产品概述

The TMP814 is a single-phase bipolar variable speed fan motor predriver that works with an external PWM signal. A highly efficient, quiet and low-power consumption motor driver circuit, with a large variable speed, can be implemented by adding a small number of external components.This device is optimal for driving large scale fan motors (with large air volume and large current) such as those used in servers and consumer products.
