R3111Q171A-TR-F - Brand New RICOH IC Chips
-
Description
The R3111Q171A-TR-F is a CMOS-based voltage detector IC from the R3111x series. It is designed with high detector threshold accuracy and ultra-low supply current, making it suitable for system reset applications. The IC consists of a voltage reference unit, a comparator, resistors for detector threshold setting, an output driver, and a hysteresis circuit. With its fixed detector threshold and no need for adjustment, it offers convenience for users.
Specifications and features
The R3111Q171A-TR-F features a supply current of 0.8µA (VDD=1.5V), an operating voltage range of 0.7V to 10.0V (Topt=25°C), and a detector threshold range of 0.9V to 6.0V with an accuracy of ±2.0%. It has a temperature-drift coefficient of detector threshold of ±100ppm/°C. The IC offers three output types: Nch open drain “L”, Nch open drain “H”, and CMOS. It is available in six different package types: TO-92, SOT-89, SOT-23-3, SOT-23-5, SC-82AB, and SON1612-6.
Application Scenarios
The R3111Q171A-TR-F is commonly used in various applications, including CPU and logic circuit reset, battery checker, window comparator, wave shaping circuit, battery back-up circuit, and power failure detector.
