Details

The SI3421DV is a dual-channel current-limited power switch developed by Silicon Labs. It's designed for applications requiring robust protection and control of high-side switches. The device integrates two independent channels with adjustable current limiting and thermal shutdown features. Each channel can handle up to 1.5A continuous current and 2.5A peak current. With its low RDS(on) of typically 110mΩ, the SI3421DV minimizes power dissipation and voltage drop across the switch, ensuring efficient power delivery. Its wide input voltage range of 2.5V to 5.5V makes it suitable for various low voltage applications. The device also features a programmable current limit and fault reporting through a status pin, enhancing system flexibility and diagnostics.Additionally, the SI3421DV incorporates built-in reverse current blocking to prevent unwanted current flow from output to input, safeguarding sensitive components and ensuring system reliability. It is available in compact and thermally enhanced packages, facilitating space-constrained designs and efficient heat dissipation.
