PMIC - Supervisors are devices that monitor the performance of a variety of applications and the overall system power to ensure a safe and efficient operation. The S-1000C39-I4T1U is a PMIC - Supervisors developed by EverRich, which offers some unique features unparalleled by other similar products. In this paper, we will focus on the application field and working principle of the S-1000C39-I4T1U.

Application Field

The S-1000C39-I4T1U was designed for use in industrial, automotive and other harsh environments. It is designed to monitor the power performance of a variety of applications and systems, such as fuel regulators, engine controllers and solenoids. It is also used in medical equipment and communication systems, where reliable power supply is essential. The device has wide temperature range capabilities, enabling it to work in both cold and hot conditions.

The S-1000C39-I4T1U offers a 6-15V input operating voltage range and maximum frequencies up to 12MHz. It features output shutdown, adjustable overcurrent and overvoltage protection, as well as an adjustable input voltage prescaler. Additionally, it offers a watchdog timer, EPWM outputs and low-dropout (LDO) regulators, all of which can be controlled via a two-wire high-speed serial interface.

Working Principle

The S-1000C39-I4T1U is based on a Self-Oscillating Precision Voltage Regulator (SPVR) topology. This topology enables the device to regulate voltage and current across a wide range of operating conditions. The SPVR uses a high-gain error amplifier to detect and compensate for any variations in input voltage, ensuring a stable and reliable undervoltage and overvoltage protection.

The S-1000C39-I4T1U also offers active monitoring and protection features that ensure safe system operation. To ensure such protection, the device features a supervised Watchdog Timer (WD), which is able to reset the system if it fails to meet certain criteria. Additionally, the device is equipped with overcurrent, ground fault, and overvoltage protection that continuously monitors these values and shuts down the system if they exceed the predetermined thresholds.

Moreover, the S-1000C39-I4T1U offers flexible control of system operational parameters such as EPWM outputs, soft start, power-up/down sequencing, and clock synchronization. These features can be adjusted through a two-wire high-speed serial interface, allowing for accurate monitoring and control of system power.

In conclusion, the S-1000C39-I4T1U is a highly reliable PMIC - Supervisors developed by EverRich that offers a wide range of features. It provides accurate monitoring and protection of applications and systems in a variety of fields, such as automotive and medical, with a high degree of flexibility. The device’s workings are based on SPVR topology, which ensures safe and efficient motor operation for a wide range of applications.
