UCC27323P

The UCC27323P is a high-side supply voltage gate driver. It provides an industry leading surge-handling capability, allowing the device to sustain performance under harsh automotive conditions. This feature is especially beneficial for applications where high-current loads can create transients. The integrated smart protection features protect the device against over-voltage, under-voltage, and over-current conditions.

The UCC27323P features two built-in power MOSFETs, with one high side and one low side switch, that can drive a wide range of external loads. It also features a 2-phase clock input, which can be used to generate different switching patterns for precise control of the devices. The device can be operated in either voltage- or current-loop control mode, providing extremely precise control over the load. In addition, the die has built-in temperature and fault diagnostics, which can help improve system reliability.

The UCC27323P is suitable for a wide range of automotive applications, such as fuel pumps, actuators, and door locks. It is also used in industrial and commercial applications, including servo motors, pumps, and compressors. The device offers exceptional flexibility, allowing for the adjustment of switching duty cycle, over-temperature protection, and over-current protection.

In terms of working principle, the UCC27323P is a dual-output voltage gate driver. It works by detecting the input voltage of the load and adjusting the output gate voltage accordingly. The device uses a current-sensing technique to detect the actual voltage level of the load. This technique needs to be calibrated according to the actual application, to ensure precise control of the output. The output gate voltage is determined by the input voltage, and is adjustable with an external resistor. This allows the device to be tuned to provide the best performance for a given application.

The UCC27323P uses a dual-output architecture to achieve the highest possible output power. The dual outputs provide efficient, phase-correct current driving to reduce power losses caused by reflection on the load. The outputs are designed to ensure that the voltage across them is always low enough to protect the device from damage. The device also has built-in over-voltage and over-current protection that helps to protect the device from thermal runaway and overload conditions.

The UCC27323P is a versatile gate driver device that is suitable for a variety of automotive and industrial applications. It features an industry-leading surge-handling capability, integrated smart protection features, a dual-output architecture, and adjustable gate voltage. This makes the device an excellent choice for applications that require precise voltage control and protection from thermal overload conditions.
