Power management ICs (PMICs) are a type of integrated circuit (IC) used to manage a variety of power related functions. Supervisors are a type of PMIC specifically designed to prevent system malfunctions by monitoring various system parameters. The S-1003CA21I-I6T1U is a supervisor IC specifically designed for microcontroller-based systems that require a low pin count and 400 kHz I2C interface. In this article, we’ll discuss the application field and working principle of the S-1003CA21I-I6T1U.

The S-1003CA21I-I6T1U is designed for microcontroller-based systems that require an external supervisor IC, such as telecom base station controllers, industrial control systems, and automotive systems. It is a low power, low pin count supervisor IC that is capable of monitoring up to three power supplies. The IC is designed for monitoring SIM card power supplies, as well as +3.3 V and +5 V device power supplies. It is also capable of providing a reset output for the system microcontroller. The S-1003CA21I-I6T1U is designed to provide high accuracy and extremely low power consumption.

The S-1003CA21I-I6T1U is a three-channel power manager IC that can monitor up to three power supply levels. The IC can be configured to detect various trip points or thresholds, such as undervoltage (UV) threshold, overvoltage (OV) threshold, and undercurrent (UC) threshold. The IC can also be configured to generate a reset output and an interrupt output when the monitored power supply level exceeds the threshold. The user can customize the various voltage and current thresholds, thus allowing the IC to monitor a wide range of power supply levels.

The S-1003CA21I-I6T1U is also equipped with an I2C interface for communication. The I2C interface operates at a maximum speed of 400 kHz, allowing the IC to communicate with compatible microcontrollers over the same bus. The IC is also capable of providing status information to the user via the I2C interface, including voltage and current measurements from the power supplies, as well as reset and interrupt information. In addition, the S-1003CA21I-I6T1U can be programmed to reset the system microcontroller when the power supply voltage falls below or exceeds the pre-programmed threshold.

The S-1003CA21I-I6T1U is a low power supervisor IC that can be used to monitor a wide range of power supplies. The IC is designed to provide a reset output, an interrupt output, and status information to the user, allowing for improved system performance and reliability. The S-1003CA21I-I6T1U can be used in microcontroller-based systems such as telecom base station controllers, industrial control systems, and automotive systems, as well as in other applications that require a low pin count and 400 kHz I2C interface.
