The SSP61CN3902MR with Microprocessor & Microcontroller Supervisors SOT23-3 RoHS is an integrated circuit (IC) manufactured by Siproin. This IC is a Supervisor with a built-in microprocessor and microcontroller and is designed to protect systems against power supply and reset problems. It has a 3-pin SOT23 package and is compliant with RoHS standards. It monitors the power and reset of the system, and can be configured to generate an output reset pulse when either of these events is detected. Additionally, the IC has a power-on reset (POR) feature that is used to guarantee proper system initialization when power is applied. The IC power voltage range is from 2.2V to 5.5V. This makes it suitable for use in applications operating between 2.2V and 5.5V, such as many battery-powered systems.
