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.

BGA布线指南 BGA CHIP PLACEMENT AND ROUTING RULE BGA是PCB上常用的组件,通常CPU、NORTH BRIDGE、SOUTH BRIDGE、AGP CHIP、CARD BUS CHIP…等,大多是以bga的型式包装,简言之,80﹪的高频信号及特殊信号将会由这类型的package内拉出。因此,如何处理BGA package的走线,对重要信号会有很大的影响。 通常环绕在BGA附近的小零件,依重要性为优先级可分为几类: 1. by pass。 2. clock终端RC电路。 3. damping(以串接电阻、排组型式出现;例如memory BUS信号) 4. EMI RC电路(以dampin、C、pull height型式出现;例如USB信号)。 5. 其它特殊电路(依不同的CHIP所加的特殊电路;例如CPU的感温电路)。 6. 40mil以下小电源电路组(以C、L、R等型式出现;此种电路常出现在AGP CHIP or含AGP功能之CHIP附近,透过R、L分隔出不同的电源组)。 7. pull low R、C。 8. 一般小电路组(以R、C、Q、U等型式出现;无走线要求)。 9. pull height R、RP。 中文DOC,共5页,图文并茂
