ADM1025A集成電路（IC）的專用規(guī)格書PDF中文資料

ADM1025A屬于集成電路（IC）的專用。由安森美半導(dǎo)體公司制造生產(chǎn)的ADM1025A專用該系列產(chǎn)品可提供所需的功能，用以將信息源/信宿連到各種復(fù)雜或范圍狹窄應(yīng)用中的傳感器、變送器、致動器、傳輸介質(zhì)或其他此類端點。例如，汽車安全氣囊驅(qū)動器、車身控制和信息娛樂總線、自適應(yīng)電纜均衡器、智能卡等等。

PRODUCT DESCRIPTION

The ADM1025/ADM1025A is a complete system hardware monitor for microprocessor-based systems, providing measurement and limit comparison of various system parameters. Five voltage measurement inputs are provided for monitoring 2.5 V, 3.3 V, 5 V, and 12 V power supplies and the processor core voltage. The ADM1025/ADM1025A can monitor a sixth power supply voltage by measuring its own VCC. One input (two pins) is dedicated to a remote temperature-sensing diode, and an on-chip temperature sensor allows ambient temperature to be monitored. The ADM1025A has open-drain VID inputs while the ADM1025 has on-chip 100 k? pull-ups on the VID inputs.
