S-1003NB33I-M5T1U Application Field and Working Principle

The S-1003NB33I-M5T1U is designed to provide superior power supply monitoring, reset and protection for application fields such as automotive ECUs, industrial controllers, and consumer electronics. This device also integrates advanced protection features such as overload protection current limit and load store freeze for best-in-class reliability. The S-1003NB33I-M5T1U PMIC Supervisor is capable of monitoring a variety of different power supply voltages, and its advanced reset sequencing ensures safe and reliable operation in the event of system brownout or power supply failure.

The S-1003NB33I-M5T1U PMIC Supervisor is based on an advanced microcontroller which allows the device to accurately monitor system power and reset values. The supervisor can detect when the power supply drops below an adjustable threshold, or when the reset signal is deasserted. When these conditions occur, the supervisor sends a signal to reset the microcontroller. This reset signal is held high for a programmable amount of time before being deasserted. This delay time is adjustable allowing for fine tuning of the reset timing.

The S-1003NB33I-M5T1U offers a wide range of monitoring options, including adjustable trip points, windowed watchdogs, watchdog reset and manual reset. These features allow the supervisor to detect a wide variety of system faults, ensuring that the microcontroller is reset appropriately and in a timely manner for optimal system performance. In addition, the supervisor also offers integrated over voltage protection, brownout detection and watchdog timeout protection to ensure safe and reliable operation.

The S-1003NB33I-M5T1U PMIC Supervisor is a key component in providing reliable and robust system control, power sequencing and protection. It is ideal for high reliability applications such as automotive ECUs and industrial controllers, as well as applications requiring advanced power supply monitoring, reset and protection. The device offers superior power supply monitoring, reset and protection in a small footprint, making it an ideal solution for cost-sensitive embedded designs.
