PMIC - Supervisors commonly refer to integrated circuits that provide various system voltage monitoring and supervision functions. Designed to provide safe, flexible, reliable system management, the TPS3852G33DRBR is a high-sensitivity voltage supervisor with an active-low reset output. It continuously monitors the system power supply voltage and generates a reset signal when the voltage drops below the preset threshold. In addition, the reset signal is generated based on the detection of RESET/NMI input. This device can also be used to generate a manual reset pulse on demand.

The TPS3852G33DRBR offers an adjustable reset threshold ranging from 1.08V to 2.40V. It is designed to monitor a single supply voltage in both reset assertion and de-assertion steps. The adjustable reset time-delay lets the user select the delay needed to independently modify the reset output pulse width depending on the external capacitor used. This device also has an integrated counter circuit that measures the time duration before reset active.

This supervisor can implement a tight power-on reset in microcontroller-based systems. It offers an excellent delay accuracy with voltage reset hysteresis. With its wide temperature range, the device can be used in various applications including AdvancedTCA, MicroTCA, servers, industrial PCs, and embedded logic.

The TPS3852G33DRBR has a very simple working principle. It continuously measures the supply voltage and if the voltage falls below the preset threshold, a power reset signal is generated. To prevent frequent False-ONs, it is designed to avoid accidental initiation due to momentary spikes in the measured voltage. For example, if the measured voltage drops below the preset threshold but rises back before the reset signal is activated, the device will reset, but only after a delay period.

Another important function of the TPS3852G33DRBR is its manual reset feature. This feature offers a manual reset signal to a microcontroller or other logic by applying RESET/NMI input. This signal can also be used to generate a manual reset pulse on demand.

In summary, the TPS3852G33DRBR is a high-sensitivity voltage supervisor ideal for ensuring safe and reliable system management in microcontroller-based systems. It offers an adjustable reset threshold, active-low reset output, adjustable reset time-delay, integrated counter circuit and offers excellent delay accuracy with voltage reset hysteresis. It is widely used in AdvancedTCA, MicroTCA, servers, industrial PCs and embedded logic.
