Power Management Integrated Circuits (PMICs) are the electronic components used to provide power and manage power-related functions for a variety of applications. PMICs can be broadly classified into two categories: Supervisors and Voltage Regulators. Supervisors are used to monitor inputs and system conditions, while voltage regulators are used to regulate output voltages and currents. The S-1003CA20I-I6T1U is a supervisor IC within the PMIC family, designed to govern and protect a system from undesired conditions such as power surges, excessive power consumption, or power reversals. In this article, we will discuss the application field and working principle of the S-1003CA20I-I6T1U.

The S-1003CA20I-I6T1U supervisor IC is a low power, low voltage 3.3V, 1.8V, and 1.2V supervisor with monitoring, reset, and Open Drain (OD) function. It is primarily used in consumer, automotive, industrial, and portable electronic applications. This IC is ideal for battery-powered applications, as it has a low quiescent current operation. Additionally, the S-1003CA20I-I6T1U features built-in precision voltage reference, adjustable voltage threshold and delay timing, making it suitable for voltages ranging from 1.5V to 5.5V.

The S-1003CA20I-I6T1U works by monitoring input voltage and activation time. When the device is turned on, it first measures the input voltage of the system. If the device is within the acceptable voltage range, then it will continue to the next step. The S-1003CA20I-I6T1U then monitors the activation time of the system. If the activation time is longer than the set threshold, the device will trigger the reset or open drain output. If the activation time is shorter than the set threshold, then the supervisor IC will continue its normal operation. The S-1003CA20I-I6T1U is also equipped with an over-voltage protection circuit, which will trip if the input voltage exceeds its voltage threshold.

In summary, the S-1003CA20I-I6T1U is a low power, low voltage supervisor IC designed for use in applications where power preservation and safety are crucial. It is suitable for applications such as consumer electronics, automotive, industrial, and portable electronics, as it offers adjustable voltage thresholds, low quiescent current operation, and over-voltage protection. The IC has a monitoring and reset feature, which monitors input voltage and activation time and triggers the reset or open drain outputs if the voltage or activation time exceeds the set thresholds.
