The MAX6701ASKA+ is a Low Voltage Supervisor with an adjustable reset threshold and two watchdog inputs (WDI and WDC). The MAX6701ASKA+ monitors voltages in mobile systems to insure system integrity and provide alerting to system health and errors. This device can also be used to reset or power-down a system in conditions where voltage levels do not meet specified parameters or watchdog latencies are too long. This type of supervisor is a Power Management Integrated Circuit (PMIC) known as a supervisor.

The MAX6701ASKA+ contains a wide reset input voltage range (1.6V - 3.6V). It also provides multiple phases of reset and power monitoring. This device can monitor voltage levels from 1.6V up to 4.085V (VCC1). Additionally, this device provides an adjustable reset output threshold which is factory programmed from 1.6V up to 4.085V (VCC1). Moreover, the device also has two watchdog inputs (WDI and WDC) which can be separately configured for either active high or active low detection.

The working principle of the MAX6701ASKA+ is that it tracks the voltage over time. If it falls below its specified voltage level, the device will issue an alert by pulling the reset (RESET) line low. Similarly, if a watchdog input (WDI or WDC) is in an active state for longer than the set timeout period, a reset can also be issued. This reset will continue to stay low until the voltage levels return to normal and the device has been fully cycled.

With its adjustable reset output threshold and dual watchdog inputs, the MAX6701ASKA+ is a useful device for systems where power and logging integrity are paramount. It can be used to power down or reset a system in the event of a malfunction, or to trigger an alert or power-down when voltage levels fall outside acceptable limits. Additionally, it can also be used to monitor the voltage of high-power peripherals such as high-voltage regulators and other power-hungry components. This ensures that their power supply remains constant, minimizing breaks or disturbances in the system.

In summary, the MAX6701ASKA+ is a PMIC (Power Management Integrated Circuit) supervisor that monitors voltage levels and triggers certain actions if the voltage becomes too low or if a watchdog input remains active for too long. With its adjustable reset threshold and two watchdog inputs, this device is suitable for use in a variety of applications where system power and logging integrity are imperative.
