The HX61CC2502MR is a microprocessor and microcontroller supervisors manufactured by Hengjiaxing. It has an SOT-23-3L RoHS package that is designed to monitor three supervised power sources. It features fail-only output, which will switch to active state when an undervoltage fault is detected on any one of the three input supply voltage monitors. This supervisor is well-suited for use in portable electronic devices, such as cell phones, PDAs, and digital cameras. Additionally, it has an extensive operating temperature range (-40 to 85°C) and low power consumption.
