Power management integrated circuits (PMICs) are small, low-cost integrated circuits that provide a broad range of power management capabilities. PMICs are typically used in applications such as automotive, medical and consumer electronics. One such PMIC, the S-1003CA18I-I6T1U, is a supervisor IC designed to monitor power supplies for exceptional conditions such as overvoltage and undervoltage, and to assert a reset signal when a power supply exceeds specified limits. This article will discuss the application field and working principle of the S-1003CA18I-I6T1U.

Application Field

The S-1003CA18I-I6T1U is a voltage supervisor IC suitable for various systems and applications, including automotive electronics, consumer electronics, and medical systems. This IC is intended for applications that require monitoring of voltage levels and power issues, such as brownout detection and overvoltage protection. It is also suitable for multiple output operation in automotive electronics and consumer electronics systems.

The S-1003CA18I-I6T1U has a wide operating temperature range of -40°C to +125°C, making it suitable for use in automotive and consumer electronics applications. It also has a wide input voltage range of 2.2V to 3.6V and output voltage range of 0.9V to 5.5V, making it suitable for powering various electronic components. The S-1003CA18I-I6T1U also has a wide variety of protection functions including overvoltage protection, undervoltage protection, and overcurrent protection.

Working Principle

The S-1003CA18I-I6T1U is a supervisor IC designed to monitor power supplies for exceptional conditions such as overvoltage and undervoltage, and to assert a reset signal when a power supply exceeds specified limits. It can monitor two power supplies, one at VDD and the other at VDD_IO. The S-1003CA18I-I6T1U can also be used to detect overcurrent in automotive applications.

The S-1003CA18I-I6T1U is capable of monitoring multiple input and output voltages, and can assert a reset signal when either one exceeds the specified limit. When the voltage outside the specified limits is detected, the reset signal is asserted until the power supply is reset and the voltage is back within limits. The reset signal can be used to reset microcontrollers, FPGAs, and other system components.

The S-1003CA18I-I6T1U has two outputs that can be used to drive an indicator, such as a LED to indicate the power supply status. The S-1003CA18I-I6T1U also has an internal 0.8V reference circuit and has an adjustable detection voltage range. The detection voltage range is adjustable via an external resistor. The S-1003CA18I-I6T1U also has an adjustable output voltage range and can be used to provide power to other system components.

Conclusion

The S-1003CA18I-I6T1U is a PMIC – Supervisors that can be used for various power management applications such as automotive, medical, and consumer electronics.
