Renesas Electronics Corporation PMIC - Supervisors X40435S14-B

The X40435S14-B from Quarktwin Technology Ltd. is a triple voltage supervisor designed for monitoring supply voltages ranging from 1.3V to 5.5V. It features independent monitoring of three 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. This supervisor operates with a low power consumption of 25¬µA in standby mode with the watchdog active, and 6¬µA with it off. It integrates a 4Kbit EEPROM with a 2-wire I¬=C interface, allowing for efficient data storage and retrieval. The EEPROM supports a write cycle time of 5ms and includes built-in write protection to prevent inadvertent data corruption. The X40435S14-B is available in a 14-lead SOIC package and is suitable for applications in communication equipment, industrial systems, and computer systems, providing a compact solution for voltage monitoring and reset control.
