MAXIM INTEGRATED PRODUCTS  MAX6303CUA+  芯片, 微处理器监控器, 5.5V, UMAX-8

The is a +5V, low power microprocessor µP supervisory circuit with adjustable reset/watchdog in 8 pin µMAX package. This supervisory circuit provides maximum adjustability for reset and watchdog functions. The reset threshold can be adjusted to any voltage above 1.22V using external resistors. In addition, the reset and watchdog timeout periods are adjustable using external capacitors. A watchdog select pin extends watchdog timeout period to 500x. The reset function has immunity to power supply transients. The MAX6303 is used in intelligent instruments, battery powered computers/controllers, embedded controllers and critical µP monitoring applications.
