Product details
Overview
MCQ1823GQTE-510BRNAEC-Z from Monolithic Power Systems is an automotive-grade, linear Hall-effect current sensor IC with integrated over-current detection (OCD), designed for bidirectional DC/AC current sensing up to ±10A. It features a 0.6mΩ internal conductor, 200mV/A sensitivity at 5V supply, ±2.5% total output error, and 120kHz bandwidth. Its differential Hall array rejects external magnetic field interference, enabling accurate measurement in noisy motor control or power supply environments.
For engineers reviewing the MCQ1823GQTE-510BRNAEC-Z datasheet, MCQ1823GQTE-510BRNAEC-Z pinout, MCQ1823GQTE-510BRNAEC-Z application, or MCQ1823GQTE-510BRNAEC-Z equivalent, this device delivers AEC-Q100 Grade 1 qualification, fast 1µs OCD response, ratiometric or absolute VOUT options, and TQFN-12 (3mm×3mm) packaging for space-constrained automotive and industrial current monitoring.
Technical Context
The MCQ1823GQTE-510BRNAEC-Z employs a differential Hall transducer pair with spinning current offset cancellation to achieve stable zero-current output (±15mV over temperature) and immunity to homogeneous and gradient stray fields. Its primary conductor is integrated into the package with fused IP+ and IP− terminals, enabling galvanic isolation and high-current capability without external shunts.
It operates from a 4.5–5.5V supply, delivers analog VOUT proportional to sensed current, and provides an open-drain /OCD output with user-configurable threshold (via external pull-up resistor) and 1µs propagation delay. The device supports both ratiometric and absolute output modes, factory-trimmed for accuracy across -40°C to +125°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5V to 5.5V - Ensures robust operation across automotive battery variations including cold-crank conditions. |
| Rated Current Range | ±10A bidirectional - Supports precise sensing of forward/reverse motor phase currents or bidirectional DC bus flow. |
| Sensitivity | 200mV/A at TJ = 25°C - Delivers 2V full-scale output for ±10A range, enabling direct ADC interfacing without gain stages. |
| Total Output Error | ±2.5% over -40°C to +125°C - Guarantees calibrated accuracy across full automotive temperature range without system-level recalibration. |
| OCD Response Time | 1µs - Enables real-time fault shutdown in high-speed inverters or SMPS before destructive energy accumulates. |
| Bandwidth | 120kHz - Captures fast transient currents in PWM-driven motors or switching converters without phase lag. |
| Conductor Resistance | 0.6mΩ - Minimizes power loss (<60mW at 10A) and thermal rise in high-current paths. |
Pinout & Package
TQFN-12 (3mm × 3mm, 0.5mm pitch) package with wettable flanks, MSL Level 1, AEC-Q100 qualified. Exposed thermal pad enhances power dissipation in compact layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 IP+ | Primary current input (+) | Fused high-current terminal; connects to positive side of load or bus-carries full sensed current with minimal voltage drop. |
| 3, 4 IP− | Primary current return (−) | Fused return path; completes current loop through integrated conductor-enables isolated sensing without shunt resistor. |
| 5 GND | Signal ground reference | Low-impedance return for analog output and internal circuitry-must be connected to clean system ground plane. |
| 6 /OCD | Open-drain over-current flag | Asserts low within 1µs when IP exceeds ±10A; requires external pull-up (10kΩ–500kΩ) to set custom OCD threshold. |
| 7–10 NC | No connect | Internally unconnected pins-must remain floating or grounded per layout best practices; no routing required. |
| 11 VOUT | Analog current-proportional output | 0.5V to 4.5V ratiometric output (at 5V supply); directly interfaces with 12-bit+ SAR or delta-sigma ADCs. |
| 12 VCC | Power supply input | 5V nominal input; requires 0.1µF–1µF ceramic bypass capacitor to GND placed adjacent to pin for noise suppression. |
Key Features

FAQ
What is the maximum continuous current the MCQ1823GQTE-510BRNAEC-Z can measure?
The device is rated for ±10A bidirectional continuous current. Its 0.6mΩ internal conductor sustains this current with <60mW power dissipation at 25°C ambient. Derating is required above +85°C ambient per thermal limits in the datasheet, and peak transient currents beyond ±10A must be evaluated against OCD response time and thermal mass.
How is the over-current detection threshold configured?
The /OCD pin is open-drain and requires an external pull-up resistor (10kΩ–500kΩ) to VCC. Threshold is set between 50% and 240% of IPMAX (±10A) by selecting RPULLUP per the datasheet curve. For MCQ1823GQTE-510BRNAEC-Z, default threshold is ±10A (100% IPMAX) with RPULLUP = 100kΩ, yielding ~0.3V low-level output within 1µs.
Does the MCQ1823GQTE-510BRNAEC-Z require external calibration?
No. It is factory-trimmed for sensitivity, offset, and linearity, achieving ±2.5% total output error over -40°C to +125°C without end-of-line calibration. Zero-current output is 2.5V (ratiometric mode, 5V supply), and sensitivity is 200mV/A-both guaranteed across temperature and lifetime per datasheet specifications.
Can the MCQ1823GQTE-510BRNAEC-Z be used with a 3.3V supply?
No. The "5" in the part number indicates 5V supply option. MCQ1823GQTE-510BRNAEC-Z is specified only for 4.5–5.5V operation. For 3.3V systems, select the MCQ1823GQTE-310BRNAEC variant, which has identical ±10A range but 132mV/A sensitivity and 3.0–3.6V supply range.
What isolation rating does the MCQ1823GQTE-510BRNAEC-Z provide?
It provides basic isolation per IEC 62368-1 with a maximum working voltage (VIOWM) of 100V PK or DC. This is sufficient for low-voltage automotive (12V/48V) and industrial auxiliary power rails but not for mains-referenced 230V AC applications. Creepage and clearance meet reinforced insulation requirements for functional isolation in AEC-Q100 systems.
Is the TQFN-12 package compatible with standard reflow profiles?
Yes. The MCQ1823GQTE-510BRNAEC-Z uses MSL Level 1 moisture sensitivity and is qualified for JEDEC J-STD-020D-compliant reflow, including peak temperatures up to 260°C. The exposed thermal pad improves solder joint reliability and thermal performance-recommended stencil aperture is 70% open area with 0.15mm thickness.
How does the differential Hall architecture improve accuracy?
By placing two Hall elements at precise spatial offsets along the current path, the device measures magnetic field *difference*, canceling common-mode interference from external magnets or nearby conductors. This eliminates the need for magnetic shielding and enables ±0.5% nonlinearity and <15mV offset drift over temperature-key for closed-loop motor control stability.
