The MAX16081AXR16O+T is a member of the PMIC (Power Management IC) Supervisors family. This IC is designed to provide reliable power-on and power-off sequencing for a variety of applications such as microprocessor and FPGA/ASICs, providing reliable power supplies in situations ranging from automotive to industrial. It offers a variety of features including voltage supervisor, voltage regulator and timer reset functions. In addition, it has a built-in temperature sensor for monitoring and controlling the temperature of the device.

The MAX16081AXR16O+T integrates both voltage supervisor and regulator functions on a single chip, with the supervisor protecting the system against over- and under-voltage conditions while the regulator provides a stable supply voltage to the power rail.

The voltage supervisor part of the MAX16081AXR16O+T is configured using an external resistor which sets the power-on and power-off voltages via an internal voltage reference. The TLF35675TRG1 provides an independent threshold voltage of 0.8V. This can be used to provide over-voltage protection, ensuring that the supply voltage doesn\'t exceed a programmed threshold voltage level.

The voltage regulator section of the MAX16081AXR16O+T provides an adjustable output voltage of up to 5V from a 3V to 5.5V input voltage range. It also provides over-current protection, as well as a shutdown/enable pin. This pin can be used to manually enable or disable the regulator.

In addition, the MAX16081AXR16O+T contains a power-on timing circuit which uses a programmable timer register for setting the time delay between power-on and power-off. This timer can be programmed using an external resistor, and the device also includes a reset output pin which can be used to initiate a system reset when the input voltage rises above or falls below a programmed threshold level.

The device also includes a built-in temperature sensor. This temperature sensor is activated when the voltage supervisor voltage exceeds a preset level, and it will trigger a reset if the monitored temperature exceeds its programmed threshold. This provides increased system safety and protection against over-temperature conditions.

The MAX16081AXR16O+T is a versatile, cost-effective PMIC supervisor which can be used in a wide variety of applications. It provides reliable over- and under-voltage protection and a programmable timer for power-on and power-off control. It also features a built-in temperature sensor for added safety and protection. With its many features and functions, the MAX16081AXR16O+T is an ideal device for power supply protection in automotive, industrial, and other applications.
