Onsemi FDC6330L Single-Channel Load Switch 20V SSOT-6

Onsemi FDC6330L Single-Channel Load Switch is a 20V high-side load switch in a compact 6-pin SSOT package, designed for managing power distribution in portable and battery-operated devices. It uses a small N-channel MOSFET to drive a larger P-channel power MOSFET, allowing it to handle significant load currents.

Overview

The FDC6330L combines PowerTrench technology with an on-state resistance (Ron) of 0.054Ω (typical), which helps to limit power loss and heat generation during operation. It supports a continuous load current of 2.3A, with pulsed currents of up to 10A, and operates across a temperature range of -55°C to 150°C.

Protection

The control MOSFET includes integrated Zener diode protection, offering Electrostatic Discharge (ESD) immunity exceeding 6kV on the Human Body Model. The device also includes thermal protection against overheating.

Applications

The active-high enable switch is suited to controlling subsystems, peripherals, or entire circuit blocks. Its compact footprint supports power sequencing and allows unused sections of a circuit to be completely shut off, helping to save energy.
