Working Principle

The TC54VN1702EZB operates under the principles of linear voltage regulation. It uses a voltage reference to compare the input voltage to a preset threshold and triggers a reset signal if the voltage level drops below the threshold. The TC54VN1702EZB also features an adjustable reset threshold, allowing for the reset point to be set within a wide range between 1.2 and 5.5V. This adjustment is done through a single resistor connected to an external voltage source.

The TC54VN1702EZB has a low power consumption of 17μA, and a typical current consumption of 130μA , allowing for longer battery life in mobile or portable systems. It is also designed to be immune from transients associated with switching power sources, as well as brown-out conditions. Finally, the PMIC-Supervisor has a hysteresis of ±80mV, ensuring accurate reset detection.

Conclusion

The TC54VN1702EZB is a versatile, cost-effective Supervisory PMIC. With its adjustable reset threshold, low power consumption and immune to transients, it is suitable for a wide variety of applications, ranging from automotive and industrial to portable electronics. The TC54VN1702EZB is available in an SOP-8 package, making it an ideal solution for small, low-power systems.
