MCx1101 current sensor ICs
Isolated AMR current sensor ICs from +/-5 A to +/-65 A in SOIC-16, with 4.8 kV dielectric strength.
- +/-5 A to +/-65 A
- 4.8 kV isolation
- 3.3 V or 5 V
- SOIC-16
Overview
The MCx1101 family are fully integrated, bi-directional analog output current sensor ICs based on Aceinna's anisotropic magneto-resistive (AMR) technology. A low resistance copper conductor inside the SOIC-16 package gives an isolated current path for high-side or low-side sensing of AC or DC current. Parts come in fixed gain (MCA) and ratiometric (MCR) output versions for 3.3 V or 5 V supplies.
Built for
- Server, telecom and industrial power supplies
- PFC and inverter control
- Motor control and servo drives
- Solar inverters, UPS and battery charging
Key features
AMR sensing
Low noise and good linearity, with a structure designed to reject stray and common mode fields.
High bandwidth
Wide bandwidth and low phase delay suit current feedback loops with fast SiC and GaN stages.
Isolated current path
4.8 kV dielectric strength, certified to UL/IEC/EN62368-1.
Overcurrent detection
FAULTB open drain output with the threshold set by the VOC pin.
Low primary resistance
0.9 mΩ integrated conductor keeps power loss low.
Factory calibrated
Low offset error and an output proportional to current, with a Vref pin on fixed gain parts.
