PMIC (Power Management Integrated Circuit) supervisors are essential components in many electronic systems. They provide the necessary system monitoring and protection by enforcing voltage and temperature thresholds and resetting the system when those thresholds are exceeded. The MAX6795TPWD2+ device is a precision, low-power supervisor for multiple power rails that provides system monitoring, protection and control for advanced portable applications.

The MAX6795TPWD2+ device combines several features, including system reset (or RESET) generation, voltage monitor (VMON) and system state monitoring (SSM) outputs. The voltage monitor output is a low-voltage comparator that can be configured to monitor up to three system supply rails at adjustable differential thresholds as low as 0.7V. The threshold is programmable to any voltage between 0.7V and 2.95V through a simple, microprocessor-compatible interface. The MAX6795TPWD2+ can be configured to drive an active-low RESET output in five different ways. The RESET output can be configured to respond to voltage and temperature thresholds, manual reset, power-on reset and a programmable delay.

The SSM output is a logic signal indicating the system’s power-on status, signal integrity and voltage monitoring. The SSM output is typically used to indicate when power-on is complete for programmable initialization. The MAX6795TPWD2+ device also integrates an on-chip temperature sensor to monitor ambient temperature. The temperature sensor can be used to generate an active-low RESET signal when the temperature exceeds an adjustable temperature threshold. The thermal alarm threshold is programmable and is adjustable over a range of -40℃ to +125℃.

The MAX6795TPWD2+ offers protection against over-voltage on up to three supplies and offers a watchdog timer and power supply sequencing feature. The device operates with a 2.95V to 5.5V supply voltage, but it is pin-compatible with the 3.3V MAX6783TPW to provide 2V to 5.5V operation. With its low quiescent current of 6µA and sleep current of 0.45µA, the MAX6795TPWD2+ is ideal for portable and battery-powered applications.

The MAX6795TPWD2+ is used in a wide range of applications, including personal computers and notebook computers, mobile phones and handheld devices, medical and industrial equipment, automotive applications, and gaming and consumer electronics. It also is suitable for use in applications where system reliability, safety and accuracy are essential, such as avionics and military systems.

In summary, the MAX6795TPWD2+ is a precision, low-power supervisor for multiple power rails that provides system monitoring, protection and control for advanced portable applications. It offers protection against over-voltage on up to three supplies and offers a watchdog timer and power supply sequencing feature. It is used in a wide range of applications, including medical and industrial equipment, automotive applications, and gaming and consumer electronics. With its 6µA quiescent current and 0.45µA sleep current, the MAX6795TPWD2+ is ideal for portable and battery-powered applications.
