2EDN8523RXUMA1

2EDN8523RXUMA1 is a integrated gate driver from NXP semiconductors, which belongs to the Power Management ICs (PMICs) family. Specifically, the 2EDN8523RXUMA1 is a half-bridge gate driver which integrates two high side and low side half-bridge gate driver channels, suitable for DC and AC application.The typical application of the 2EDN8523RXUMA in the industrial and automotive sector could include motor drivers, motor control, power conversion and motor speed control. The product’s input switching edges and rail-to-rail output are used to enhance the product reliability. The 2EDN8523RXUMA1 is well-suited for driving Si, SiC, and GaN power devices. The 2EDN8523RXUMA1 provides a wide range of benefits, such as over-voltage protection and over-temperature protection, reducing the complexity of the control system and design cycle, thus leading to cost savings from component integration, board layout, and system testing. Moreover, its low operation current, high switching frequency, high slew rate, and good linearity further contribute to the product’s advantages. The 2EDN8523RXUMA1 gate driver minimizes the time delay between high side and low side drivers, ensuring the high output voltage of the power switch.In terms of the product’s working principles, the 2EDN8523RXUMA1’s gate driver consists of two channels, a high side channel and a low side channel. Each channel is capable of driving a high side and low side power switch, through which it provides a half bridge which is able to deliver power to a motor or any other application.The half-bridge outputs of 2EDN8523RXUMA1 are driven independently and serve both AC and DC applications. High-side and low-side drivers are driven by a differential logic signal. When an input logic transition occurs, an output current pulse is generated. The pulse generated on the two outputs ensures that the switching statuses of the power switches in the bridge remain consistent.When an external signal is given, this signal is initially amplified by two pre-drivers and sent to both half-bridge outputs. The pre-drivers work in the negative rail to increase the signal level. The signal at the output is then isolated from the signal at the input, and the signal is transferred to the PWM latch voltage detector.The PWM latch voltage detector is composed of a PWM latch and a voltage detector. The PWM latch works in the negative rail and provides noise immunity and transient suppression, while the voltage detector monitors the voltage of the PWM signal to detect any signal changes. The output of the PWM latch voltage detector drives the gate driver and the switch level converter. The switch level converter converts the logic level signals to drive the gate driver and converts the output level signals to drive the output bridge stage. In conclusion, the 2EDN8523RXUMA1 gate driver is a feature-rich and cost-effective solution for a wide range of industrial and automotive applications. Its wide range of benefits including over-voltage protection, over-temperature protection, and improved efficiency, makes it an ideal choice for many designs. The half-bridge outputs are driven independently and serve both AC and DC applications, providing maximum system flexibility.
