S-1003CA35I-I6T1U

Power management integrated circuits (PMICs) are widely used in the design of electronic devices, especially those with an embedded microcontroller, for the purpose of providing regulated voltage and power to different components of the system. A supervisor is a particular type of PMIC designed to monitor battery voltage and system reset functions.

The S-1003CA35I-I6T1U is a high precision analog supervisor for embedded microcontroller systems. It offers a high degree of accuracy and flexibility through its wide operating temperature range and low power consumption. It is available in space-saving PQFN-8 and WFBGA-10 packages, and provides an ideal solution for applications that require accurate, long-term monitoring of battery voltage.

Application Field

The S-1003CA35I-I6T1U is often used in industrial, medical, automotive and communications applications that require a long-term, accurate monitoring of battery voltage. It is suitable for monitoring the voltage of battery systems up to 36V, and is capable of withstanding extreme temperature conditions. It is also suitable for applications that require robust system reset functions, such as controlling power-up and power-down sequences in embedded systems.

Working Principle

The S-1003CA35I-I6T1U is a high-precision analog supervisor with a wide operating temperature range and low power consumption. It works by continuously monitoring battery voltage with an operating voltage range between 0.8V and 36V. It features an on-chip comparator that compares the monitor voltage with an adjustable pre-programmed threshold. When the monitor voltage reaches the threshold level, the device generates an active-low reset signal that can be used to control the system power-up and power-down sequences.

The device also incorporates a low-battery detector that is used to detect battery depletion and issue a warning signal. The detection voltage level can be adjusted in the range from 0.6V to 0.9V. The S-1003CA35I-I6T1U can also detect overvoltage conditions, allowing for safe system operation. It is designed for low-power applications and its power consumption is very low, making it suitable for low-energy designs.

In summary, the S-1003CA35I-I6T1U is an ideal solution for applications that require monitoring of battery voltage and reset functions. It offers a wide operating temperature range, low power consumption and high precision analog supervisor capabilities, making it suitable for a wide range of applications.
