Introduction

The S-1009C40I-I4T1U (hereafter referred to as \'the device\') is a system supervisor combined with an adjustable reset time delay feature. It is designed to improve reliability of electronics systems by providing overvoltage and undervoltage protection, and circuit reset when needed. It belongs to PMIC - Supervisors family.

Application Field

The S-1009C40I-I4T1U is widely used in many electronics applications such as Industrial Control, Telecom Equipment, Network Systems, Automotive and Aviation industries. It is suitable for any system requiring over-voltage, under-voltage detection and an adjustable reset delay feature.

Device Features and Specifications

The S-1009C40I-I4T1U is an integrated system supervisor consisting of a successful supervisor along with several of the following features:• Over Voltage Protection (OVP)• Under Voltage Protection (UVP)• Over Temperature Protection (OTP)• Under Temperature Protection (UTP)• Input Supply range of 2.5V to 5.5V• Fixed Reset Output at VDD/2• Adjustable Reset Time Delay • Maximum Supply Current of 320mA• Operating Temperature Range of -40C to +85C• Temperature Hysteresis of 2C

Working Principle

The working principle of the S-1009C40I-I4T1U is quite simple. When the input voltage or temperature exceeds the preset limits, the device will issue a reset signal and keep it active until the event is cleared. The reset will be delayed for the configured time before releasing. The delay period is adjustable via an external resistor. The OVP and UVP are both set by external resistors. The OTP and UTP are both set by external resistors with a temperature hysteresis of 2C.

Conclusion

In conclusion, the S-1009C40I-I4T1U is a versatile system supervisor which can be used in a wide range of applications. It has a number of features including overvoltage and undervoltage protection, temperature protection, adjustable reset delay, and a maximum supply current of 320mA. It is a reliable and cost-effective solution for electronics systems requiring over-voltage, under-voltage detection, and an adjustable reset delay feature.
