Introduction

UCC27201ADDA is an integrated gate driver designed and manufactured by Texas Instruments. It is part of TI’s family of Gate Drivers, which are integrated circuits and components specifically designed to drive power switches, such as toggle and low-side switches, as well as many other power devices. The UCC27201ADDA is a high-side, low-side, and neutral-side driver that features a wide operating voltage range from 8 to 30 volts, and a maximum output current of up to 120mA per channel. The UCC27201ADDA also features built-in thermal shutdown, over-current and under-voltage protection.

Application Field

The UCC27201ADDA is well suited for motor drive applications because of its wide operating voltage range, maximum output current and integrated protection features. It can be used in industrial, automotive and aerospace applications, such as stepper motors, brushless DC motors, fans, pumps, and actuators. Additionally, the UCC27201ADDA is useful in medical applications, such as ventilators, respirators and oxygen concentrators.The UCC27201ADDA is also suitable for high-power applications, due to its high current and wide operating voltage range. It can be used in home applications, such as air conditioning and heating systems, as well as in renewable energy generation systems, such as solar and wind turbines.

Working Principle

The UCC27201ADDA is a current control circuit, meaning that it takes the current from the power device and then amplifies and converts it into a signal suitable for driving a desired output. It works by driving a voltage from its input signal through a series of transistors, which determine the level of current output. This signal is then amplified and converted into a suitable output for driving a desired power device.The main components of the UCC27201ADDA include power switches, transistors, an enable control logic circuit, an under-voltage lockout (UVLO) circuit and an over-current protection circuit. The enable control logic circuit is used to control the power switches. When the enable signal is present, the power switches are turned on and the current output is amplified.The over-current protection circuit is used to protect against any excessive current flow through an output port. It works by comparing the generated or anticipated current with a predefined limit. If the current is above the predefined limit, the circuit will shut down and stop the flow of current to the output port. The under-voltage lockout (UVLO) circuit is used to protect the UCC27201ADDA from accidental damage due to a low supply voltage.

Conclusion

The UCC27201ADDA is an integrated gate driver designed and manufactured by Texas Instruments for use in motor drive applications, as well as high-power and medical applications. It features a wide operating voltage range from 8 to 30 volts, and a maximum output current of up to 120mA per channel. The UCC27201ADDA has built-in over-current and under-voltage protection and works by driving a voltage from its input signal through a series of transistors.
