Working Principle of X5169PZ

The X5169PZ is a 3V supervisory circuit designed to monitor the power supply voltage (VCC) and reset the system when the voltage drops below a preset threshold level. The X5169PZ works on a voltage detection principle, where the voltage across a resistor is monitored by an internal comparator. If the voltage drops below the preset threshold voltage (VTH) then the output of the comparator will switch to low, and the reset signal will be triggered.

The X5169PZ features an adjustable trip point (VTH) which can be set to the desired voltage using an external resistor. It is also capable of providing an active-low reset signal to ensure the system is reset cleanly and quickly, as well as a watchdog timer for monitoring the health of the system.

Conclusion

The X5169PZ is a 3V supervisory circuit designed for monitoring the output voltages of different types of circuits. It can be used in a wide range of applications including DC-DC converters, power supplies, photovoltaic and solar cells, electronic communication systems, and general-purpose applications. The X5169PZ is a highly versatile solution that offers adjustable trip point capability, active-low reset, and watchdog timer. It is the perfect choice for monitoring and protecting 3V systems.
