The UCC2813DTR-4 is a high voltage, low power MOSFET driver which operates using regulatable supply for on/off switching, providing up to 5.25V peak output voltage and 2.5A short-circuit current capability. It is designed to drive an external N-channel MOSFET with a gate threshold voltage as low as 3.0V, allowing for greater flexibility and higher switching speed than traditional BJT/IPM applications. This device is an ideal solution for applications such as AC/DC conversions, offline switchers, power supply systems and other high-performance power applications.
The UCC2813DTR-4 provides a wide range of features which enable the device to be used in a variety of applications, such as high efficiency power conversion, high power density design and high EMI compliance. Its regulatable supply voltage range is from 7V to 40V and its peak output voltage is 5.25V, providing greater design flexibility and allowing for a wider range of operating conditions. The device can also be used in a synchronous rectifier circuit, and has a dedicated bias pin to control the MOSFET turn-on time and lower losses. Furthermore, the device contains additional features such as an overcurrent/over-temperature protection and an undervoltage lockout protection, making it suitable for a variety of applications.
To further understand how the UCC2813DTR-4 works, it is important to consider the fundamentals of its applications and the main working principles. The device can be used in either an on-off or a pulse-width-modulation (PWM) control mode and the resulting performance of the system depends on the control pattern that is used. In on-off control mode, the external MOSFET transitions from the off-state to the on-state if the driver\'s input voltage is greater than the over-temperature threshold, and then as the regulated supply voltage increases, the device maintains the on-state until the input voltage reaches the overcurrent threshold. In PWM control mode, the external MOSFET transitions from the off-state to the on-state if the driver\'s input voltage is greater than the over-temperature threshold, and then as the regulator supply voltage increases, the device continuously maintains the on-state until the PWM frequency is changed or the input voltage reaches the overcurrent threshold.
In conclusion, the UCC2813DTR-4 is a high-performance power MOSFET driver which is suitable for use in high voltage, low power applications such as AC/DC conversions, offline switchers and power supply systems. The device provides a range of features which enable it to operate efficiently and reliably. Additionally, the device is equipped with a regulatable supply voltage range, a peak output voltage of 5.25V and a dedicated bias pin for controlling the MOSFET turn-on time, providing greater design flexibility and high-performance operation.
