Current Limiter Circuit Incorporated

ORDERING INFORMATION

–

Chopper type current limiting made at

startup and during lock

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

highly efficient and quiet

variable-drive fan motor with low power consumption

can be achieved.

Reactive Current Cut Circuit Incorporated

–

Reactive current before phase change is

cut to enable silent and low-consumption

drive
