TPS389050QDSERQ1

Texas Instruments’ TPS389050QDSERQ1 is a Precision Supervision, lower cost solution designed to provide best-in-class safety and performance. It is a two-stage supervisor and offers excellent accuracy and very low-power operation. It is ideal for applications requiring extra precision in monitoring and accuracy.

Features

The TPS389050QDSERQ1 offers several advantages over other solutions in its class. Its integrated precision voltage supervisor provides an adjustable overvoltage threshold from 1.595V to 5.205V with a 50mV hysteresis. It also offers fast internal power-on reset and brown-out protection by maintaining a low-current, high-accuracy voltage monitor. It features an incredibly low current consumption of 6uA and supports up to 10 adjustable reset sources.

The TPS389050QDSERQ1 is also compatible with most microcontrollers on the market and supports power-down, power-up, and open-drain reset outputs. It also includes an adjustable active-high, active-low reset time delay and low power-down threshold for improved operation.

Applications

The TPS389050QDSERQ1 supervisor is ideal for battery-powered microcontroller applications and other system monitors. It is suitable for a wide range of applications including power monitor, system monitor, data signal line monitor, over-voltage protection, reset controller, PC power supply, and SMART battery systems. The superb precision and current-consumption is also well suited for battery-powered applications that require frequent operations.

Working Principle

The TPS389050QDSERQ1 is designed to monitor the power supply lines in a system and trigger a reset whenever the power supply drops below a certain level. When the power reaches the predetermined threshold, the reset signal is triggered and the microcontroller is reset. This reset signal may be used to reset the entire system or just a certain portion of it. The reset signal generated by TPS389050QDSERQ1 is also capable of triggering an interrupt or an action to any connected device.

The TPS389050QDSERQ1 is an ideal supervisor solution for cost-sensitive battery-powered applications. Its superior accuracy, low current-consumption, and adjustable thresholds make it perfect for a wide range of applications that require precision monitoring and accuracy. The TPS389050QDSERQ1 is an excellent choice for applications that need a reliable and efficient power control system.
