Signal supervisors can be found in a wide variety of applications and systems ranging from embedded systems to industrial applications. The MAX16140B220KM+ supervisory circuit is one example, and is a member of the family of Maxim Integrated’s Supervisors intended for use in systems that need to maintain system and component reset, clock and supply monitoring, and other power management functions. The MAX16140B220KM+ is a triple-wide input, window voltage monitor with manual reset input and watchdog timer with independent reset. This handy supervisor device is a low-power solution that is suitable for use with low-voltage systems. With its extended temperature range, it is suitable for many applications in extreme operation conditions. With an adjustable reset threshold and reset active delay, this supervisor can manage complex power-up, power-down, and reset-sequencing applications with ease.The MAX16140B220KM+ provides precise reset and supply monitoring, with a ±1% of VCC voltage monitoring accuracy. This precise monitoring helps prevent the application from entering into critical or undesirable states during power-up, power-down, or component reset procedures. The reset out polarity is programmable, offering users the flexibility to adapt it to the particular application.The watchdog timer in the MAX16140B220KM+ helps guard against potential unwanted software executions, and it can keep resetting the system until the application enters a defined logical state. The reset active delay of the watchdog timer is adjustable, and the timer can be used to provide an action in response to various external events such as power-failure or input signal timeout. The manual reset feature is a handy feature which can be used to target system reboot in case of an unexpected application halt.The MAX16140B220KM+ has several features and settings designed to protect the application from undesired system state, and it is suitable for many applications in extreme operation conditions. The triple-wide input, window voltage monitor and manual reset input, watchdog timer with independent reset feature make it a great choice for power management and reset monitoring applications.
