Introduction

MAX16046CETN+T is a member of the PMIC (Power Management Integrated Circuit) Supervisors family. It is designed to monitor battery voltage, battery temperature, and system voltage inputs. With an easy-to-use host interface and an integrated temperature sensor, the device is well-suited for portable electronics applications, such as smartphones and notebook computers.

MAX16046CETN+T Application Field

The MAX16046CETN+T is an ultra-low-power system supervisor and battery monitor specifically designed for ultra-low-power portable applications. It features an integrated battery-temperature sensor as well as a low-dropout voltage regulator that provides power to other system ICs while simultaneously monitoring system and battery voltages. The device has an integrated low-power processor that communicates all of the monitored system, battery, and temperature parameters to the host via an I2C communication interface.In portable electronics applications, the MAX16046CETN+T can be used to monitor the battery voltage and temperature, as well as system voltage inputs, to ensure the system remains within its safe operating range. Additionally, it can be used to monitor the battery capacity and provide an alert when the battery is running low. The device is also well-suited for use in industrial, automotive, and defense applications, as it provides several capabilities for monitoring and controlling the system and battery parameters.

Working Principles of MAX16046CETN+T

The MAX16046CETN+T integrates a microcontroller and a battery and system monitoring analog circuit in a single device. The device contains an embedded 16-bit MCU and a precision voltage-sensing comparator, both of which are connected to two or three (depending on the configuration) system and battery inputs.The device contains an embedded I2C/SMBus interface to enable communication with the host system. All monitored system, battery, and temperature inputs are updated periodically and reported to the host system via the I2C/SMBus interface. The device also automatically monitors the battery and system voltages, and can issue alerts when the system or battery parameters are outside a pre-set safe range. Additionally, the device can be configured to automatically perform a reset of the host system in the event that any of the monitored parameters exceed predetermined thresholds. The device also includes an integrated crystal-less clock, allowing it to generate and output an alarm signal at pre-defined intervals.

Benefits of MAX16046CETN+T

The MAX16046CETN+T offers several benefits when used in portable electronics applications, including: • Low power consumption - the device consumes only 150 µA, allowing high power-efficiency even in battery-powered applications. • Multiple inputs - the device can monitor up to three battery and system voltage inputs. • Alerts and resets - the device can issue alerts when the system or battery parameters are outside of the pre-set range, and can also be configured to automatically perform a reset of the host system in the event that any of the monitored parameters exceed predetermined thresholds. • Flexible communication - the device has an integrated I2C/SMBus interface for communication with the host system, and is compatible with a variety of industry-standard I2C/SMBus protocol versions.• High accuracy - the device provides accurate monitoring of system and battery parameters, with an accuracy of ±0.75%, ensuring reliable power control and management. • Small footprint - the device has a compact 3 × 3 mm leadless package, allowing for a smaller form factor in portable electronics. The MAX16046CETN+T offers several features that make it suitable for a wide range of applications, including portable electronics, industrial, automotive, and defense.

Conclusion

The MAX16046CETN+T is an ultra-low-power supervisor and battery monitor designed specifically for use in portable electronics applications. It features several benefits, including low power consumption, multiple input monitoring, alerts and resets, flexible communication, high accuracy, and a small footprint. The device is suitable for a wide range of applications, including portable electronics, industrial, automotive, and defense.
