Introduction to ZM33064GTA

The ZM33064GTA is a PMIC (Power Management IC) from the family of Supervisors. It is manufactured by the US-based chip producer, Zilog. It is a monolithic integrated circuit (IC) that integrates power management, signal conditioning, and clock generation and distribution functions into a single package. The ZM33064GTA is also known as a “universal power management supervisor” because it can manage multiple voltage rails and provide a wide range of protection features. It is suitable for a variety of applications including Datacom, Telecommunications, and Industrial Automation. It is offered in a small Lead-Free/Halogen-Free package and is designed to operate in a temperature range of -40°C to 125°C.

ZM33064GTA Application Fields and Working Principle

The ZM33064GTA provides system designers and power management designers the flexibility to design various power systems with a variety of voltage rails, including 5V, 3.3V, and 1.2V. It has several operating modes, such as basic, automatic, system reset, and watchdog, which can be applied in a variety of power management applications.

• Basic Mode:

The basic mode is used for simple power management applications, and is typically the default mode of operation. In the basic mode, the ZM33064GTA continuously monitors the voltage of the power supply and initiates a reset signal to the system if the voltage drops below a pre-programmed threshold. The threshold voltage can be adjusted via the RESET pin.

• Automatic Mode:

The automatic mode provides a more complex power management scheme, and can be used for advanced applications such as fault tolerance, system reset, and power sequencing. In the automatic mode, the ZM33064GTA not only monitors the power supply voltage level but also provides over-voltage, under-voltage, and over-temperature protection. For example, if the voltage of the power supply drops below a certain threshold, the ZM33064GTA will reduce the output current of the system to prevent damage to components, and if the temperature of the power supply exceeds a certain threshold, the ZM33064GTA will shut down the system to avoid any potential hazard. The threshold voltages and temperatures can be configured via the AUTO pin.

• System Reset Mode:

The system reset mode is used for self-monitoring and resetting the system in the event of a monitored variables going out of pre-programmed thresholds. For example, if the power supply voltage exceeds a certain threshold, the ZM33064GTA will initiate a reset pulse to reset the system, so that the voltage can be brought back in its operating range. The threshold voltage can be configured via the SCLK pin.

• Watchdog Mode:

The watchdog mode uses a separate timer to monitor the system and initiate a reset pulse if the system fails to respond within a pre-programmed time period. This is useful for applications such as system hang-up or CPU lock-up. The watchdog time-out period can be configured via the WDT pin.

Conclusion

The ZM33064GTA is a versatile power management IC from the family of Supervisors. It can be used in a variety of applications, including Datacom, Telecommunications, and Industrial Automation, to provide protection and power management features.It has four different operating modes which can be adjusted according to the application requirements. The ZM33064GTA provides a cost-effective solution for robust power management of various voltage rails.
