The VLA513-01R is a general-purpose gate driver which reinforces PMIC (Power Management IC) and is a miniaturized package solution for use in increasing the operating speed and driving current of applications like automotive, industrial, cellular and consumer electronics. It is capable of providing a maximum peak output current of 8A to drive an N-channel MOSFET or IGBT and can be used in a wide number of applications.

The VLA513-01R\'s excellent controllability and robustness are resulted from its wide input voltage range and the use of constant-off-time high- and low-side drivers which appears to be the optimal choice carrying applications with high impedance. Additionally, several other features are offered like an adjustable switching frequency, a low jitter frequency, designed versus EMC (electro-magnetic compatibility), hysteretic current sensing, dependence of the input voltage on the operating temperature, and over-temperature protection.

The VLA513-01R features a self-biasing differential input mechanism that supports a wide range of supply voltages ranging from 4.5V to 25V among other features. The input voltage is used to regulate the control logic and the current sense amplifier. This also helps to reduce its circuit element count, which in turn improves its power efficiency and reduces the total system size. This arrangement also helps to reduce the overall operating temperature of the device.

The VLA513-01R features low output resistance and a wide duty cycle range to provide high immunity against inductive switching path influences and guaranteed hysteresis. The inductance in the system is reduced by the use of the built-in control logic, while robust switching characteristics and enhanced protection measures help to ensure a consistent, reliable and safe operation.

The VLA513-01R gate driver is the ideal choice for motor drives, power switching, and power converters, where it can be used to drive N-channel MOSFETs or IGBTs. It features a noise-filtering power ground that combines the power-supply connection and the ground connection to reduce output noise. The VLA513-01R also offers various protection features such as over-current protection, short-circuit protection, current-sensing threshold protection and over-temperature protection.

The VLA513-01R gate driver offers an adjustable switching frequency, which can be adjusted according to the circuit specifications and the application. It also provides an adjustable external gain control and a differential common-mode Bus configuration, helping to reduce power dissipation. Additionally, the device’s advanced CMOS process technology allows a very low quiescent current, making it ideal for low power applications.

In conclusion, the VLA513-01R gate driver is a highly efficient, cost effective and reliable gate driver which can be used in a wide range of applications from automotive, industrial, cellular and consumer electronics. It offers excellent controllability and robustness, wide input voltage range, adjustable switching frequency, low jitter frequency, and several protection features.
