Product introduction：
1. MI4966-VB Product Introduction
MI4966-VB is a high-performance dual N-channel MOSFET in SOP8 package, designed for low voltage applications. The device has a rated drain-source voltage (VDS) of 20V, capable of handling higher voltages, while its gate-source voltage (VGS) range is ±12V, providing flexible control options. The threshold voltage (Vth) of MI4966-VB is between 0.5V and 1.5V, ensuring fast turn-on at a lower gate voltage.
In the on state, the device exhibits excellent conduction performance: the on-resistance (RDS(ON)) is 26mΩ at VGS of 4.5V, and decreases to 19mΩ at VGS of 10V. This allows MI4966-VB to maintain low power loss even under high current conditions, thereby improving system efficiency. The device has a maximum continuous current (ID) of up to 7.1A, making it ideal for a variety of power management and control applications.
MI4966-VB uses advanced Trench technology to reduce on-resistance and switching losses, improving overall system performance.
