TPS3803-01QDCKRQ1

PMIC - Supervisors are electronic devices used to prevent unstable voltage and system damage as a result of an over or under voltage. The TPS3803-01QDCKRQ1 is a simple, cost effective supervisor IC that monitors one or two supply rails and can be used to prevent power system damage.

The TPS3803-01QDCKRQ1 supervisor circuit offers a few features of note. It has undervoltage lockout (UVLO) and brown-out protection, voltage tracking, and manual reset capability. It also features a single power-up delay and fault/resume detection configuration. The supervisor circuit is designed for automotive, industrial and consumer applications and is able to provide a temporal power-off signal and reset pulse.

As for the TPS3803-01QDCKRQ1 application field, it can be used in a variety of applications including power supplies and industrial systems such as factory automation and process control. It is also useful for protecting energy harvesting and management systems, battery-backed systems, and hot-swap designs.

The working principle of the TPS3803-01QDCKRQ1 is fairly simple. The device monitors one or two supply rails using an on-board comparator. When the voltage drops too low, it will reset the system as it is programmed to do. By setting the voltage trip point, the supervisor can be used to automatically shut off power systems when the voltage threshold is reached. This prevents the system from overloading, damaging the components, and potentially causing fires.

The power-up delay feature of the TPS3803-01QDCKRQ1 will keep the system from being reset during power up. This is important so that the system can be initialized properly before it is powered on. The fault/resume detection configuration will detect any voltage abnormalities and will reset if necessary. This feature also prevents overloading by immediately shutting off power in the event of too high of a voltage spike.

The TPS3803-01QDCKRQ1 supervisor IC is a cost effective device that can be used in a variety of applications. It is able to protect a power system by resetting or cutting power when a voltage abnormality is detected. With its wide variety of features, it is suitable for a range of applications and will help keep your system safe from damage.
