技术资料 LM621无刷电机换向器
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 ``s ...

PCB相关 PCB Design Considerations and Guidelines for 0.4mm and 0.5mm WLPs
Abstract: Using a wafer-level package (WLP) can reduce the overall size and cost of your solution.However when using a WLP IC, the printed circuit board (PCB) layout can become more complex and, ifnot carefully planned, result in an unreliable design. This article presents some PCB designconsidera ...

书籍 EDGE+for+Mobile+Internet
The General Packet Radio Service (GPRS) allows an end user to send and
receive data in packet transfer mode within a public land mobile network
(PLMN) without using a permanent connection between the mobile station
(MS) and the external network during data transfer. This way, GPRS opti-
mizes the us ...
