AO6409 Description

Short technical summary and product information.

The AO6409 is a P-Channel enhancement-mode MOSFET fabricated using advanced trench technology to achieve low on-resistance and low gate charge. It is designed for load switch applications where efficient power management is required. The device supports gate drive voltages as low as 1.8V, making it suitable for low-voltage logic level control.

 

Key electrical specifications include a maximum drain-source voltage of -20V, continuous drain current of -5.5A at 25°C ambient (derated to -4.2A at 70°C), and pulsed drain current capability up to -30A. The static drain-source on-resistance is typically 34mΩ at Vgs=-4.5V and Id=-5.5A, with a maximum of 41mΩ. The gate threshold voltage ranges from -0.3V to -0.9V, ensuring reliable turn-on at low gate voltages.

 

The device is housed in a 6-pin TSOP package (SC-74/SOT-457) and is qualified for surface-mount assembly. It operates over a junction temperature range of -55°C to 150°C, with thermal resistance junction-to-ambient of 48°C/W (typical) for short pulse conditions. The AO6409 also includes ESD protection, enhancing its robustness in handling and assembly.
