产品概述
The TMP816 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.The TMP816 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.
