Introduction

PMIC stands for Power Management Integrated Circuit and Supervisors are a separate category within the PMIC industry. Supervisors are specialized ICs designed to monitor the status of the system and its operating voltage, respond to changes in these conditions, and take the necessary corrective action. The S-1009N23I-I4T1U is an example of a supervisor IC. It is an ultra-low power voltage supervisor IC with a wide spacing between its onboard voltages and an adjustable reset time.

Application Field

The S-1009N23I-I4T1U has a wide range of applications in the industrial, automotive, medical, and consumer markets. Its low power consumption and wide spacing between its onboard voltages make it suitable for use in both low-power and high-accuracy applications.In automotive applications, the S-1009N23I-I4T1U can be used to monitor battery voltage and to detect and protect against voltage fluctuations and spikes. It can also be used to detect engine-stop conditions and to take the necessary action.In industrial applications, it can be used to monitor temperature and pressure, providing an alarm when a certain value is exceeded. It can also be used to detect power-out conditions and to enable an immediate shutdown.In medical applications, it can be used to monitor the battery level of medical equipment, provide an alarm if the level drops too low, and protect against voltage spikes. It can also be used to detect and respond to faults in the power supply system.Finally, in consumer applications, it can be used to detect low battery levels in portable devices and to protect against voltage spikes.

Technical Characteristics

The S-1009N23I-I4T1U is designed to operate with input voltages in the range of 1.2V to 15V. It has a 0.9 µA operating current and a maximum voltage detection accuracy of ± 2%. It is offered in a temperature range of -30°C to 85°C, with a maximum reset time of 500 ms.

Features and Benefits

Some of the features and benefits of the S-1009N23I-I4T1U include:

• Low power consumption.
• High voltage detection accuracy.
• Wide input voltage range.
• Wide temperature range.
• Adjustable reset time.

Working Principle

The working principle of the S-1009N23I-I4T1U is based on the use of two comparators. The first comparator monitors the input voltage and compares it with a voltage reference. If the input voltage is lower than the reference voltage, the first comparator triggers the second comparator, which then generates a reset signal. This reset signal is then used to reset the system or take the appropriate action.

Conclusion

The S-1009N23I-I4T1U is an ultra-low power voltage supervisor IC with a wide spacing between its onboard voltages and an adjustable reset time. It has a wide range of applications in the industrial, automotive, medical, and consumer markets. Its wide input voltage range and adjustable reset time make it suitable for use in both low-power and high-accuracy applications. Its working principle is based on the use of two comparators, which monitor the input voltage and compare it with a reference voltage. If the input voltage is lower than the reference voltage, the second comparator triggers a reset signal, which is then used to reset the system or take the appropriate action.
