PMIC stands for Power Management Integrated Circuit - Gate Drivers. The UCC27201DR is a high-performance, low- on-resistance, high-speed gate driver with leading-edge features. It is designed for use in power management applications requiring high performance and functional integration. This article will discuss the application field and working principle of the UCC27201DR.
The UCC27201DR is a dual-channel, high-efficiency gate driver optimized for both single- and multi-phase synchronous Buck regulators. With a characteristic supply current of only 200 μA typical, high frequency performance in the kilohertz range and a low 480mV typical supply voltage, the device provides high-performance power delivery. The UCC27201DR offers an integrated slew rate control loop that improves transient performance. In addition, the device can operate over supply voltages of 4.5V to 16V, allowing the user to reduce component size, board space, and cost. The high-current operating margin of 1.5A simplifies design requirements and ensures improved efficiency within wide temperature ranges.In addition, the UCC27201DR features built-in protection features. The device includes a power-on reset and an over-current/over-temperature protection feature. This feature reduces stress on the power stage components and helps protect the system from damage due to long-term current or thermal excursions.The UCC27201DR has two independent logic-controlled inputs, each of which can be configured as either a positive or negative logic signal. The signal level at each of the inputs is monitored and can be used to control the turn-on speed of the output, with fast, medium, and slow slew rates available.In addition, the UCC27201DR features a low-voltage power-on reset, as well as a programmable over current/over temperature protection feature. The device integrates two logic-controlled inputs and five integrated protected power FETs, two NFETs and three PFETs, eliminating the need for discrete components in the power stage design.The working principle of the UCC27201DR is that it takes in a logic control signal and, based on the state of the input signals, drives the P-channel and N-channel FETs to switch on and off. Depending on the input signal, the output switch can be configured to operate in slow rise, fast rise and brake modes. The device operates on a wide supply voltage of 4.5V to 16V, allowing the device to reduce component size, board space and cost. The device has built-in protection features, including power-on reset, overcurrent/over-temperature protection, undervoltage lockout and overtemperature protection, to provide peace of mind for system designers.
The UCC27201DR can be used in a variety of power management applications, from standard synchronous converters, such as step-down (Buck) and step-up (Boost) converters, to motor control systems. The device is ideal for use in automotive, industrial, and consumer applications where power delivery needs to be precise and efficient. The UCC27201DR is also backed by an extensive list of safety certifications, such as ISO26262, functional safety, and AEC-Q100, providing designers with the assurance that their devices will operate reliably and safely in rugged automotive environments.In summary, the UCC27201DR is a high-performance, low- on-resistance, high-speed gate driver with leading-edge features. It is optimized for single- and multi-phase synchronous Buck regulators and offers an integrated slew rate control loop that improves transient performance. With a wide 4.5V to 16V supply voltage, the device eliminates the need for discrete components in the power stage design and provides enhanced protection features with respect to current and temperature. This makes the UCC27201DR a valuable addition to the rapidly expanding market for power management integrated circuits.
