The TC9402CPD is an IC that provides power management of voltage and frequency (V/F) conversion as well as frequency-to-voltage (F/V) conversion. It is ideal for use in areas such as automotive, industrial, home appliances and portable applications. The device is designed with a low power consumption level, making it suitable for battery-operated systems. The device can operate on a supply voltage range of 0.9V to 5.5V, and has a total output of up to 24V.

Function

The TC9402CPD is designed for applications that require both V/F and F/V conversion. It can provide V/F conversion up to 24 Volts from any input voltage range of 0.9V to 5.5V. It also provides F/V conversion up to 4V from input frequencies of up to 25MHz. The device can operate in three different modes: pulse-width modulation (PWM), speed control and voltage control. The device is also capable of providing adjustable frequency control by allowing the user to select the exact frequency required.

Applications

The TC9402CPD is suited for applications in automotive, industrial, home appliances and portable applications. It is ideal for use in electric motor control applications, such as motor speed control, fan speed control, and power conversion from AC to DC. It is also suitable for portable energy management applications such as charging and discharging battery modules. Finally, the device is used in medical applications such as medical pump control and medical instrumentation.

Working Principle

The TC9402CPD works by converting voltage input signals into frequency output signals. It first senses the voltage level and uses the internal comparators to divide it into three parts, based on the operating mode. The output of this part is then filtered by an internal filter and converted into a frequency. This frequency is then output to the external device.

The same process is used for F/V conversion as well. The device starts by sensing the input frequency and using the internal comparators to divide it into two parts. The output of this part is then filtered by an internal filter and converted into a voltage. This voltage is then output to the external device.

Conclusion

The TC9402CPD is an IC that has been designed for V/F and F/V conversions. It is designed for applications such as motor control, power conversion, portable energy management and medical instrumentation. The device can operate with a supply voltage range of 0.9V to 5.5V, and has a total output of up to 24V. The device works by sensing the voltage or frequency level, dividing it into parts and converting it into a frequency or voltage signal. This makes it suitable for a wide range of applications.
