PMIC - Supervisors: S-80848CLMC-B69T2G Application Field and Working Principle

Power management integrated circuits (PMICs) are a class of devices which “manage, regulate, and monitor all of the different kinds of power and electricity in a given system”. PMICs serve a critical purpose in controlling and regulating the operation of electrical components. One type of PMIC is the supervisor, which is responsible for monitoring the power state of a given system. In this article, we will discuss the S-80848CLMC-B69T2G application field and working principle, two of the main characteristics of a supervisor-type PMIC.

Application Field

The S-80848CLMC-B69T2G is a product of Supertex, Inc., a US-based electronic device manufacturer. The S-80848CLMC-B69T2G is a supervisor PMIC specifically designed for use within portable, energy-sensitive products such as medical and industrial devices. The PMIC has a wide input voltage range of 2.5V-20V and a quiescent current of only 100nA, allowing it to operate efficiently in mobile and battery-powered systems. In addition, its slim surface-mount design allows for use in devices with limited space restrictions. The S-80848CLMC-B69T2G is a 4-channel supervisor and offers the ability to monitor the voltage of four different supply rails. It provides three adjustable reset thresholds for each voltage rail and can also be configured for use in systems with an optional third reset threshold. The monitoring outputs of the S-80848CLMC-B69T2G can be configured for either active-high or active-low logic signaling. In addition, the device’s internal watchdog timer has a maximum timeout period of 2 minutes.

Working Principle

Supervisor PMICs such as the S-80848CLMC-B69T2G are used to monitor the power status of a given system. The internal circuitry of the device continuously monitors the voltages of up to four different power rails. If the detected voltage falls below an adjustable threshold, the supervisor will generate an active-high or active-low reset signal, depending on the internal configuration. The device also further provides an adjustable internal watchdog timer which is used to detect system faults and prevent catastrophic failure. The S-80848CLMC-B69T2G also has a built-in temperature monitor and has the ability to issue a warning when the monitored temperature exceeds a certain level. The supervisor also provides power-on reset capability and can be configured to generate a reset signal when powered on. In addition, the device allows for optional manual reset inputs as well as manual reset outputs, allowing for further customization and control over the system’s power state.

Conclusion

In this article, we discussed the S-80848CLMC-B69T2G application field and working principle. The S-80848CLMC-B69T2G is a supervisor PMIC designed for use in portable, energy-sensitive products such as medical and industrial devices. The device has a wide input voltage range of 2.5V-20V and can monitor the voltages of four different supply rails. The device also provides three adjustable reset voltages, power-on reset capability, and an adjustable watchdog timer. Its slim surface-mount design makes it suitable for use in devices with limited space restrictions.
