The IR3519STRPBF is a compact gate driver that contains a high voltage power MOSFET switch, operating at up to 70V VDS (drain-to-source voltage) and 250A Id (drain current). This device is designed for enhanced reluctance, synchronous and DC motors, sensors and other electronic equipment used in industrial, commercial and residential applications. It is an ideal choice for industrial and commercial applications such as wind and wave power harvesting, automotive motors and other large industrial drives, as well as intelligent systems and sensors.The IR3519STRPBF is powered by an internal charge pump that provides up to 700V VCC (collector-to-source voltage) from an input voltage of 5V. This eliminates the need for an additional voltage regulator and simplifies the AC design considerably. The device also provides logic level thresholds and low on-resistance, making it compatible with many logic families.The high voltage and low current switching ability of the IR3519STRPBF make it suitable for a wide range of applications, including intelligent motor control, high efficiency power converters and power supplies, industrial automation and lighting, radio frequency (RF) amplifiers, and wireless power transfer.The internal charge pump of the IR3519STRPBF is powered from an external 5V DC source and provides up to 700V VCC with a frequency of up to 34kHz. This allows for high-speed, low side drives with low switching losses and excellent power efficiency. The device also features an active Miller clamp, which eliminates any shoot-through current at the outputs and improves device reliability.The IR3519STRPBF is a perfect solution for PFC (Power Factor Correction) applications, providing precise current control and excellent power efficiency. The device features a wide voltage range of up to 70V and a variety of fault protection features, such as overvoltage, undervoltage, overcurrent and overtemperature protection.The IR3519STRPBF works by opening and closing a mechanical switch, controlled by a logic level signal from an external control source. The device has a gate drive circuit which is used to control the opening and closing of the switch in response to the logic level signal. The switch is opened and closed by applying a voltage level on the gate of the switch and the device acts as a buffer between the control source and the switch.The IR3519STRPBF provides high voltage with enhanced reliability, making it ideal for industrial and commercial applications. The device can efficiently drive any MOSFET switch up to 70V and 250A, allowing for high power operation. The low on-resistance and logic level thresholds make the device compatible with many logic families. The active Miller clamping circuitry has also been added to the device for improved fault protection and improved device reliability.In conclusion, the IR3519STRPBF is a powerful high voltage gate driver used in industrial and commercial applications. The device is powered by an internal charge pump which provides up to 700V VCC from a 5V input. It features low on-resistance, active Miller clamping and a variety of fault protection features, making it perfect for large industrial drives, PFC applications and intelligent motor control.
