The S-1003CA26I-I6T1U is a microprocessor supervisory circuit designed for applications requiring extremely low power consumption. It is a single-supply power management integrated circuit (PMIC) with an on-board battery switch that connects external pins to the ground during power failure or deep sleep modes. This ensures uninterrupted operation even in the event of power failure. The S-1003CA26I-I6T1U is used in portable and notebook computers to monitor power and voltage status, prevent under-voltage, over-voltage, over-current, and over-temperature conditions, and alert the system to dangerous power conditions.

The S-1003CA26I-I6T1U is an advanced low-power PMIC supervisor designed to support low-voltage, low-power applications. It features one 5-V output and two 3.3-V outputs, both with adjustable voltage regulation. It also provides protection against over-voltage, over-current, over-temperature and short-circuit conditions. The supervisor offers selectable threshold levels for under-voltage, critically low-voltage, and over-voltage conditions to provide warning or proactive power system shutdown whenever power conditions exceed the user-defined thresholds.

The S-1003CA26I-I6T1U also includes an integrated battery switch that can be used to detect power failure or deep sleep events and safely shut-off the system. It includes a built-in watchdog timer to ensure proper system operation and to detect errors, hangs, or system freezes. It also features a timeout window during which the presence of a watchdog timeout assertion cannot be recognized. The supervisor’s brown-out detection feature helps to protect against brown-outs, offering preemptive shutdown in the event of a voltage drop.

The S-1003CA26I-I6T1U offers low operating current, low quiescent current, and low power-on reset timing for improved efficiency and system performance. It also has an integrated battery switch that can be used to switch an external power source from high to low voltages and vice versa. The versatile supervisor offers comprehensive voltage, temperature, and current monitoring to protect against over-voltage, under-voltage, over-temperature, and over-current conditions.

The S-1003CA26I-I6T1U is ideal for applications in portable and notebook computers where low power consumption is a priority. It offers a broad range of protection features and can be used in both hard power and soft power applications. Its wide input voltage range and low operating current provide long life and reliable operation. It is a reliable and economical solution for the monitoring and control of power systems.
