JTAC20xM CMOS Zero-crossing Detection Chip

PublishTime：2023-08-14

●Description
■JTAC20xM is a thyristor driver with zero-crossing detection function built-in. Several protection features are embedded to ensure reliable and safe system operations: over-temperature shut-down, over-voltage clamping. The device is powered from VDD pin. As soon as the change in the polarity of the VAC line voltage (i.e. zero point) appeared at ZCD pin is detected, the external thyristor can be triggered almost instantly. Eliminating the dead angle of thyristor in the traditional drive circuit and reducing the influence of EMI on the power supply. In practice, the device allows any MCU implemented in low-voltage CMOS process to operate a thyristor which typically cannot be triggered properly by CMOS-level control signal. After the chip detects the zero-crossing signal (Mode 1 and Mode 3), the GATE will automatically pull up to the VDD value if EN is not enabled, then improving the anti-interference ability of the thyristor.
