PMIC (Power Management Integrated Circuit) supervisors are the building blocks of any power system. Their functions are simple, yet crucial to any system’s operation. The S-80955CLPF-G7RTFG is a type of PMIC supervisor that plays an important role in the proper operation of a system.

The S-80955CLPF-G7RTFG is designed to monitor, detect and respond to system power events. This PMIC supervisor features 4 dedicated reset pins and an active-low Reset Output, with three additional power supply sense pins to protect against undervoltage. It also has an internal watchdog timer and an adjustable delay after power-on reset (POR) for power-up sequencing and fault protection.

In addition to its standard functions, the S-80955CLPF-G7RTFG also has unique features such as programmable start-up timers, reset control inputs, UVLO and Brown-Out Reset, Adjustable Voltage Reference (AVREf) for monitoring voltage levels, and internal stepping logic to manage complex power-up sequencing. These features allow the S-80955CLPF-G7RTFG to provide system-level reset management and sequencing as well as complete power monitoring.

The S-80955CLPF-G7RTFG is typically used in applications where precise control of power-up sequence and system stability must be maintained. This is especially important in embedded systems, where multiple components must be powered up at precise voltages and times to ensure proper system operation. The supervisor also supports a wide variety of input voltage ranges, including 0.9V to 5.5V, and is compatible with multiple operating temperatures from -40°C to 85°C.

The S-80955CLPF-G7RTFG’s working principle is relatively simple. When power is initially turned on to the system, the supervisor initiates its start-up timer and configurable delay after POR circuit. This sequence allows for a precise power-up sequence for all components connected to the supervisor. In addition, the supervisor’s voltage reference, watchdog timer, and reset pins provide protection against power-supply irregularities.

Once the power up sequence is completed, the supervisor stabilizes the power rail and monitors power supply levels while keeping the system active. This allows the connected components to operate at precise voltages, as well as providing a source of early detection of power failure. The voltage reference, watchdog timer, and reset pins also ensure that components remain within their designated operation thresholds.

In summary, the S-80955CLPF-G7RTFG is an advanced PMIC supervisor that is designed to provide precise power-up sequencing and system stability in embedded systems. It features a programmable start-up timer, reset control inputs, adjustable voltage reference, and internal stepping logic to manage complex power-up sequencing. In addition, other features such as the watchdog timer and reset pins provide system-level fault protection. As a result, the S-80955CLPF-G7RTFG is an ideal fit for applications in which precise control of power-up sequence and system stability must be maintained.
