Applications of MAX793TESE+ IC

The MAX793TESE+ IC is suitable for a variety of applications, and is commonly used in applications such as wearable devices, battery management systems, and mobile phone charging systems. It can also be used in automotive applications, as it has an extremely low quiescent current and an ultra-low UVLO threshold, making it suitable for a variety of operating conditions. Furthermore, the integrated watchdog timer provides a reliable level of system protection. Additionally, the IC is suitable for applications where a battery needs to be monitored, as the dual battery support allows for two batteries to be monitored simultaneously.

Working Principle of MAX793TESE+ IC

The MAX793TESE+ IC is a supervisor IC that monitors system conditions and provides multiple resources for system protection. The first step of the working process is to detect the system voltage and temperature through the integrated voltage and temperature sensing circuits. The IC is then able to monitor the under-voltage lockout (UVLO) threshold and check to make sure the system is operating within an acceptable range. If the voltage or temperature falls below the preset threshold, then the IC will trigger the watchdog timer to reboot the system.

The IC also features dual battery support, allowing it to monitor two batteries at the same time. The IC is able to detect the voltage and temperature of each battery, and will send an alert if the voltage falls below a certain threshold. Additionally, the IC can also be used to detect overvoltage conditions and will trigger the integrated watchdog timer to reboot the system if necessary.

The MAX793TESE+ also features a variety of push-pull outputs and open drain outputs, providing flexibility in the design of the circuit. The outputs can be used to control external circuits or provide system indications such as power on or alert signals. Additionally, the integrated watchdog timer can be programmed to reset the system in the event of a system fault or malfunction.
