PMIC - Supervisors are integrated circuits designed to monitor system parameters like current, voltage, temperature, and over / under voltage conditions. The TPS3850G33QDRCRQ1 supervisor IC is an adjustable-threshold, fixed-delay output voltage monitor that detects over- and undervoltage conditions to provide protection for battery-powered circuitry. It accurately monitors and debounces signals from power sources, with a built-in push-button reset circuit and advanced low quiescent current and low-power modes.

The TPS3850G33QDRCRQ1 has a reset push button which can be used to reset the supervisor IC in the case of a power failure or an over- or undervoltage condition. It also has an adjustable voltage threshold and a fixed reset delay. The adjustable voltage threshold allows the user to set the desired threshold voltage and the reset delay ensures that the system will not be reset while the signals are within the set voltage range.

The TPS3850G33QDRCRQ1’s primary application field is in battery-powered systems, especially in portable and handheld applications. In these applications, the supervisor IC provides accurate voltage monitoring and reliable protection for the system. The chip’s low quiescent current and low-power features ensure that it is optimized for prolonged battery life.

The working principle of the TPS3850G33QDRCRQ1 is simple and straightforward. The supervisor IC constantly monitors its input voltage, and once the voltage exceeds the user-defined threshold, the chip triggers a reset or interrupts operation. The integrated reset push button can be used to reset the supervisor IC in the case of a power failure or an over- or undervoltage condition.

In summary, the TPS3850G33QDRCRQ1 supervisor IC is a vital component of battery-powered systems, especially in portable and handheld applications. It provides accurate voltage monitoring and reliable protection for the system, while its low quiescent current and low-power features ensure that it is optimized for prolonged battery life. Its working principle is simple and involves the continuous monitoring of input voltage and generation of a reset or interrupt once the voltage exceeds the user-defined threshold.
