Renesas Electronics Corporation PMIC - Supervisors X40626S14-2.7T1

The X40626S14-2.7T1 from Quarktwin Technology Ltd. is a dual voltage CPU supervisor that integrates multiple functions including power-on reset control, watchdog timer, dual supply voltage supervision, and a 64Kbit serial EEPROM memory. It operates within a voltage range of 2.7V to 5.5V and features low power consumption with a maximum standby current of 20µA when the watchdog is active, and 1µA when it is off. The device includes a watchdog timer with selectable timeout intervals, ensuring microcontroller protection by asserting a reset signal if the timer is not reset within the specified period. It also provides low V CC detection with four standard reset threshold voltages, which can be user-programmed for custom applications. The EEPROM memory is organized in 64-byte pages and includes built-in inadvertent write protection, enhancing data integrity during power fluctuations. The X40626S14-2.7T1 supports a 400kHz 2-wire interface, allowing for easy integration into I²C bus systems, and can accommodate up to four devices on the same bus. The product is available in a 14-lead SOIC package, making it suitable for space-constrained applications.
