TINY, LOW-POWER, WATCHDOG TIMERS
SUNNYVALE, CA—May 8, 2000—Maxim Integrated Products introduces the MAX6369/MAX6371/MAX6372/MAX6373/MAX6374 watchdog timer supervisory circuits, designed to increase system reliability by detecting code execution errors. These devices supervise microprocessor (µP) activity. When a system is not operating properly, they reset or interrupt the µP to signal a fault condition. Low power consumption of 5µA makes them ideal for battery-operated applications.
These pin-selectable watchdog timers provide 24 unique timing combinations that optimize design flexibility. The watchdog timeout period can be adjusted from 1ms to 60s to accommodate most systems. A start-up delay feature disables the watchdog during power-up or during a change in the watchdog timeout period to allow for full initialization of the system. Start-up delays range from 1ms to 60s.
These devices come in 8-pin SOT23 packages and require no external components, making them ideal for space-limited applications such as hand-held instruments. Other applications include embedded control systems, industrial controllers, and automotive systems. Prices start from $0.98 (2500-up, FOB USA).
