PMIC (Power Management Integrated Circuit) supervisors are devices that provide protection, diagnostic functions, and reset generation capabilities for system microcontrollers and digital logic. The Texas Instruments TPS389018DSET is a supervisor PMIC device that belongs to the TPS389 family of products, offering enhanced performance and reduced design complexity for a variety of system designs. This article explains the application field and working principle of the TPS389018DSET.

The TPS389018DSET is designed for use in a variety of systems, including microprocessors, application-specific integrated circuits (ASICs), memory, and peripheral logic. The device provides superior power sequencing and sequencing accuracy, allowing it to meet the power requirements of a wide range of applications. The device also features programmable features such as reset timing, polarity, and output current to enhance system stability. In addition, the device supports a configurable fault list, offering an integrated solution for system health monitoring.

The TPS389018DSET provides voltage monitoring and reset capabilities, with a high-accuracy voltage monitoring input wide-ranging from 2V-3.6V and an adjustable reset timeout. The device includes multiple supply pins, which can be used to supply system and auxiliary supplies. Graphics processors, digital audio, wireless transceivers, and other peripherals can be powered using the TPS389018DSET\'s supply pins.

The TPS389018DSET supports a wide-ranging power-down reset timeout and is endowed with robust watchdog and power-on reset (POR) capabilities. If a power failure is detected, the device will generate a reset signal and, if necessary, will also generate a watchdog timer reset. The device can detect short-term power drops, preventing unwanted system shut down, reset, and system reboot delays. In addition, the TPS389018DSET features protection against over-voltage, under-voltage, and over-current detection.

The working principle of the TPS389018DSET is fairly simple. The device functions by monitoring the system voltage and providing a reset pulse when the voltage falls outside a pre-defined range. When the voltage is too low, the device will issue a reset warning before generating a reset pulse. The device also supports an adjustable reset timeout, which allows for system boot-up and shutdown functions in specific time frames. The device includes an integrated watchdog timer and power-on reset (POR) circuit, offering system health monitoring and protection against unwanted system pauses.

In conclusion, the TPS389018DSET is a supervisory PMIC device used for power sequencing, precision voltage monitoring, and reset generation capabilities in system microcontrollers and digital logic. The device is designed for a variety of system designs, supporting wide-ranging power-down reset timeout, programmable features such as reset polarity and output current, protection against over-voltage, under-voltage, and over-current detection, and an integrated solution for system health monitoring. The device works by monitoring the system voltage and providing a reset pulse when the voltage falls outside a pre-defined range. The TPS389018DSET is an ideal solution for a variety of system designs.
