TPS3850H25QDRCRQ1

TPS3850H25QDRCRQ1 is a Supervisor device which belongs to PMIC (Power Management Integrated Circuit) products. This device provides an accurate way to monitor and protect a power supply system. It monitors an external voltage rail and can issue reset, interrupt and power-good signals depending on the monitored voltage.

The TPS3850H25QDRCRQ1 is typically used for systems powered by the main 3.3V or 5V supply and provides an additional level of safety, by enabling the system to respond and take appropriate action, in case of a power failure or over-voltage condition. It features a precision voltage, temperature and current monitor that can be used for triggering an interrupt or reset signal for system supervisory functions.

In terms of its application field, the TPS3850H25QDRCRQ1 can be used in many different systems involving digital and analog power devices, such as micro-controllers, FPGAs, LCDs, Motor Control circuits and Mixed-Signal systems. Additionally, it can also be used in consumer appliances such as smartphones and tablets. It can also be used in a wide range of industrial and medical applications.

The TPS3850H25QDRCRQ1 contains two high-precision voltage detectors that monitor VDD and VDDQ pins. It has an adjustable supply monitor, which monitors the voltage at VDDQ pin. Additionally, it is equipped with an analog temperature monitor, which is used to detect temperature rise in the system which detects temperature rise in the system. Furthermore, it has an adjustable current monitor which can detect over-current conditions and shut down the system in case of an over-current condition.

The main working principle of the TPS3850H25QDRCRQ1 is the continuous monitoring of two external voltage supplies, VDD and VDDQ A reset signal is issued when either voltage supply falls below the pre-set threshold. The TPS3850H25QDRCRQ1 also monitors the temperature of the system and can be programmed to issue an interrupt or reset signal in case of a temperature rise above a certain level. In addition, the device can be programmed to monitor currents in the supply line, in order to detect over-current conditions.

In conclusion, the TPS3850H25QDRCRQ1 is a microprocessor supervisor device which provides additional safety for the power supplies in a system. It can monitor two external voltage supplies, temperatures and currents, and can be programmed to issue an interrupt, reset or power-good signal, depending on the monitored values. It is typically used in digital and analog power devices, consumer applications such as smartphones, tablets and industrial and medical equipment.
