The S-1000C22-N4T1U is an advanced power management integrated circuit (PMIC) specifically designed for supervisory purposes. It offers an array of features that make it a versatile and reliable system for a variety of applications. It includes an adjustable voltage monitor with a selectable trip sensitivity and a range of thresholds for power fail, supply fail, reset and manual reset signals.

In addition to its robust monitoring capabilities, the S-1000C22-N4T1U also contains four independent, programmable power-gating FETs with adjustable hysteresis. This feature allows for a current-controlled shutdown of any circuits on the board while keeping other sections running. The programmable hysteresis value ensures that the ports will stay safely on or off. The S-1000C22-N4T1U also comes with an integrated low dropout regulator (LDO) capable of driving loads up to 120mA.

The S-1000C22-N4T1U is ideal for applications requiring a wide range of power/voltage monitoring capabilities, such as digital telecommunication systems, computer systems, and automated process control systems. It is also used to protect sensitive circuits against power supply transients or voltage irregularities. The S-1000C22-N4T1U can also be used for low power design, power supply sequencing, and power-up/power-down sequencing.

The S-1000C22-N4T1U works by monitoring and controlling the system’s power rails and various parameters such as voltage, current, temperature, and voltage-rail oscillations detected by the embedded comparators. When an undesired voltage or current level is hit, the S-1000C22-N4T1U can issue an alarm via a push-pull output or an open-drain output. It can also provide a manual reset signal or issue a power-on reset signal.

Moreover, the S-1000C22-N4T1U also provides an adjustable reset timeout output and an adjustable reset delay input. The reset timeout output, when enabled, will automatically reset the system when a certain amount of time has elapsed from the initial power-up. The reset delay input, when enabled, ensures that the reset signal is delayed by a certain amount of time to allow the system to complete its initialization before being reset.

The S-1000C22-N4T1U offers a more reliable and comprehensive monitoring and control system than conventional transistors-only circuits. With its adjustable threshold comparators, programmable FETs, and integrated LDO, the S-1000C22-N4T1U is a powerful and versatile supervisor circuit for a variety of applications. Plus, its compact, compact 6x6mm QFN package can fit into tight spaces and allows for better heat dissipation. So, the S-1000C22-N4T1U is the perfect choice for those looking for a reliable and power saving PMIC.
