PMIC - Supervisors are integrated circuits that are designed to provide system-level management of applications that require advanced monitoring, protection, and reset control. The Texas Instruments TPS3852H33DRBR is a voltage supervisor IC which is optimized for providing safety management to a wide range of electronic systems.

TPS3852H33DRBR has a low quiescent current and offers precision reset control with a maximum accuracy of ± 0.7% of the nominal voltage. It features an integrated voltage-level detector adjustable over a wide operating range of up to 1.376 V with 0.01V increments. This voltage supervisor provides an external reset output which is activated when the user-defined threshold is not met, to protect the system against under voltage conditions. Furthermore, the TPS3852H33DRBR provides a wide selection of reset time delays, spanning from 8.2 ms up to 812 ms.

Moreover, the TPS3852H33DRBR provides multi-functional pins such as open-drain alarm output for reporting system events, active low brown-out voltage threshold setting, active low reset output and active low power-on-reset output. The power-good circuit is used to indicate the system\'s power and allows the most core elements of the system to initialize properly.

The TPS3852H33DRBR is suitable for a myriad of applications, ranging from automotive and aerospace to industrial control units. This voltage supervisor provides a complete solution for reset management in all types of real-time embedded systems. It is also used in medical and smart grid applications.

The TPS3852H33DRBR operates using two distinct modes: the low power mode, and the main supply monitor detection mode. Firstly, it continuously samples the input voltage supply to check whether it is above the user-defined trip point. If the power remains above the desired threshold, it enters the low power mode, where a low quiescent current of 5 microamps allows an extended battery life. If the input reaches below the trip point, the TPS3852H33DRBR will activate an external reset output. Moreover, the TPS3852H33DRBR protects the system from over voltage by keeping the reset and power-on reset outputs active when the voltage level exceed the desired limit.

In conclusion, the TPS3852H33DRBR voltage supervisor IC is a versatile and powerful solution for monitoring and protection of your application, and is suitable for a broad range of industries and applications. It is able to operate in both low power mode and main supply monitor detection mode, offering a complete reset management package with minimal power consumption.
