AO4437L

Overview

The AO4437L is a P-Channel Enhancement Mode Field Effect Transistor manufactured by Alpha & Omega Semiconductor. It utilizes advanced trench technology to achieve low gate charge and operation with gate voltages as low as 1.8V. The device features a drain-source voltage of -12V and a continuous drain current of -11A at VGS = -4.5V. On-state resistance is less than 16mΩ at VGS = -4.5V, 20mΩ at VGS = -2.5V, and 25mΩ at VGS = -1.8V. It is housed in an SOIC-8 package and offers an ESD rating of 4KV HBM.

Feature Summary

Advanced trench technology for excellent on-resistance and low gate charge
Capable of operation with gate voltages as low as 1.8V
ESD protected with a 4KV HBM rating

Applications

Load switch applications
PWM (Pulse Width Modulation) applications
