MAX6373KA-T Description

Short technical summary and product information.

The MAX6373KA-T from Analog Devices is a pin-selectable watchdog timer supervisor that monitors microprocessor activity and signals improper system operation. During normal operation, the microprocessor must toggle the watchdog input (WDI) before the timeout period expires. If this does not occur, the supervisor asserts a watchdog output (WDO) to indicate a processing error.

 

This device offers flexibility with pin-selectable watchdog timeout periods, including options for 1ms (push-pull) and 100ms (open drain). It operates over a wide supply voltage range of +2.5V to +5.5V and features a low supply current of 8μA. The watchdog output can be used to reset the microprocessor or interrupt the system.

 

The MAX6373KA-T is housed in a miniature 8-pin SOT-23 package, suitable for surface mount applications. Its design eliminates the need for external components, simplifying system integration. This watchdog timer is ideal for embedded control systems, industrial controllers, and critical microcontroller monitoring applications where system reliability is paramount.

 

Key features include pin-selectable timeout periods, adjustable startup delays, and an active-low watchdog output. The device also includes a watchdog timer disable feature. The operating temperature range is -40°C to 125°C.
