout sensitivity and matching errors associated with external components.
Can the ZXCT214QCDW-7 be used for bidirectional current sensing?
Yes. By applying a stable bias voltage (e.g., V+/2) to the REF pin, the output swings symmetrically around that reference to indicate direction - enabling bidirectional measurement in battery charge/discharge monitoring. The device's rail-to-rail output and low offset (±60 µV) ensure accurate zero-current detection and polarity resolution down to sub-mA levels.
What is the thermal resistance and maximum junction temperature rating?
The ZXCT214QCDW-7 in SOT363 has RθJA = 228 °C/W and RθJC = 64 °C/W per JEDEC 51-7 test board. Its maximum operating junction temperature is +150 °C, with guaranteed operation from –40 °C to +125 °C ambient - validated under AEC-Q100 Grade 1 stress testing including 1000-hour HTOL at +125 °C.
