Isolators - Gate DriversThe SI8273AB-IS1 is a high side driver intended for isolated gate drive, power pulse isolation, and high speed signal isolation. It is a dual chip that combines an Isolator and a Gate Driver to provide a level of integration beyond that of a standard isolated driver. The SI8273AB-IS1 is designed to provide an isolated drive for high power devices such as IGBTs, MOSFETs, and other power devices. It can provide an isolated low volt drive while isolating high voltages.Application FieldThe SI8273AB-IS1 is typically used in power conversion circuits, where the levels and signals on one side of an isolation barrier need to be driven to the other side, often at high voltages and frequencies. It is particularly useful for applications where the isolation barrier is relatively large, such as in motor drive systems, and for applications that require multiple channels of isolation, such as in power supplies.Working PrincipleThe SI8273AB-IS1 is composed of two chips: an Isolator and a Gate Driver. The Isolator isolates a signal up to 500Vrms, while the Gate Driver is capable of driving high power devices up to 15A. The Isolator isolates low voltage digital signals, and the Gate Driver activates the power devices on the high side of the isolation barrier.The Isolator works by utilizing the electromagnetic principle of mutual-inductance. The Isolator consists of an input coil (primary side) and an output coil (secondary side). When a low-voltage signal is applied to the input coil, a high-voltage magnetic signal is created, which is coupled through the isolation barrier and conducts through the output coil. This voltage is then amplified and fed to the Gate Driver, which then controls the power devices.The Gate Driver uses pulse-width modulation (PWM) technology to allow switch devices to be controlled with a low-voltage signal. It works by rapidly switching the high voltage power supply off and on via the power device. The PWM system allows precise control of the power device by changing the duty cycle of the PWM.The SI8273AB-IS1 offers a versatile range of features that make it ideal for many applications. It is capable of operating at up to 500Vrms and frequencies of up to 10MHz, and it offers a wide range of operating temperatures. The combination of an Isolator and Gate Driver also offers increased integration and system reliability.The SI8273AB-IS1 is an ideal solution for applications that require isolated gate drive, power pulse isolation, and high speed signal isolation. Its combination of an Isolator and Gate Driver allows for easy integration, improved system reliability, and versatile operating conditions. It is an ideal solution for motor drive systems, power supplies, and other applications where an isolated signal is required.
