PMIC - Supervisors are one of the most important categories of power management ICs. They are used to control, monitor and protect a wide range of electronic systems. The MAX6464XR46+T is a family of voltage supervisors that provide improved accuracy, accuracy over temperature, and enhanced protection from destructive overvoltage conditions. It joins MAX’s family of low-voltage, low-current, high-accuracy voltage supervisors.

The MAX6464XR46+T is a single-channel voltage supervisor that monitors one power-supply input and provides active-low reset and reset-status-interrupt signals. It operates with either a single or dual supply, between 2.3V to 5.5V and is fully specified over the extended temperature range of -40°C to +85°C.The MAX6464XR46+T promises amazing flexibility in voltage-detection designs with the ability to configure 64 different combination of VIN_th, VOUT, POR, and reset delay protocol.The Multiple-Threshold System with foldback system offers customers significant cost savings by allowing them to use a single supervisor IC instead of multiple ICs with different trip-point thresholds.

The MAX6464XR46+T offers excellent accuracy and excellent accuracy over temperature as compared to its nearest competitors.It provides well-defined reset thresholds, making it perfect for systems that require very low to moderate current consumption and high accuracy.It has programmable reset delay and timeout features that enable customers to create power-up and power-down sequences, as well as time-out safety features for battery-operated systems.

The MAX6464XR46+T is ideally suited for a wide range of applications such as battery-operated applications, embedded systems, digital logic, automotive systems, system health/integrity monitoring, and server/storage systems. In addition, it supports a wide array of voltage-source configurations, such as extending the reset signal to systems powered by batteries and by powered rails, including AC adapters, alternators, and solar sources.

The MAX6464XR46+T operation is based on a comparator using a voltage reference, which is configurable via the device\'s register. The supervisor continuously monitors the voltage on its input, VIN, and will generate the reset signal when VIN is higher than its warning and reset thresholds or < VIN < its reset threshold, depending on the delay configuration. Additionally, the device provides an active low interrupt signal to allow the microcontroller to enter a low-power state when the input voltage is too low.

In summary, the MAX6464XR46+T provides resources to economically implement a wide range of voltage supervisors in a single-channel configuration. With its easily configurable parameter settings and exacting accuracy, it is the ideal solution for any system requiring reliable monitoring of the input voltage. Additionally, its ease of use is a plus for system developers and should offer a significant improvement in terms of cost savings.
