SP708TEN-L

Supervisors are a set of power management ICs that are used to control microcontroller systems. They are used to control and detect power-on reset, power good, and power fail operations. For a system to remain stable, the power supplies must remain within an acceptable range. Supervisors ensure a safe transition from one power supply to another, eliminating the chance of system hang-up due to sudden power supply changes. One of the most popular supervisor ICs is the SP708TEN-L. This IC is widely used in embedded systems and can be used for a variety of applications.

Application Field

The SP708TEN-L is a multi-voltage monitoring IC. It supports monitoring from 0.9V to 5.5V, making it a great choice for embedded systems. It is used to monitor voltages and detect when they are out of the acceptable range. It is able to detect as low as 0.45V, making it suitable for a wide range of systems. It also includes an active-low output that can be used to trigger an interrupt, making it ideal for non-critical applications such as battery and voltage monitoring. Additionally, it can be used as a reset IC that can detect fault conditions and prevent the system from entering an unstable state.

The SP708TEN-L is also widely used in automotive applications. It can be used to monitor battery voltage and supply levels, ensuring that the system remains within an acceptable range. It is also used to detect when the ignition is turned on and off, allowing for automated control processes to be performed.

Working Principle

The SP708TEN-L is a low-voltage monitor with active-low output. It works by continuously monitoring the voltage levels supplied to it and comparing them to the nominal level. When the voltage level drops below the nominal level, the output pin will become active, allowing the system to detect the fault condition. Additionally, it can be configured to detect overvoltages, ensuring that the voltage stays within the acceptable range. Furthermore, it can also be used to generate a reset signal in case of a power supply fault, ensuring that the system remains stable.

The SP708TEN-L can be configured to work in Normal or Idle mode. In Normal mode, the input is monitored continuously and the output is activated if the voltage dips below the specified level. In Idle mode, the input is monitored only periodically, saving power when the voltage levels remain stable.

The SP708TEN-L is a versatile IC that is commonly used in embedded systems and in automotive applications. It is designed to monitor and detect voltages, as well as generate a reset signal when fault conditions occur. This makes it a great choice for systems that require stable power supplies and reliable reset operations.
