Introduction

Power management integrated circuit (PMIC) is an integrated circuit (IC) designed to manage power in a system, including data processors and other components. PMICs are used in a wide variety of applications, from personal electronics to wearable and automotive devices. Among them, supervisors, also known as power supervisors, are specialized PMICs that are designed to monitor different power domains, detect fault conditions, provide protection, and take corrective action when required. The MAX6702ARKA+ is a supervisor IC with adjustable, uncommitted output and low-current input, designed to monitor power rails, such as battery and system power, and alert the system when the voltage exceeds a programmed threshold. Additionally, the MAX6702ARKA+ provides a regulated enable output to provide pre-defined enable pins for downstream devices.

MAX6702ARKA+ Application Field and Working Principle

The MAX6702ARKA+ is designed to monitor and control different power domains, detect and trigger fault conditions, and take corrective action when required. It is typically used in battery-operated equipment, such as wearables and consumer electronics, automotive systems, and industrial devices. In each application, the MAX6702ARKA+ can be used to monitor multiple system voltages, with additional monitoring and protection features, including over-voltage, under-voltage, reverse-voltage, and over-temperature conditions.

Monitoring and Protection Features

The MAX6702ARKA+ is designed for maximum reliability, with comprehensive monitoring and protection features. These include over-voltage monitoring and protection (OVP), under-voltage monitoring and protection (UVP), reverse-voltage monitoring and protection (RVP), over-temperature monitoring and protection (OTP), and power-on reset (POR) features. If a monitored voltage falls outside its programmed thresholds, the device will alert the system, or shut down power to protect downstream components.

Regulated Enable Output and Low-Current Input

The MAX6702ARKA+ features a regulated enable output that provides pre-defined enable pins for downstream devices. The enable output is adjustable and uncommitted, allowing designers to easily meet the needs of their particular application. Additionally, the device features a low-current input to reduce power dissipation and maintain colder operation.

Factory-Programmable OVP and UVP Thresholds

The MAX6702ARKA+ offers factory-programmable over-voltage and under-voltage protection thresholds. This allows designers to customize the device to their unique application requirements. The adjustable thresholds help to ensure that only valid voltages are supplied to downstream components.

Conclusion

In conclusion, the MAX6702ARKA+ is a powerful PMIC supervisor that can monitor multiple power rails and issue alerts or take corrective action to protect downstream components when needed. It is suitable for a wide range of applications, from wearables to automotive and industrial devices. Additionally, the device features a regulated enable output and low-current input to reduce power dissipation and maintain cooler operation. The MAX6702ARKA+ offers adjustable UVP and OVP factory-programmable thresholds, enabling designers to customize the device for their particular application.
