A gate driver is a power electronic component used to manage the power of an electronic device. It is an integrated circuit that directs the high-power switches of an electrical circuit. TC4467EP is a gate driver from the power management IC family of products from Texas Instruments. This driver offers high current-handling capability and wide dynamic range, enabling it to be used in many high-end applications.

The TC4467EPD is a monolithic half-bridge gate driver specifically designed to drive power MOSFETs or IGBTs. It is a dual high-side driver that can handle up to 20A peak output current in pulsed regimes and to 5A continuous output current. It also has a built-in fault protection feature, which eliminates the need for the usual external components used in similar applications. The device is designed to be used in applications with high supply voltage, up to 80V.

The TC4467EPD has two wide-input CMOS inputs for the low-side and high-side MOSFET driver outputs. It also has two enable/disable capability pins for the two individual outputs, which can be used to control the functionality of the inputs or shut down the outputs. The enable pins have a wide input range, which makes them compatible with any logic supply. This feature is especially beneficial in multi-phase applications, where the enabling of one phase can be controlled by the enable pin of the other.

This device has integrated protection features to provide an extra level of safeguard from transient events, fault conditions, and even overvoltage and undervoltage situations. It includes fault condition monitoring, undervoltage lockout, overvoltage lockout, over-temperature protection, over-current monitoring, and open-drain outputs. This makes the TC4467EPD a very reliable and safe device for use in high-end applications, where safety and robustness are critical.

The TC4467EPD also has an internal low standby power consumption of 3µA, making it ideal for battery-powered and other low-power applications. This allows the device to be used in applications that must operate in low-power mode, such as wearables or IoT devices. In addition, the device has an internal pulse-by-pulse current limiting feature, which helps protect itself and the load against overload conditions. The device is available in 3 different packages: SO-8, TSSOP-16, and micro8W, which makes it suitable for a wide range of applications.

In conclusion, the TC4467EPD gate driver is a highly integrated, high-performance dual-channel, high-side MOSFET driver with features and capabilities that make it suitable for many applications, such as motor control, high-power LED, automotive, illumination, and many others. It provides excellent current-handling capacity and feature rich protection, with a very low standby current consumption, making it an excellent choice for many high-end applications.
