TPS3850G12QDRCRQ1

PMIC (Power Management Integrated Circuit) is a device that efficiently manages power consumption in various applications. It combines a variety of distinct functions that are usually found in separate ICs, such as voltage regulation, isolation, current measurement, temperature protection and more. Supervisors, as a type of PMIC, mainly provide power-on reset for digital systems and address/data line protection for microprocessors. Among them, TPS3850G12QDRCRQ1 Supervisors from Texas Instrument are designed for monitoring system power supply, providing 4kV ESD protection for VDD and VSS, and providing power-on reset for digital systems.

It utilizes an on-chip voltage reference, comparator, and logic circuitry to monitor the power supply, providing power-on reset when the voltage reaches the reset threshold. The reset threshold is programmable with an external resistor (from 2.05V to 5.5V). The TPS3850G12QDRCRQ1 also features an open-drain reset output, enabling direct connection to the reset input of most microcontrollers and procesors. This makes the supervisor compatible with any microcontroller that requires a power-on reset or power-fail warning.

The TPS3850G12QDRCRQ1 Supervisors also feature an adjustable reset pulse timeout circuit, allowing for programmable reset pulse widths. When the supervised VDD falls below the reset threshold (VTRIP), the reset output is remain inactive for the specified reset timeout period. This ensures that the microcontroller is not affected by glitches or invalid power conditions. The application fields for the TPS3850G12QDRCRQ1 Supervisors are generally embedded systems, supervisory control and data acquisition (SCADA) systems, and industrial systems.

TPS3850G12QDRCRQ1 Supervisors are easy to use and require minimal external components. They feature an on-chip voltage reference, comparator and logic circuitry to monitor the power supply, providing power-on reset when the voltage reaches the reset threshold. Their open-drain reset output is suitable for direct connections to the majority of microcontrollers and processors, making the TPS3850G12QDRCRQ1 an ideal choice for applications that require a quick and easy power-on reset or a power-fail warning signal.

The TPS3850G12QDRCRQ1 Supervisors provide 4 kV ESD protection for both VDD and VSS, and feature adjustable reset timeout window. Other features include a programmable reset threshold and an operational temperature range of -40°C to +85°C. The TPS3850G12QDRCRQ1\'s fast response time and low power consumption make them a great choice for power management applications in industrial, embedded, and SCADA systems.
