LM621无刷电机换向器
资料介绍
General Description
The LM621 is a bipolar IC designed for commutation of
brushless DC motors. The part is compatible with both
three- and four-phase motors. It can directly drive the power
switching devices used to drive the motor. The LM621 provides
an adjustable dead-time circuit to eliminate ``shootthrough''
current spiking in the power switching circuitry.
Operation is from a 5V supply, but output swings of up to
40V are accommodated. The part is packaged in an 18-pin,
dual-in-line package.
