The MAX6373KA+ is a precision watchdog timer designed for critical microprocessor applications. It supervises microprocessor activity and signals when a system is operating improperly. During normal operation, the microprocessor must repeatedly toggle the watchdog input (WDI) before the selected timeout period elapses. If this does not occur, the supervisor asserts a watchdog output (WDO) to indicate a processing error.
This device operates over a +2.5V to +5.5V supply range and features pin-selectable watchdog timeout periods and startup delay periods. The watchdog output is active-low and can be configured as open-drain or open-collector. It requires no external components and is available in a miniature 8-pin SOT-23 package.
Key features include a low supply current of 8μA, adjustable/selectable reset timeout, and an adjustable/selectable voltage threshold. The operating temperature range is -40°C to +125°C (TA). This supervisor is suitable for embedded control systems, industrial controllers, and critical μP and microcontroller monitoring.
The MAX6373KA+ is surface-mountable in a SOT-23-8 package, making it suitable for space-constrained designs.
