TMP815 变速单相全波风扇电机前置驱动器
The TMP815 is a single-phase bipolar driving motor pre-driver with a variable-speed function that is compatible with an external PWM signal. With few external parts, a highly efficient and quiet variable-drive fan motor with low power consumption can be achieved.
This device is best suited for driving of the servers requiring large air flow and large current or the fan motors of consumer appliances
