The MAX6887DETE+ is a Low-Voltage Supervisors with Advanced Reset and Watchdog Features, which is the combination of Power Management and System Supervisory application fields and working principles.

The MAX6887DETE+ is typically used in applications that require multi-purpose sequencing, monitoring, and control of multiple power sources and/or functions. For example, they can be used as power sequencing supervisors to ensure that all necessary operations are performed when the system is turned on, and then to prevent unnecessary operations when the system is turned off. Additionally, they can be used for reset, watchdog, and system control functions in applications that require a wide range of power management, supervisor, and system control features.

The MAX6887DETE+ is an advanced, ultra-low voltage polyfuse system supervisor. It has an adjustable trip voltage of 0.90V to 0.45V (in 0.15V steps), and it supports both a latched output and a non-latched reset option. The watchdog timer has a programmable timeout of 15s to 31s (in 15s steps), providing flexible and reliable system monitoring.

The MAX6887DETE+ integrates an undervoltage detector, an adjustable reset timer, a capacitor-controlled reset generator, and a watchdog timer in a tiny 3mm2 package. It provides adjustable reset monitoring thresholds, an adjustable reset timer, a watchdog timer, and an active-low reset output.

The undervoltage monitoring function has adjustable thresholds and an output signal that is asserted before the output reset is generated. The adjustable reset timer is used to delay the generation of the active-low reset output after the undervoltage condition has been detected. On the other hand, the watchdog timer is used to generate a reset signal in case of system lock up or malfunction. The reset generator is triggered by either the undervoltage detection or the watchdog timer to generate a reset signal of controlled duration.

The MAX6887DETE+ is designed for applications that require reliable system supervision, and it supports a wide range of chip technologies, including digital large-scale integration (LSI), random logic, and microprocessor-based systems. The device supports "sleep" mode features to reduce system power, and it can be easily programmed using a serial port or via I2C communication.

The MAX6887DETE+ is suitable for applications such as power related, watchdog functions, system control, reset functions and low power signal conditioning. The device is suitable for a wide range of consumer, industrial, and medical products in which it is essential to have reliable system supervision. The device provides reliable operation, low power consumption, and is ideal for space-constrained applications.
