Abstract: Some power architectures require the power supply sequencer (or system manager) to controldownstream power MOSFETs to allow power to flow into branch circuits. This application note explains howsystem power sequencing and level shifting can be accomplished using a low-voltage system manager

為降低成本和解決現有膜片鉗放大器系統中PC機的干擾問題，研究了一種基于單片機的膜片鉗放大器小系統。該系統采用ADI公司生產的ADuC841作為控制核心，并且配置相應的液晶顯示模塊LCM3202401。模擬電路部分采用高輸入阻抗的AD8627實現微電流信號的采集，并由后級電路進行信號的放大和電阻電容的補償。它具有硬件電路簡單、體積小、使用方便的特點。既可以單獨作為小系統實現采集和顯示，也可以通過紅外方式和PC機進行通訊，在PC機上進行信號的處理。 Abstract: In order to reduce cost and resolve the interferential problem with PC in existing patch clamp amplifiers, a small patch clamp amplifier system design based on microcontroller is studied. It adopts a new high performance microconverter ADuC841 by the ADI as the control core in the system, configuring a liquid crystal module LCM3202401. In the analog circuit, AD8627 with high input impedance is used to detect the low current，signal magnification, as well as resistance and capacitance compensation are accomplished by subsequent circuits. It has the advantage of simple hardware circuit design, small volume and convenient operation. It can either be used as an independent system to measure and show signal detected or transmit to PC by infrared ray.

The PCA9544A provides 4 interrupt inputs, one for each channeland one open drain interrupt output. When an interrupt is generated byany device, it will be detected by the PCA9544A and the interruptoutput will be driven LOW. The channel need not be active fordetection of the interrupt. A bit is also set in the control byte.Bits 4 – 7 of the control byte correspond to channels 0 – 3 of thePCA9544A, respectively. Therefore, if an interrupt is generated byany device connected to channel 2, the state of the interrupt inputs isloaded into the control register when a read is accomplished.Likewise, an interrupt on any device connected to channel 0 wouldcause bit 4 of the control register to be set on the read. The mastercan then address the PCA9544A and read the contents of thecontrol byte to determine which channel contains the devicegenerating the interrupt. The master can then reconfigure thePCA9544A to select this channel, and locate the device generatingthe interrupt and clear it. The interrupt clears when the deviceoriginating the interrupt clears.
