The IXDE509SIA is an integrated gate driver integrated circuit that is designed to drive the gates of high- and medium- power MOSFETs or IGBTs. It offers 5 A peak current high-side and 5 A peak current low-side outputs. Its reverse-blocking capability (reverse operation protection) and the associated control circuitry guarantee that the high-side switch is only enabled after the low-side switch is disabled. This feature provides extra protection against shoot-through and makes the IXDE509SIA particularly suitable for half-bridge and full-bridge applications.The IXDE509SIA also offers a wide array of protection features, including an under-voltage lockout (UVLO), an over-current protection (OCP), short-circuit protection (SCP), overtemperature protection (OTP), and an overload protection (OLP). The IXDE509SIA also offers a built-in booster supply, providing an output voltage of 15V that is internally regulated against VDD, allowing the device to drive higher power MOSFETs and IGBTs.In addition, the IXDE509SIA offers a wide range of configuration options, allowing designers to tailor the device to the application. There are two logic inputs for each channel (IN1 and IN2), which can be used to control the high- and low-side switches. The logic levels of these pins can be either TTL- or CMOS-compatible (3.3V or 5V). There is also an EN pin to enable or disable the device.The operation of the IXDE509SIA is based on an advanced, proprietary high-performance, low-noise, high-side/low-side drive architecture with integrated switch control, current-sensing, and internal regulation. The IXDE509SIA provides a 5A peak current high-side output, as well as a 5A peak current low-side output. This allows it to drive high-power FETs and IGBTs. Both the high- and low-side outputs are connected to a floating bootstrap bus.The IXDE509SIA features an on-board controller that manages the operation of the high-side and low-side switches. The device can be configured for either Flip-Flop or PS/SP mode. In Flip-Flop mode, the high-side switch is enabled when the IN1 pin is low, and the low-side switch is enabled when the IN2 pin is low. In the PS/SP mode, the device can be triggered with a pulse train on the IN1 and IN2 pins.When enabled, the IXDE509SIA implements the reverse-blocking feature, ensuring that the high-side switch is only enabled after the low-side switch is disabled. This helps to prevent shoot-through, as well as providing additional protection against catastrophic faults.In addition to its power supply, the IXDE509SIA also has a wide selection of protection features. These include an under-voltage lockout, an over-current protection, a short-circuit protection, an overtemperature protection, and an overload protection. These features help to ensure that the device will remain functional, even in extreme environmental conditions.The IXDE509SIA is well-suited for various types of switching applications, including motor drives, power converters, DC-DC regulators, lighting, and lighting controllers. The device is available in a compact 24-pin package and is rated for a maximum junction temperature of 125°C.In summary, the IXDE509SIA is an advanced, low-noise, high-performance gate driver which provides a 5A peak current high-side and 5A peak current low-side output, as well as a wide range of protection features. Its reverse-blocking capability and integrated switch control, current-sensing, and regulation make it an ideal choice for half-bridge and full-bridge applications. Furthermore, the device is available in a compact package, making it suitable for various types of switching applications.
