UCC27200ADDAR Application Field and Working PrinciplePMIC gate drivers are integrated circuits used in the design and manufacture of power electronics systems. They are used to control the flow of electric current between power components. UCC27200ADDAR is a PMIC gate driver that is used to provide low-side switch protection and also supports high current output with fast switching capabilities.The UCC27200ADDAR is a high-performance, low-cost Low-Side Drive IC designed to reduce the cost and complexity of your design by providing integrated current sensing, low EMI switching, and low power consumption. It is a single-channel high-side and low-side switch for use in switching power supplies and lighting applications. This IC does not require an external high-side driver and provides tight timing control and dual-level high current output.In terms of its application areas, the UCC27200ADDAR is a reliable solution for switching power supplies and lighting applications. It can be used as a low-side drive circuit for either AC or DC outlets; as well as for lighting enable/disable, dimmer, and color control. The adjustable current sensing feature makes it suitable for both pulsed and continuous operations and it is capable of operating over a wide range of temperature environments.To understand its working principle, it is important to first address its overall structure. The UCC27200ADDAR is composed of two main subcircuits. These are the low-side driver circuit and the high-side driver circuit. The low-side driver circuit is comprised of an on-board high-voltage FET and an adjustable current sense circuit. This low-side driver circuit is designed to provide low-side switch protection with a maximum switching current of 30A. The high-side driver circuit is composed of a P-channel MOSFET and a current-sense circuitry that is used to control and monitor the current flowing through the MOSFET. The current sense circuitry consists of a reference voltage divider and a sense resistor that is used to measure the current flowing through the MOSFET. The current sense and control signals are fed to the on-board microcontroller for generating the “on” and “off” signals, as well as for monitoring the current.The UCC27200ADDAR is capable of providing dual-level current output with a fast switching speed of 1.3 microseconds per A. This is achieved with an external high-side drive circuit that drives exclusively low-voltage MOSFETS. The fast switching speed, coupled with the adjustable current sense circuitry ensures that the switch can handle high current output with tight control.Overall, the UCC27200ADDAR is a cost-effective and reliable solution for switching power supplies, lighting applications, and high current output applications. It is equipped with both a high-side and low-side driver circuit, making it suitable for both AC and DC outlets. Furthermore, it is capable of providing dual-level current output with a fast switching speed of 1.3 microseconds per A, making it an effective solution for high current output applications.
