Introduction

The TPS3103K33DBVT is a supervisor device designed to provide backup power and keep a main power supply stable. It consists of two main parts – a supervisor and an oscillator, connected along with other components to form a single integrated circuit. The supervisor monitors the voltage of a Vdd rail, and if it drops below a predetermined threshold, the supervisor will suitably output a signal to the oscillator.

Application Field and Working Principle

The TPS3103K33DBVT is particularly useful in applications such as computer peripherals and other embedded systems, where it grants extra protection from sudden power failure. The supervisor part of the device will turn on if the Vdd rail power falls below its threshold voltage. The oscillator will then output a steady square wave signal, providing enough power to maintain the system until the main power supply is restored. It has fast Startup, low operating current consumption, 1μA type and low power consumption.

The TPS3103K33DBVT has an on-chip oscillator that can be programmed with frequency options ranging from 1 kHz to 1 MHz. It also has a pin that enables adjustment of the voltage threshold. The device also includes a push-pull output with open drain and internal pull-up, capable of delivering up to 10mA at 5V for the backup current source circuit. This integrated circuit is robust and cost-efficient, making it an ideal solution for embedded systems.

Conclusion

To summarize, the TPS3103K33DBVT is a powerful supervisor device designed to provide a backup current source circuit that keeps a main power supply stable. It is widely used in embedded systems and computer peripherals, where it offers protection from sudden power failure. The on-chip oscillator offers programming with frequency options and the device also has an adjustable voltage threshold. With low operating current consumption, fast startup, and low power consumption, it is a robust and cost-effective solution.
