ADM9240 Datasheet PDF

onsemi ADM9240

The ADM9240 is a complete system hardware monitor for microprocessor-based systems, providing measurement and limit comparison of up to four power supplies and two processor core voltages, plus temperature, two fan speeds and chassis intrusion. The high speed successive approximation ADC allows frequent sampling of all analog channels to ensure a fast interrupt response to any out-of-limit measurement. The ADM9240’s 2.85 V to 5.75 V supply voltage range, low supply current and I2C compatible interface, make it ideal for a wide range of applications.

FEATURES

Six Direct Voltage Measurement Inputs (IncludingTwo Processor Core Voltages) with On-Chip Attenuators On-Chip Temperature Sensor Five Digital Inputs for VID Bits Fully Supports Intel’s LANDesk Client Manager (LDCM) Register-Compatible with LM7x Products Two Fan Speed Monitoring Inputs I2C® Compatible System Management Bus (SMBus) Chassis Intrusion Detect Interrupt Output Programmable RESET I/O Pin Shutdown Mode to Minimize Power Consumption Limit Comparison of all Monitored Values

APPLICATIONS

Network Servers and Personal Computers Microprocessor-Based Office Equipment Test Equipment and Measuring Instruments PRODUCT

DESCRIPTION

Measured values can be read out via an I2C-compatible serial System Management Bus, and values for limit comparisons can be programmed in over the same serial bus. These include hardware monitoring and protection applications in personal computers, electronic test equipment and office electronics. FUNCTIONAL BLOCK DIAGRAM VCC VID0 VID1 VID2 VID3 VID4 F...
