Power Management Integrated Circuit (PMIC) supervisor products are an important class of device that are used in power applications. They serve several roles in power supply circuitry, in particular providing protection against extreme current and voltage conditions, and for generating response signals for restore operation. The S-80128ANPF-JCNTFG Power Management IC supervisor, from ON Semiconductor, is a one-time configuration, low current supervisor that is built on a power-efficient, low-voltage CMOS process. This supervisor offers excellent protection against voltage trips, current conditions, and temperature. The article looks at the application field of S-80128ANPF-JCNTFG, and its working principle.

Application Field of S-80128ANPF-JCNTFG

The S-80128ANPF-JCNTFG is ideal for applications in mobile and embedded systems, such as mobile phones, PDAs, and digital picture frames, which require low current and cost-effective protection against power supply voltage and current trips. It is also suitable for use in servers, where it can provide integral protection from surges, ESD, and over temperature conditions. The S-80128ANPF-JCNTFG is a low current, low voltage supervisor and can operate from 1.8 to 5.5V. This makes it well suited for applications that require lower supply voltages. It is capable of monitoring up to five voltage and current lines simultaneously. It also provides an active high and active low voltage trip flags for each monitored line, which can be used to control other parts of the system.

The S-80128ANPF-JCNTFG features an integrated temperature sensor that monitors the junction temperature of the system. If the temperature exceeds a specified level, the device can automatically shut down the system and safely restart it when the temperature has returned to normal. This feature provides additional protection to the system against potential overload and over-temperature conditions.

The S-80128ANPF-JCNTFG is a one-time configuration device, which means that the user only needs to configure the device once, during the design phase. This is beneficial for system integrators, as it simplifies the design process and reduces time to market. The one-time configuration also reduces the cost for the user, as the system integrator does not need to purchase an additional programming chip.

Working Principle of S-80128ANPF-JCNTFG

The operation of the S-80128ANPF-JCNTFG is based on the use of voltage and current thresholds, to monitor the various voltages and currents present on the system. When the monitored voltage and/or current exceeds the pre-set threshold, the device will generate a response signal, which can be used to control other parts of the system. The response signal can be active high, active low, or both, depending on the configuration of the device. The response signal can be used to control other parts of the system, such as a reset circuit. The device can also be configured to monitor the junction temperature of the system, providing an additional layer of protection in the event of an over-temperature condition.

The S-80128ANPF-JCNTFG has a few other features that can be enabled or disabled, depending on the system\'s requirements. These include a power-on reset input, which enables the system to be reset when power is cycled, as well as a watchdog timer input, which can be used to reset the system if it is not responding properly. The device also supports reverse battery protection, which prevents the system from being operated in reverse polarity.

One of the key advantages of the S-80128ANPF-JCNTFG is its low current consumption. The device typically consumes only 40µA of current when operating at its maximum voltage, which makes it an attractive solution for applications where power consumption must be minimized. This is particularly beneficial for mobile and embedded systems, which tend to run on battery power and require a low current consumption to maximize battery life. Finally, the S-80128ANPF-JCNTFG also provides an adjustable Trip Delay Threshold, which can be used to adjust the delay between the trip condition and the response signal.

Conclusion

The S-80128ANPF-JCNTFG Power Management IC supervisor, from ON Semiconductor, is a one-time configuration, low current supervisor that is well suited for applications that require low current and cost-effectively protect against power supply voltage and current trips. It is ideal for mobile and embedded systems, servers, and other applications that require low current and cost-effective protection. It can also be configured to monitor the junction temperature of the system. The one-time configuration of the device reduces the cost and time to market, while the low power consumption makes it well suited for battery powered applications. Finally, the adjustable Trip Delay Threshold ensures that the system responds correctly to elevated current and/or voltage conditions.
