PMIC – Gate Drivers, also known as power management integrated circuits, are a type of integrated circuit (ICs) that perform various power management tasks, including helping to drive, control, and optimize the performance of other devices such as processors, memory, and other peripherals. The UC2707DW is a power management IC from Texas Instruments and is designed for a range of applications including motor control, circuits for home appliances, switching power supplies and power factor correction, industrial automation, and automotive applications. In this article, we will discuss the UC2707DW application field and its working principle.

The UC2707DW is a versatile, high speed MOSFET gate driver IC, specifically designed to simplify the task of driving high power and current in applications up to 5 A. This IC can be used to drive various MOSFETs, insulated gate bipolar transistors (IGBTs), and SCRs, with the help of an optimized frequency response. The UC2707DW offers excellent current regulation, protection features, such as output short protection and programmable pre-driver protection. It is also RoHS compliant and available in SOIC 14 and SOP 14 packages.

The UC2707DW has a built-in dual switching regulator, which can be used to generate a pre-driver voltage of -2 V, allowing fast switching times and thus leading to better efficiency. The IC also includes two programmable thresholds, allowing users to fine tune the pre-driver voltage and power-up reset threshold. Furthermore, the IC has an embedded high-speed error amplifier and 3A DC-DC converter for improved power delivery. The power delivery module can be used to supply power to downstream devices, and includes programmable current limit and burst mode operation.

The UC2707DW also features built-in overvoltage, overcurrent and undervoltage protection, as well as programmable overcurrent, undervoltage and overvoltage detection levels. It also includes a pre-driver comparator, which can be used to set a pre-driver hysteresis level. Additionally, the IC offers an external fault signal, which can be used to shut down the pre-driver in case of an external fault.

The UC2707DW also incorporates a sensitive gate driver, which enables fast switching and improved efficiency. The gate driver is designed to start switching immediately after the pre-driver has enabled the gate driver latch. This helps to reduce the overall switching time by providing faster turn-off of the switching device, leading to better efficiency. Additionally, the UC2707DW has a built-in undervoltage lockout (UVLO) comparator and programmable UVLO threshold.

The UC2707DW is a high-performance MOSFET driver from TI, designed to deliver high-speed switching and optimized power delivery in various applications. It enables fast switching of various voltage-source devices, and offers various protection features, such as programmable pre-driver protection and output short protection. The IC also features a sensitive gate driver and built-in dual switching regulators. It is RoHS compliant and available in SOIC 14 and SOP 14 packages.
