[图]POWR1220AT8设计的12V热插拔技术
ispPAC-POWR1220AT8集成了在系统可编程逻辑和在系统可编程模拟功能,是通用的电源监视器,顺序和余量控制器,它提供12个单独的模拟输 入通道,用来监视多达12个电源测试点. POWR1220AT8提供和IPMC标准的命令接口,能把板上的DC/DC转换器转换成精密的数控电源.本文介绍了ispPAC- POWR1220AT8主要特性,方框图,以及应用方框图, 评估板外形图,采用ispPAC-POWR1220AT8的12V热插拔控制器参考设计电路图.
ispPAC- POWR1220AT8典型应用:
The Power Manager II POWR1220AT8 provides a standard command interface to the IPMC while performing FRU specific payload power management functions using the on-chip CPLD. The POWR1220AT8 also converts all on board DC-DC converters into accurate digitally controlled supplies.

The PAC-POWR1220AT8 evaluation board allows the designer to quickly configure and evaluate the ispPAC-POWR1220AT8 device on a fully assembled printed-circuit board. The four-layer board supports a 100-pinTQFP package, pads for user I/O, a JTAG programming cable connector, and a connector for the device’s I2C interface. JTAG programming signals can be generated by using an ispDOWNLOAD® programming cable connected between the evaluation board and a PC. Both analog and digital features of the ispPACPOWR1220AT8 device can be easily configured using PAC-Designer® software.
