Power Management Integrated Circuit (PMIC) supervisory products are designed to protect microprocessors and other integrated circuits (ICs) when they are subject to unexpected power losses. The S-1003CB12I-I6T1U is an example of one of these products.

The S-1003CB12I-I6T1U is a low-power supervisor IC that is capable of providing power protection to low power applications. It is well suited for portable consumer electronic products, such as mobile phones and portable media players, that operate with battery power. It can also provide power protection for embedded applications, such as IoT (Internet of Things) devices.

The S-1003CB12I-I6T1U is a voltage supervisor IC with a watchdog timer. It contains a wide-input voltage range sensing circuit that monitors a system’s operating voltage and sends an interrupt signal when the operating voltage falls below the minimum level. The reset pins can control a low side switch which is used to reset the system when a low power signal is detected.

The S-1003CB12I-I6T1U provides robust power protection which minimizes the impact of power supply interruptions and eliminates the need for external components such as voltage regulator, voltage supervisor and reset circuits. It can be used as a combined protection device for low power applications, where a single IC provides both power monitoring and reset functions.

The S-1003CB12I-I6T1U is also designed to operate in either standalone or wired-AND architecture. In the wired-AND architecture, two or more S-1003CB12I-I6T1U ICs can be connected in series to provide multiple power-down protection in case of single power supply failure. The advantage of using the wired AND architecture is that it provides protection against any single point failure in the system.

The S-1003CB12I-I6T1U watchdog timer is a feature which enables the supervisor to provide additional safety to system operations. If a system fault is detected which causes unexpected power losses, the watchdog timer will trigger an active reset signal to the system, which thereby preventing system damage. The watchdog timer also features a slow discharge to ensure a safe reset even under low-power conditions.

The S-1003CB12I-I6T1U is available in three package types, TO-92 for bulk applications, TO-252 for surface mount applications, and TSSOP-8 for surface mount applications with tight board spacing.

Overall, the S-1003CB12I-I6T1U is a low-power supervisor IC that provides power protection and reset functions for a wide range of applications. With its wide input voltage range sensing circuit, active reset signal and watchdog timer, the supervisor is ideal for applications that require robust power protection. The small package size and low power consumption also make it suitable for embedded and portable applications.
