ON Semiconductor FDC6330L Single-Channel Load Switch, 20V, 2.5A, SSOT-6

The ON Semiconductor FDC6330L is a high-performance integrated load switch designed to provide efficient and robust power management in a compact SSOT-6 package. This component is engineered for reliability, incorporating a dual MOSFET architecture where a small N-channel MOSFET drives a larger P-channel power MOSFET to handle significant load currents.

Key to its design is the advanced PowerTrench technology, which delivers an extremely low static on-resistance (Ron) of just 0.054Ω, minimising power loss and heat generation during operation. The switch is built to withstand demanding conditions, with an operating temperature range from -55°C to 150°C and a maximum continuous load current of 2.3A, capable of handling pulsed currents up to 10A.

Enhanced Protection and Reliability

To ensure ruggedness in sensitive electronic environments, the control MOSFET includes integrated Zener diode protection, offering excellent Electrostatic Discharge (ESD) immunity exceeding 6KV on the Human Body Model. This feature makes the FDC6330L suitable for applications where component durability is critical. The device also features thermal protection, safeguarding against overheating.

Applications and Use

This active-high, high-side load switch is ideal for managing power distribution in portable and battery-operated devices. Its compact footprint and efficient performance make it perfect for controlling subsystems, peripherals, or entire circuit blocks, enabling effective power sequencing and saving energy by completely shutting off unused sections.
