PMIC (Power Management Integrated Circuit) gate drivers are important devices, responsible for block-level power control into the digital system, enabling reliable and robust operation of a full-fledged system. UCC27223PWP is a digital gate driver product developed by Texas Instruments, which combines enhanced fast-switching performance and diagnostics into a single device. In this article, we will discuss the application field and working principle of the UCC27223PWP. UCC27223PWP device provides fast high-side and low-side outputs, allowing the implementation of low conduction and switching loss to reduce the system high temperature and power dissipation. It is ideal for automotive and industrial applications requiring wide operating temperature, such as motor speed and torque control and HVAC control. In addition, the integrated diagnostics enable pre-fault and fault-tolerant operation. The pre-fault feature allows for "watchdog" or "lock-out" operation, allowing the gate driver to comply with automotive requirements for preventing injection faults from occurring. In addition, the UCC27223PWP devices feature an integrated hyper-speed comparator, which allows them to provide faster switching performance compared to traditional gate drivers. With a combination of fast switching speed and extremely low on-chip power losses, UCC27223PWP devices can enable the efficient control of inductive loads in digital applications, such as high-power motor drives, battery charging systems and switch-mode power supplies (SMPS). The UCC27223PWP device is designed to provide improved protection against hazardous operating environments. The device can withstand a 40V to 95V range of supply voltages (without a bootstrap diode) and is capable of operating under extreme temperatures (down to -40°C). In addition, it features an integrated "diode emulation" technology, which reduces the stress on the external power-supply components by allowing the device to operate with a wide range of supply voltages.The UCC27223PWP device integrates several functions, such as over-current protection, over-voltage protection and soft-start, in order to provide improved device security. The integrated over-current protection feature protects the device from overloads and ensures that no power-induced damage occurs. The integrated over-voltage protection prevents device failure due to transient voltage spikes. The soft-start feature gradually ramps up the gate voltage, thus avoiding large inrush current and preventing system-level damage due to coil-dump currents. The UCC27223PWP devices feature a programmable slew-rate control, which allow the device to switch the load quickly and efficiently, while maintaining low power consumption. The device can be programmed to control slew rate from 0V/µs to 600V/µs. This feature eliminates the risk of exceeding the load current rating by allowing the device to switch the load\'s voltage accordingly, which minimizes the system power consumption.The integrated diagnostics feature allows the device to provide a user-selectable, continuous or one-shot monitor output to detect current, voltage and temperature faults. In order to ensure proper operation of the device in the event of a fault, the integrated EEPROM-reprogrammable memories allow the user to customize the diagnostic threshold levels, enabling fault recovery and fault management.The UCC27223PWP device is a monolithic integrated high-side, low-side gate driver which provides enhanced fast-switching performance, low on-chip power losses, integrated diagnostics and improved protection against hazardous operating environments. This device provides an ideal solution for applications that require fast switching speed and wide operating temperature range. It features integrated over-current and over-voltage protection and an integrated EEPROM-reprogrammable memory, allowing for pre-fault and fault-tolerant operation. Furthermore, the programmable slew-rate control feature enables efficient power management, reducing power consumption and system costs.
