SEC1210-CN-02

The SEC1210-CN-02 from Supertex Inc. is a bi-directional thyristor driver designed for applications where high dv/dt and di/dt are required such as AC motor drives, motor speed controllers, motor throttle controllers, and delta regulation. This product has a built-in level shifter and can supply a drive current up to 250mA. It also includes a 2-kHz oscillator which is used to generate a synchronized square wave output.

The SEC1210-CN-02 contains two channels and is capable of supplying a continuous output current of 250mA and a peak output current of up to 450mA, each with a rise and fall time of less than 15µs. The device is powered by a 5V input voltage and is packaged in an 8-pin SOIC. The chip is also capable of driving an N-channel MOSFET or IGBT and it has a built-in logic level shifter for switching between logic low and logic high levels.

Application Fields

The SEC1210-CN-02 is designed for use in applications such as AC motor drives, motor speed controllers, motor throttle controllers, and delta regulation with high load current requirements. It is also used in motion control systems, such as robotic arms, manufacturing, and medical applications. In addition, the SEC1210-CN-02 can be used in industrial, appliance, automotive, and power conversion applications.

Working Principle

The SEC1210-CN-02 is a simple, two channel bi-directional MOSFET/IGBT driver. The device is powered by a 5V input voltage and contains a 2 kHz oscillator that produces synchronized square wave output. The chip is also equipped with a logic level shifter that allows it to switch between logic low and logic high levels. The device is capable of supplying a continuous output current of 250mA and a peak output current of up to 450mA, each with a rise and fall time of less than 15µs.

On the input side of the device, an input voltage is applied to either of the two channels. This voltage is then amplified and inverted before being applied to the gate of the attached MOSFET/IGBT. As the voltage rises, the MOSFET/IGBT is turned on. When the input voltage is reduced, the MOSFET/IGBT is turned off and the current is switched off. The device also includes a logic level shifter, which allows the SEC1210-CN-02 to switch between logic low and logic high levels, enabling precise control of the output current.

The SEC1210-CN-02 also features an On/Off pin, which is used to enable or disable the device. When the On/Off pin is activated, the device is disabled and the output current will no longer be controlled. This is particularly useful for applications that require an override feature, such as motor controllers or motion control systems.

Conclusion

The SEC1210-CN-02 from Supertex Inc. is a bi-directional thyristor driver designed for applications where high dv/dt and di/dt are required. The device is capable of supplying a continuous output current of 250mA and a peak output current of up to 450mA. It also includes a logic level shifter, which allows the device to switch between logic low and logic high levels. The SEC1210-CN-02 is typically used in applications such as AC motor drives, motor speed controllers, motor throttle controllers, and delta regulation.
