XC6138NARJMR-G

The XC6138NARJMR-G from Torex Semiconductor is a high-precision, ultra-low power voltage detector. It is engineered for reliable system supervision in microcontrollers and digital circuits, making it suitable for battery-powered applications like wearables and IoT devices.

Key electrical characteristics include a wide detection voltage range from 1.6V to 5.5V with an accuracy of ±1.5% at 25°C. The device boasts an exceptionally low quiescent current of only 128nA, minimizing power consumption for extended standby life. It operates within a voltage range of 1.3V to 6.0V and is available with CMOS or N-channel open-drain output configurations.

A notable feature is the separate Sense Pin (SENSE), which allows monitoring of a specific power rail even if its voltage drops to 0V, without compromising the reset signal integrity as long as the VIN pin remains within its operating range. The XC6138 series also incorporates a flexible reset delay function. While an internal delay is present, an external capacitor connected to the Cd pin can extend this delay period, ensuring system stability during power-up or brown-out conditions.

Packaged in the industry-standard SC-74A, SOT-753, this voltage detector is designed for surface mount applications. Its low temperature coefficient of ±50ppm/°C ensures reliable performance across various industrial environments.
