The S-80126BLPF-JELTFU PMIC supervisor is suitable for a wide range of applications, including mobile devices, telecommunications equipment, automotive electronics, medical devices, and more. Its multi-voltage feature makes it especially suitable for mobile applications, such as 5V and 3.3V, as well as sub-1V rail systems. The device\'s wide operating temperature range from -40°C to 85°C makes it suitable for a variety of environments, from low-temperature automotive applications to high-temperature industrial equipment.

The S-80126BLPF-JELTFU device is designed to provide a complete system supplant safety solution. It offers an advanced reset programmable level detection and filtering, overvoltage and undervoltage protection, as well as a soft-start and control power sequencing mechanisms. This device also has an integrated reset generator and an adjustable reset timer, making it ideal for applications with complex sequencing requirements.

Working Principle

The S-80126BLPF-JELTFU PMIC supervisor is based on a 2-channel reset signal detection and timer circuit. It has an internal comparator which monitors the status of the signal, and if it detects a low-voltage or overvoltage condition, it will activate a reset sequence. The device also utilizes an advanced signal filtering technique to reduce false trigger rates and improve noise immunity. The reset timing can be adjusted via an external capacitor, to provide an accurate reset timing for various applications.

In addition, this device also offers advanced reset latencies for both the power-on and power-off sequences. The power-on latency is adjustable from 4ms to 1s, and the power-off latency from 4ms to 5s. This feature helps to ensure the fast and accurate voltage stabilization after the transition from power down to power up. In addition to this, the device also has a robust protective circuit with built-in fault detection circuitry, which allows it to quickly detect and protect against power-related fault events.

The S-80126BLPF-JELTFU PMIC supervisor can be used as a standalone solution for managing power supply sequencing, or it can be integrated with other safety and fault-protected functions, such as an EMI/EMC filter, linear regulator, and dropout regulator to create a comprehensive system-level protection solution.
