PMIC - Supervisors

The ZSM380GTC is an advanced, high performance reset supervisor designed to monitor and report system activity during start up and operation. Offered in an 8-pin thin small outline package (TSOP), it is a cost effective solution for applications such as personal computers, servers, storage systems, industrial electronics and instrumentation. The ZSM380GTC provides an adjustable reset timeout period, adjustable reset threshold voltage range, precision voltage monitoring and active-low reset output.

Application Field

The ZSM380GTC is used in system monitoring and reset functions in a variety of applications. Its adjustable reset timeout period and adjustable reset threshold voltage range make it well-suited for computers, servers, storage systems, industrial electronics, and instrumentation. Additionally, the device is particularly effective in applications where it can monitor multiple supplies, such as applications that use multiple-supply power systems.

Working Principle

The ZSM380GTC is primarily used for the purpose of resetting a system. When the input voltage to the device drops below the set threshold voltage, the output of the device will be driven low, triggering a reset. The device uses an adjustable reset timeout period to specify how long the output will remain low before it automatically resets the system back to its baseline state. Additionally, the ZSM380GTC employs precision voltage monitoring capability that monitors multiple supplies and reports the activity of each voltage to the system.

The ZSM380GTC can also be used in systems that require adjustable supply voltage monitoring. The device can be used to sense when the input voltage drops below a predefined voltage level, then the output can be driven low, notifying the system that the voltage has dropped. Additionally, the device utilizes a selectable reset timeout period to specify how long the output should remain low before resetting the system back to its baseline state.

In addition to system reset and supply voltage monitoring, the ZSM380GTC utilizes advanced diagnostic and reporting capabilities. Utilizing the device’s on-chip diagnostic pin (DIAG#), a system can monitor the health of internal components and report any problems encountered. Additionally, users can utilize the adjustable reset threshold voltage to ensure that their system behaves as expected during normal operation and during reset events.

Conclusion

The ZSM380GTC is a versatile, high performance reset supervisor designed for system monitoring and reset capabilities. It features an adjustable reset timeout period, adjustable reset threshold voltage range, and precision voltage monitoring capabilities. Additionally, it utilizes advanced diagnostic and reporting features that allow the device to monitor the health of the system. The device is an ideal solution for a variety of applications such as personal computers, servers, storage systems, industrial electronics, and instrumentation.
