Working Principles

The TPS3851G50EQDRBRQ1 operates by continuously monitoring the voltage level at the VDD pin. When the voltage falls below the specified threshold, the IC asserts a reset signal on the RESET pin. The delay time for reset assertion can be adjusted according to the application requirements. Additionally, the manual reset input allows for external control over the reset signal.

During power-up, the TPS3851G50EQDRBRQ1 includes a power-on reset delay time of 200ms to ensure stable operation. The IC supports both active-low and active-high reset outputs, providing flexibility in system design.
