S-80924CNMC-G8UT2G application field and working principle

S-80924CNMC-G8UT2G is a robust supervisor with system reset pulse and power good signal that is ideal for battery- operated and back-up applications. It features an adjustable reset threshold voltage, low operating current, and is available in the industry standard 8-pin SOIC package. With the low operating current and adjustable reset, S-80924CNMC-G8UT2G provides improved protection and increased accuracy to many battery powered products. Additionally, the device is width tolerant, meaning it can adapt to a wide range of input supply voltages, limiting the need for precise programming and external components.

This device can help protect against brown-outs or transients, preventing unreliable operation due to voltage drops or voltage spikes. S-80924CNMC-G8UT2G monitors the input supply voltage from a wide range of 3V to 36V and provides a reset signal when it falls to an adjustable threshold voltage. The reset signal can then trigger a shutdown of the system and/or the reset of the microprocessor. The device also has an active low power good signal that can be used as an indicator for the system to determine when the power is stable and the system is ready to start.

The S-80924CNMC-G8UT2G is designed to provide a high, accurate threshold voltage accuracy without relying on external components. The reset threshold voltage is internally adjustable (VTH) and can be adjusted to the ideal voltage level by varying resistance. Also, because the device operates with only 13µA (typical) of bias current, it can be used in energy-sensitive applications and battery operated devices where power is a major consideration.

In terms of reliability, the S-80924CNMC-G8UT2G is designed to withstand surges up to 30V and can operate in temperatures ranging from -40°C to +85°C, providing a high degree of protection against environmental factors. Additionally, the device is also certified to meet with automotive, aviation and industrial standards for reliability, providing extra assurance for demanding applications.

The S-80924CNMC-G8UT2G is an excellent choice for a wide range of system power management applications. Whether used in a battery-operated device, industrial equipment, automobiles, or aircrafts, this device can provide the robust protection needed for reliable system power management in any situation.
