The NCV4276DS25R4 is a low-side (sink) gate driver with a built-in power supply regulator suitable for driving high-current and high-voltage loads. This integrated circuit is mainly used in automotive applications and is ideal for battery management systems and DC motors.Low-side gate driver ICs are circuit components that are usually utilized in buck or buck-boost power factor converters to efficiently switch low-voltage loads, such as MOSFETs and BJTs. This type of driver is designed to drive the load in one direction – either in the buck (pull-up) or buck-boost (pull-down) mode.The NCV4276DS25R4 includes a built-in power supply regulator, meaning it can be used in complicated switching power supply designs without the need for a separate power supply voltage regulator. This feature provides much greater design freedom and helps to reduce the overall system cost. Additionally, the driver incorporates a unique bootstrap circuit to enable the maximum switch current of 20A for heavy-duty applications.The NCV4276DS25R4 is programmable over the entire supply rail range, making it an optimal solution for magnitude and speed control of four pulse-width-modulated (PWM) motor drives. It can also be used in applications such as automotive ignition coils and infotainment systems, as well as other low-side driver applications.The drive operates over an extended power supply range from 7V to 18V and features a low on-resistance of 55mΩ typical. This makes it well-suited for automotive power systems with battery voltages of up to 17V. The driver also features a wide temperature range of -40°C to 150°C, making it suitable for automotive and industrial applications.To ensure proper drive functioning, the NCV4276DS25R4 incorporates various advanced safety features. It includes a built-in overtemperature protection, ESD protection, overvoltage protection, and undervoltage protection. It also has an adjustable current limit to protect the system from overloads and shorts.In summary, the NCV4276DS25R4 is a low-side gate driver with an integrated power supply regulator. Its versatile feature set and low on-resistance make it suitable for a variety of automotive and industrial applications. Additionally, its safety features ensure proper drive function and reliability.
