Introduction

ADM809JARTZ-REEL7 is a component coming from the ADM809JARTZ series of supervisors that has become a trusted component in the electronics industry. It is a Polymeric Positive Temperature Coefficient (PPTC) Resettable fuse and belongs to a set of integrated system-level solutions from ADM809JARTZ. It is classified as a PMIC - Supervisors component and has several applications.

Application Field

ADM809JARTZ-REEL7 is widely used in a variety of systems from industrial, automotive to medical applications. In Industrial applications, it is used for system level monitoring as it provides +/- 20V operating voltage and 2A peak current (max) for its trigger input pins. It is widely used for fault protection due to its fast response time and high accuracy. In automotive applications, it is used for internal circuit protection, especially for low voltage regulators and automotive-grade logic ICs. In medical applications, it is used to monitor and provide fault protection of equipment. In addition, the component is also widely used in the electronics industry as a prototyping component.

Working Principle

ADM809JARTZ-REEL7’s working principle is based on the PPTC technology. It consists of two components, a temperature sensitive fuse (TSF) and a PTC resistor that works together to initiate a self-resetting action in case of a fault. When the device is in normal operation, the current flows through the TSF and the PTC is in an OFF state. In the event of an overcurrent, the PTC will start to heat up and resistance increases, resulting in a current-limiting action, allowing the TSF to gradually absorb additional heat. In case of a fault, the TSF will trip, causing the current to be cut off, which will reset PTC, allowing the circuit to reset after the fault has been removed. The device will then return to its normal operating state.

Conclusion

In conclusion, ADM809JARTZ-REEL7 is a PMIC- Supervisors component widely used in a variety of systems such as industrial, automotive, and medical applications. It works using the PPTC technology, which involves a temperature sensitive fuse and a PTC resistor that work together to initiate a self-resetting action in case of a fault. The device is highly reliable and provides fast response time and high accuracy, making it an ideal choice for system level monitoring and fault protection.
