Renesas Electronics Corporation PMIC - Supervisors X40434S14-A

The X40434S14-A from Quarktwin Technology Ltd. is a triple voltage supervisor designed to monitor voltages ranging from 1.3V to 5.5V. It features independent monitoring of three separate voltage levels, with adjustable reset thresholds and a power-on reset function that ensures system stability during startup. The device includes a watchdog timer with selectable intervals, a manual reset input, and a fault detection register for enhanced reliability. This supervisor operates with a typical standby current of 25¬µA when the watchdog is active and 6¬µA when it is off. It incorporates 4Kbits of EEPROM with a 5ms write cycle time and built-in write protection to prevent inadvertent data corruption. The X40434S14-A supports a 400kHz 2-wire interface, making it compatible with I¬=C bus systems. It is available in 14-lead SOIC and TSSOP packages, suitable for applications in communication equipment, industrial systems, and computer systems.
