PMIC - Supervisors: S-1003CA48I-I6T1U Application Field and Working Principle

PMICs, or power management integrated circuits, are a type of semiconductor device used in computers and other electronic devices to control voltage. PMICs are typically found in mobile phones, laptops, tablets, and embedded systems and are used to regulate power consumption and optimize efficiency and battery life. As such, they are a vital component in maintaining the optimal performance of electronic devices.The S-1003CA48I-I6T1U is a low voltage system supervisor IC. It provides a low power, low cost and extremely versatile solution to monitor the power state and detect the operating voltage of a system. It is designed to meet GOST 22210-2008 and IEC 60730-2-6 standards, providing a reliable, cost-effective and secure power supervisor for various applications.The S-1003CA48I-I6T1U is a compact, low cost, ultra-low-power system supervisor for 3.3V and 5V applications, such as embedded and computing systems. It has an integrated reset, low voltage detection, and clock signal output signal. It can detect two thresholds for input voltage. The low voltage reset signal is set with two external resistors to give sufficient headroom to ensure system stability.The S-1003CA48I-I6T1U is suitable for a wide range of embedded and computing applications, such as hand-held radios, industrial applications, robotics, automated testing and instrumentation. It is also suitable for harsh environments, such as airborne, marine and extreme temperature applications.The S-1003CA48I-I6T1U is designed to detect and react to abnormal or undervoltage conditions, quickly pulling a reset signal low to isolate the ailing device. This prevents corrupted data and related operations, thus promoting reliable operation and performance of the system. It also can detect low battery conditions in portable applications, automatically triggering appropriate action to prolong device life.The S-1003CA48I-I6T1U provides different services such as calling out the cold boot sequence and responding to the power on reset (POR) window extension. During normal system operation, it maintains 5 V hot management by initiating low reset during power fail situations. It also provides low power dissipation, with a quiescent current of just 20nA and typical power dissipation of 6.9μW/°C.The working principle of the S-1003CA48I-I6T1U is based on the comparison between an internal reference voltage and the power supply voltage. When the input supply voltage drops below the specified level, the output reset signal will be pulled low, thus resetting any modules that are connected to its output. It is triggered by a change in the level of the input voltage, either by increasing or decreasing it.In summary, the S-1003CA48I-I6T1U is a highly efficient, low cost and low power system supervisor IC. It provides accurate voltage detecting and resetting operations, offering reliable and stable power performance for a variety of applications. It is suitable for harsh environments, efficiently allowing devices to improve power management. Finally, it is an ideal choice for battery-operated systems, offering an easy-to-setup reset system and extended battery life.
