The MAX6374KA is a watchdog supervisory circuit from Analog Devices, designed to monitor microprocessor activity and assert a reset if the system fails to strobe the watchdog input within a programmed timeout window. Both the reset timeout and the voltage threshold are adjustable or selectable via pin-strapping, giving the designer flexibility to match the supervisor to the specific processor timing and supply rail.
The small footprint and low pin count make it a natural fit for space-constrained designs such as portable instruments, sensor nodes, or embedded control modules where a dedicated watchdog is needed alongside the main processor.
Lifecycle and compliance
Note that this part is marked RoHS non-compliant, so it is not suitable for assemblies requiring RoHS exemption-free compliance; verify your project's environmental requirements before specifying.
