PMIC - Supervisors: S-80154ANMC-JDFT2G Application Field and Working Principle

The S-80154ANMC-JDFT2G is a high-end supervisory integrated circuit (IC) within the Supervisors family of PMIC (Power Management Integrated Circuit) devices. It is primarily used as a robust reset and monitoring system in various equipment and devices used in avionics and industrial control systems. This powerful IC integrates a variety of electronics functions and advanced protection technologies needed for digital power system design in order to resist parametric shifts and/or environmental shocks.

The integrated circuit’s functioning is divided into two distinct modules: the core circuitry and the voltage supervisor portion. The core module is composed by the reset logic and analog control circuits, plus the programmable monitoring logic of the IC. This portion of the circuitry is responsible for controlling the system’s reset logic, monitoring the voltage levels and providing necessary fault flags and generation of system reset signals.

The voltage supervisor portion of the S-80154ANMC-JDFT2G is responsible for supervising an auxiliary voltage. The voltage will then be compared against internal reference thresholds, where the thresholds are fixed or programmed by the user. Thresholds can be programmed and configured to provide the user with high flexibility of reset and monitoring system. Adjusting the thresholds allows for user optimization, making the S-80154ANMC-JDFT2G a versatile and highly reliable device.

Features

• Monitors up to 5 independent power supplies at once
• Adjustable reset thresholds
• Programmable reset cycle times
• Fault detection logic
• Independent monitoring, reset, manual reset and watch dog outputs
• Wide input supply range
• Very small overall size (2.2 x 2.2 mm package)

Applications

The S-80154ANMC-JDFT2G Supervisors IC is widely applicable for various avionics systems, industrial control systems, automotive system and instrumentation laboratory equipment. Its features make it suitable for monitoring and resetting systems in these environments, ensuring that faulty and unstable operations are kept in check for the sake of security and reliability.

Working principle

The S-80154ANMC-JDFT2G circuit functions by monitoring the voltage levels of various power supplies. When the voltage levels are found to be out of tolerance, the reset logic is activated, forcing the circuit to reset. Furthermore, if the reset is not done within a certain cycle time, the fault flag is activated and a reset signal is sent to the system to force reset. The supervisor portion of the circuit also monitors and compares the voltage levels of an auxiliary power supply to preset and programmable thresholds, providing users with added sensor functionality.

The S-80154ANMC-JDFT2G is a reliable, highly efficient IC that ensures the reset mechanisms of power systems remain functional and in safe operating conditions. The robust reset logic, adjustable cycle times, fault detection and adjustable reset thresholds provide users with great flexibility when it comes to monitoring and resetting systems. This IC is highly popular among avionic and industrial control systems for its multi monitoring and reset capabilities, small size and robust design.
