產(chǎn)品描敘

The YX4505 is a high performance single-channel low side gate driver designed for high-speed GaN FET and Si MOSFET applications.

 Its low propagation delay and high peak current make it suitable for a range of applications including LiDAR, time-of-flight, facial recognition, and power converters. 

The YX4505 can deliver high peak current up to 4A source and 8A sink into capacitive load.

 It supports rail-to-rail drive capability and split gate driver, and is TTL logic compliant with 7V maximum input voltage.

The YX4505 features under voltage lockout (UVLO) and over temperature protection (OTP) help ensure the device operating safely and reliably. 

The YX4505 is available in an industry standard small 6-lead DFN 2mmx2mm package with exposed pad and low parasitic inductance and resistance, suitable for high frequency power systems.
