MAX1232：微处理器监测器

升级后的MAX1232使功耗降低10倍

The MAX1232 microprocessor (µP) supervisory circuit provides µP housekeeping and power-supply supervision functions while consuming only 1/10th the power of the DS1232. The MAX1232 enhances circuit reliability in µP systems by monitoring the power supply, monitoring the software execution, and providing a debounced manual reset input. The MAX1232 is a plug-in upgrade of the Dallas DS1232. A reset pulse of at least 250ms duration is supplied on power-up, power-down, and low-voltage brownout conditions (5% or 10% supply tolerances can be selected digitally). Also featured is a debounced manual reset input that forces the reset outputs to their active states for a minimum of 250ms. A digitally programmable watchdog timer monitors software execution and can be programmed for timeout settings of 150ms, 600ms, or 1.2s. The MAX1232 requires no external components.

关键特性 Consumes 1/10th the Power of the DS1232 Precision Voltage Monitor—Adjustable +4.5V or +4.75V Power-OK/Reset Pulse Width—250ms Min No External Components Adjustable Watchdog Timer—150ms, 600ms, or 1.2s Debounced Manual Reset Input for External Override Available in 8-Pin PDIP/SO and 16-Pin Wide SO Packages
