S-1000C40-N4T1U Integrated Circuits (ICs)

PMIC - Supervisors are responsible for ensuring microelectronic stability in electronic systems. One of the more popular PMIC–Supervisor devices is the S-1000C40-N4T1U. This particular device is suitable for a variety of applications, from point-of-load dc/dc converters to complex systems with multiple power rails.

The S-1000C40-N4T1U is a fixed 5-volt supervisor with precise voltage monitoring and integrated reset circuitry. It can be used to monitor a single voltage, or it can be used to monitor multiple voltages in multiple power rails to ensure stability in advanced systems. The reset signal can be used to alert other components to the change in voltage. It is an efficient, reliable solution for an advanced power management system.

Application Field:

The S-1000C40-N4T1U is a highly versatile device. It can be used as a single voltage monitor as well as a multi-voltage monitor. It has wide range of applications such as power converter systems, point-of load DC/DC converters, computer systems, communication systems, storage system and handheld products.

It is designed for precision voltage monitoring for either single or multiple power rails. It is well suited for microprocessor-based systems that require precise voltage monitoring due to its high accuracy and fast response time. It is also used in automotive applications, where fault detection and system recovery is essential.

Working Principle:

The S-1000C40-N4T1U works by using a compare threshold that is set by an external resistor. This resistor is connected between E/S and GND pins. When the voltage on the E/S pin is lower than the pre-set threshold, the reset output pin is asserted. The reset output pin is then released when the voltage on the E/S pin is greater than the threshold.

The reset threshold voltage is preset, and the reset detection accuracy is independent of the supply voltage and is typically 0.1%. The device has a fast response time of typically 1.5ms, and the reset output can be used to alert other components to the change in voltage.

The S-1000C40-N4T1U is also equipped with a watchdog timer. This timer can be used to detect system malfunction and to reset the system if necessary. The watchdog timer is set by a capacitor on the WDT pin, and the device can be configured for either a window watchdog timer, or an interval watchdog timer.

The reset output is open-drain and is compatible with both CMOS and TTL logic levels. It is able to source and sink up to 20mA of current and has an operating temperature range of -40°C to +85°C.

Conclusion:

The S-1000C40-N4T1U is a highly versatile, efficient and reliable solution for a wide range of applications such as power converters, point-of load DC/DC converters and computer systems. It is designed for precise voltage monitoring for either single or multiple power rails, and its reset output can be used to alert other components to the change in voltage. Additionally, it is equipped with a watchdog timer for system malfunction detection and reset. Overall, the S-1000C40-N4T1U offers a powerful and reliable solution for ensuring system stability and reliability.
