DS1708RESA+

The DS1708RESA+ is a highly advanced microprocessor supervision device from Maxim Integrated. It is designed to ensure the proper power-up of computing systems, fault detection and reporting, and system supervision. This device combines voltage, frequency, and temperature monitoring with multiple time-outs, reset signals, alarm reporting, and fault detection. With these features, the DS1708RESA+ is ideal for a wide range of applications, including portable products and distributed intelligence systems.

The DS1708RESA+ belongs to the group of PMIC (Power Management IC) Supervisors. It is used to monitor the system power supply and to provide an indication of a possible fault condition. The device monitors both the voltage and the frequency of the supply voltage and sends a reset signal to the microcontroller if an unwanted power disruption or inadvertent mistake happens. Additionally, the device is able to provide an audio or visual indication of a fault to a user.

The main working principle of the DS1708RESA+ PMIC Supervisor IC is based on the reliable monitoring of both supply voltage and supply frequency. The device continuously monitors the current value of the supply voltage and the frequency and compares it with a pre-programmed nominal value. When the current measurements are outside the specified limits then the device latches a reset line. The reset line is then used to tell the microcontroller what has happened and to take any remedial action as required. Thanks to its latchable reset line, the DS1708RESA+ can be used in multiple power supply and power management scenarios where either voltage, frequency, or temperature monitoring is required.

The features that make the DS1708RESA+ the ideal PMIC Supervisor IC for multiple types of applications are its wide range of voltage monitoring and its frequency accuracy. This device is able to monitor voltages in the range between 1.5V and 5.5V and it has an impressive accuracy of ±0.02% in frequency measurements. Moreover , the device has an integrated voltage detector that can detect 1.7V to 2.4V.

The DS1708RESA+ PMIC Supervisor IC can be used in a wide range of applications, from automotive to medical, to industrial control and energy management. Due to its superior reliability and accuracy, the device makes a great choice for applications where high robustness and safety are a priority.

In conclusion, the DS1708RESA+ is a versatile PMIC Supervisor IC ideal for multiple applications thanks to its wide range of voltage monitoring capabilities and accurate frequency measurement. The device offers superior reliability and accuracy, making it an excellent choice for applications where robustness and safety are important.
