PMIC - Supervisors: S-80133BLPF-JESTFG application field and working principle

PMIC(Power Managment Integrated Circuit) Supervisor is a class of semiconductor products that combines power management functions, such as voltage regulation and over-current protection, into a single integrated circuit (IC). The S-80133BLPF-JESTFG is a high-performance supervisor circuit featuring voltage reset, delay reset and manual reset control. It is widely used in automotive, telecom, industrial and consumer electronics applications to help protect and improve power system reliability.

Application Field

The S-80133BLPF-JESTFG is designed for a wide range of power management and monitoring applications. It is mainly used in data transmission, digital products, such as VCD, TV and other related electronic products. The product can also be used in a variety of computer motherboards, peripheral devices such as printer cards and so on. Also, it can be used for audio, automotive and computer power management.

Working Principle

The S-80133BLPF-JESTFG features automatic reset, manual reset and delay reset which is triggered by low battery, over-voltage and over-current protection. At start-up, the reset circuit is activated and the controller is reset to a defined initial state. The circuit monitors the power supply voltage and waits until the voltage reaches the reset threshold. When the threshold is reached, the circuit generates a reset pulse that clears the logic states of the controller. The circuit is also able to detect power supply faults through its open-source and current-sense inputs. In the case of an open-source input, the circuit will automatically trigger a reset without waiting for the voltage to reach the threshold. In the case of an over voltage or current, the circuit will monitor the voltage or current limits and generate a reset if the limits are exceeded. The circuit also provides a “manual reset” input pin that can be used to manually trigger a reset when needed. This can be used to clear any inconsistency in the current state of a system.

In addition, the S-80133BLPF-JESTFG also features a delay reset function that allows the controller to enter a safe initial state before the controller starts operating. The delay reset feature can be used to prevent any unexpected actions from occurring during the start-up of a system.

Conclusion

The S-80133BLPF-JESTFG is a high-performance supervisor circuit with voltage reset, manual reset, delay reset and open-source protection. It is widely used in data transmission, digital products, audio, automotive and computer power management applications. The circuit is designed to detect power supply faults, and provide a reset signal when the faulty condition is detected or exceeded. The delay reset function is also useful in helping the system start up in a safe and consistent manner.Overall, the S-80133BLPF-JESTFG is a versatile and reliable supervisor circuit that greatly simplifies power management and fault protection in various applications.
