The S-80135ANMC-JCUT2U is a device within the Power Management Integrated Circuit (PMIC) - Supervisors family. It is designed to help prevent accidental system reset and assist with safe power sequencing during system power-up and power-down operations. The S-80135ANMC-JCUT2U does this by setting up a soft reset. This reset occurs when the power-up voltage is equal to or greater than the preset threshold. When the voltage returns to normal, if the power-down voltage is lower or equal to the preset threshold, then the reset will remain active until the system is powered up again. Thus, the S-80135ANMC-JCUT2U safeguards against the accidental loss of data.

Due to its high reliability and sophisticated features, the S-80135ANMC-JCUT2U is extremely suitable for harsh conditions such as those found in automotive and industrial applications. Adding to its versatility, the device can be used with a wide range of SCRs and MOSFETs. In addition, the device has very low quiescent current which helps to ensure sustained system power.

The S-80135ANMC-JCUT2U has a wide operating temperature range and a low power-up/down voltage threshold of 0.4 V. Overvoltage and foldback protection is provided to keep the output from rising too high. Flexible input capability allows the device to be connected with various types of supplies from external sources and the low intensity SEL output helps ensure that you are fully in control of your power sequencing operations even during the most challenging conditions.

The operation of the S-80135ANMC-JCUT2U is based on a low voltage-threshold method. Its built-in adjustable voltage comparator monitors the power supply voltage. When the supply voltage crosses the threshold, it activates the soft reset signal and the outputting pin (SEL#) is forced low. This low-active SEL# output is fed back to the system, causing the soft reset. When the voltage recedes below the preset threshold, the SEL# output will return to its original high state, allowing the system to continue from its last state without any data loss.

In addition to its reset function, the S-80135ANMC-JCUT2U can be configured for power management in certain applications. With its low-impedance drive output, the device can directly drive external loads such as relays, SCRs and MOSFETs. This makes it suitable for not only soft reset applications, but also for power sequencing operations during system power-up, power-down and fault reporting.

The S-80135ANMC-JCUT2U also features an open drain option which allows the internal reset elements to be paralleled with external reset elements. This eliminates the need for extra external components and provides a more flexible low-voltage reset solution. Furthermore, the device includes both manual and automatic reset modes, allowing further flexibility in power sequencing applications.

The S-80135ANMC-JCUT2U is a versatile and sophisticated device that can provide excellent protection against system-induced resets and power sequencing events. It has a wide operating temperature range and can be used with a wide variety of external loads such as SCRs and MOSFETs. It also has low-impedance outputs, low quiescent current, overvoltage and foldback protection, and both manual and automatic reset modes which make it a great choice for harsh automotive and industrial applications.
