Introduction

The MAX708SESA+T is a circuit supervisor device designed by Maxim Integrated, part of the MAX70 Supervised Micro-Power Circuit Supervisors series. This supervisors device is typically used to ensure proper circuit operation and battery charging in a wide range of electrotechnical applications. The MAX708SESA+T pin-compatible replacement of the MAX708ESA+/MAX708SA+ offers improved standby current and a reset voltage range improved from 2.6V to 4.38V, allowing designers to extend battery runtime in their applications. This article will explain application fields and working principles of the MAX708SESA+T.

Application Fields

The MAX708SESA+T is well-suited for a wide spectrum of portable device applications and mobile computing platforms such as personal digital assistants (PDAs), military handheld equipment, cell phones and wireless data/voice communication systems. The supervisor device is also suitable for industrial field portable maintenance, medical and health care equipment, automotive systems and portable instrumentation.

The MAX708SESA+T provides a wide array of salient features, such as low power consumption, high accuracy and an improved reset voltage range. These features make the MAX708SESA+T function ideally in portable instrumentation platforms; it ensures proper circuit operation and reliable battery charging, while consuming less power and providing higher accuracy than prior series.

Working Principle

The MAX708SESA+T is designed to work as a low-voltage batter supervisor and provide user system protection and accurate brownout detection. The device consists of a logic reset, a power-fail input, a reset output, an overtemperature warning and an undervoltage warning. During the power-up sequence, the MAX708SESA+T will detect and monitor the device\'s voltage level, making sure that it is above the user-defined reset threshold. When an overvoltage or undervoltage condition occurs, the MAX708SESA+T will signal an overtemperature or an undervoltage warning, depending on the voltage level. On the other hand, the MAX708SESA+T includes a power-fail input that will trigger the reset output, alerting the user system in the presence of a low battery.

When a power-fail signal is produced due to a low battery, the MAX708SESA+T will immediately initiate a brownout reset sequence, signaling the user system to enter system-power-down mode in order to preserve remaining battery power. The MAX708ESA+/MAX708SA+-family devices feature an improved reset voltage range, allowing designers to extend battery runtime. Finally, the MAX708SESA+T provides push-button reset input, which may be used to force a system reset if necessary.

Conclusion

The MAX708SESA+T is a low-power, supervised circuit device that is suitable for a wide range of power management applications, such as PDAs, military handhelds, cell phones, wireless data/voice communication, industrial field maintenance, medical and health care equipment, automotive systems and portable instrumentation. The supervisor device is designed to detect and monitor the device\'s voltage level, providing accurate brownout detection, overtemperature and undervoltage warnings. In addition, it offers push-button reset input, making it ideally suited for a wide range of power management applications.
