Renesas Electronics Corporation PMIC - Supervisors X40414S8I-CT1

The X40414S8I-CT1 is a dual voltage monitor and integrated CPU supervisor designed for applications requiring reliable power management. It features dual voltage detection with adjustable reset thresholds, allowing for precise monitoring of supply voltages ranging from 1.0V to 3.6V. The device includes a fault detection register and can monitor three voltages or detect power failures, enhancing system reliability. This supervisor incorporates a selectable power-on reset timeout and a watchdog timer with multiple interval options, providing flexibility in system design. It operates with a low power consumption of 25µA in standby mode with the watchdog active, and 6µA with it off. The device also includes 4Kbits of EEPROM with a built-in write protection mechanism, ensuring data integrity during power fluctuations. The X40414S8I-CT1 supports a 400kHz 2-wire interface and operates within a supply voltage range of 2.7V to 5.5V. It is available in an 8-lead SOIC package, making it suitable for various communication equipment, industrial systems, and computer applications. This product is not recommended for new designs, and engineers should consider alternative solutions for future projects.
