IntroductionThe TPS3103H20DBVR is a sophisticated supervisor and protection device integrated into a single package with an integral circuit breaker. It is designed to provide protection against over-voltage, over-current, over-temperature and short-circuit protection. The integrated circuit breaker reduces the number of external components needed and can be adjusted to meet system’s current limit requirements. It provides a safe way to reduce on-board components required for power supply design.Application Field and Working PrincipleThe TPS3103H20DBVR is typically used in a variety of application fields, including automotive, aerospace and industrial automotive power systems.In automotive power systems, the TPS3103H20DBVR is used for over-voltage, over-current, over-temperature and short-circuit protections. It is also used for voltage monitoring and power on/off sequencing. The TPS3103H20DBVR has an integrated circuit breaker that can be adjusted to meet system’s current limit requirements.In aerospace power systems, the TPS3103H20DBVR is used to detect and protect against potential over-voltage, over-current, over-temperature and short-circuit conditions. The device also provides power on/off sequencing and fault reporting.In industrial power systems, the TPS3103H20DBVR is used to provide over-voltage, over-current, over-temperature and short-circuit protections. It is also used for power supply supervision and protection, as well as voltage monitoring. The integrated circuit breaker can be adjusted to meet system’s current limit requirements.The working principle of the TPS3103H20DBVR is based on a digital comparator and voltage monitor. The digital comparator compares the input voltage to the programmed threshold voltage. If the input voltage exceeds the threshold voltage, the comparator trips and the output turns off. The voltage monitor monitors and detects over-voltage and under-voltage conditions and provides a voltage flag output. The device is also equipped with an adjustable and integrated circuit breaker to reduce the number of external components needed. The circuit breaker features an adjustable current limit setting which can be used to set a maximum current limit for the system.ConclusionThe TPS3103H20DBVR is a supervisory and protection device that is used in a variety of application fields, including automotive, aerospace, and industrial power systems. It is designed to provide over-voltage, over-current, over-temperature and short-circuit protection and also provides power on/off sequencing, fault reporting, and voltage monitoring. The integrated circuit breaker can be adjusted to meet system’s current limit requirements. The TPS3103H20DBVR is an ideal device to provideprotection against potential over-voltage and over-current conditions.
