MT9522 chip is a new generation current detection chip launched by MagnTek, which is a fully integrated isolated linear current sensor chip based on Hall effect.
| Packaging form
| Product introduction
MT9522 series is a new generation current sensor chip launched by MagnTek after MT9222 series. The "current magnetic" conversion module is integrated in the chip, and the magnetic field is converted into a voltage output signal proportional to the input current using the Hall effect principle. It also has 4800Vrms dielectric strength, "zero" hysteresis, over-current alarm function and 2.2us response time, which are very suitable for various string photovoltaic inverter, vehicle charger and other current detection applications, meeting AEC-Q100 requirements.
| Application circuit
1. Customers can choose: 3.3V and 5V power supply versions
2. Customers can choose two output modes: fixed output mode and proportional output mode
Any combination of the above two
