PMIC - Supervisors

The X5169P is a high-end PMIC supervisor that is designed to provide basic power management, safety and control functions. It is designed to power microprocessor cores and peripheral devices while providing reliable system supervision. The X5169P integrates a wide range of features required for high-end power system design, including voltage/current monitoring, device reset, system reset and wake-up functions. Furthermore, this PMIC supervisor can protect the system from reset due to ESD, over-voltage, over-current and over-temperature conditions.

Applications

The X5169P is ideal for use in embedded systems in the Industrial, Automotive, Medical and Smart Home markets. It is specifically designed for systems with advanced power management, safety and control requirements. As the complexity of embedded systems continues to increase, more applications are expected to be developed with the X5169P as the main power and control component.

Working Principle

The X5169P is an advanced PMIC supervisor that allows the system power, system reset, and wake-up of devices in closed-loop, or open-loop control arrangements. The X5169P allows the system design to power, reset, and wake up devices with an industry-standard Power-on-Reset (POR) signal, and a Reset-on-Keypad-Activity (RKA) signal. The POR signal is generated when a system is powered on and is used to reset the system. The RKA signal is generated when a user presses a key on the keypad and is used to reset the system. To prevent accidental reset, the X5169P has a system reset monitoring circuit that monitors activity on the RKA line and prevents an accidental reset. The X5169P can also be used to monitor voltage levels and power-on the microprocessor core and the peripherals when the conditions are met. The X5169P can monitor the supply voltage range and will generate an over-voltage reset signal if the voltage level is too high or a low voltage reset signal if the voltage is too low. The X5169P also has a power-on reset signal that will automatically reset the system after a period of time. This time can be set by programming the X5169P.

Safety and Control

The X5169P is a critical component for system safety and control. It protects the system from reset due to ESD, over-voltage, over-current and over-temperature conditions. It also monitors voltage levels and can reset the system if the voltage level is too high or too low. Additionally, the X5169P can monitor supply voltage during power-up and power-down events and reset the system if necessary. Furthermore, the X5169P can detect when the system is in an idle state and power down the system accordingly.

In addition to safety and control, the X5169P supports various system management functions such as system power sequencing, supply voltage sequencing, and power-on reset pulse generation. The X5169P also provides Wake-on-USB and Wake-on-LAN wake-up signals and has programmable wake-up and reset times. Furthermore, the X5169P has the ability to detect the system power supply and detect over-current conditions.

Conclusion

The X5169P is an advanced PMIC supervisor that provides advanced power management, safety and control features. It is ideal for use in high-end embedded systems in the industrial, automotive, medical and smart home markets. The X5169P can provide reset and wake-up signals, monitor supply voltages, reset the system if the voltage is too high or too low, and power down the system if it is in an idle state. The X5169P also provides system power sequencing, supply voltage sequencing, power-on reset pulse generation, wake-on-USB, Wake-on-LAN, and various programmable wake-up and reset times. The X5169P is a great solution for any system with advanced power management, safety and control requirements.
