AO4485 Description

Short technical summary and product information.

The AOS AO4485 is a P-Channel MOSFET utilizing advanced trench technology to achieve excellent on-resistance (RDS(ON)) and low gate charge. This device is rated for a Drain-Source Voltage (VDS) of -40V and a continuous drain current (ID) of -10A at VGS = -10V.

Key electrical characteristics include a maximum RDS(ON) of 15mΩ at VGS = -10V and 20mΩ at VGS = -4.5V. The gate threshold voltage (VGS(th)) ranges from -1.7V to -2.5V. Dynamic parameters such as input capacitance (Ciss) are typically 2500pF, output capacitance (Coss) at 260pF, and reverse transfer capacitance (Crss) at 180pF. Total gate charge (Qg) is 42nC at VGS = -10V.

This MOSFET is housed in an SO8 package and is suitable for surface mounting. Its thermal characteristics include a maximum junction temperature of 150°C and a junction-to-ambient thermal resistance (RqJA) of 75°C/W at 25°C ambient temperature.

The AO4485 is suitable for use in DC-DC converter applications.
