Introduction

MAX707ESA+T is a highly integrated and versatile power management IC (PMIC) supervisor from Maxim Integrated. It is designed for use in wide variety of consumer, industrial and communications applications. The device features a programmable reset with manual reset option, adjustable voltage monitoring, a regulated ultra low quiescent current and high accuracy, low noise 3.2V power-on sequence. The device is ideal for battery-operated applications, automotive, consumer and communications systems.

Application Field and Working Principle

The MAX707ESA+T finds applications in a variety of consumer, industrial and communications devices. In consumer and electronic design, the device is used to monitor the voltage levels and reset the system in case of an overvoltage event, eliminating the need for discrete components. In automotive and communication systems, the MAX707ESA+T is used to ensure safe power-on sequence and to protect the system from voltage spikes during power-up.The MAX707ESA+T uses a unique, patented programmable reset with manual reset option to provide an adjustable voltage monitoring feature. The device monitors input voltage levels and resets the entire system if the voltage exceeds the preset limit. The device also features an adjustable reset timer, an adjustable timeout period, a regulated ultra low standby current and an open drain RESET output.The MAX707ESA+T can also be used to guarantee a precise power-on sequence in a system. The device ensures that all the associated power systems and components are powered on in the correct sequence and with the correct voltage levels. This prevents possible system damage due to incorrect/inadequate power-on sequences.The device can also be used to reduce system power consumption. The MAX707ESA+T is configured with an integrated regulator, low quiescent current and ultra-low power mode that can reduce the system power consumption significantly, without compromising system performance.The MAX707ESA+T also features an adjustable, baud rate generator that can be used to provide precise timing for data transmission and system control operation. The device has been designed to operate at temperatures from −40°C to +85°C, and is also available in an extended temperature version from −40°C to +125°C.

Conclusion

The MAX707ESA+T is a versatile and highly integrated power management IC supervisor designed by Maxim Integrated. It is ideal for battery-operated applications, automotive and communication systems and can be used to provide a precise power-on sequence, reduce system power consumption, ensure safe operation and provide adjustable voltage monitoring. It is available in an extended temperature range and can also be used as a baud rate generator.
