Description

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.
