Renesas Electronics Corporation PMIC - Supervisors X40420V14-A

The X40420V14-A from Quarktwin Technology Ltd. is a dual voltage supervisor designed for monitoring voltages from 5V to 1.6V. It features integrated power-on reset control, a watchdog timer, and a battery switch backup function, allowing it to maintain system operation during power failures. The device can monitor two voltage levels and has adjustable reset thresholds, with three standard settings available. It supports a low power CMOS design, with typical standby currents of 25µA with the watchdog active and 1µA in backup mode. The X40420V14-A includes 4kbits of EEPROM with a self-timed write cycle and built-in write protection. It operates over a supply voltage range of 2.7V to 5.5V and communicates via a 400kHz 2-wire interface. The device is packaged in a 14-lead TSSOP format, making it suitable for applications in communications equipment, industrial systems, and computer systems. Its features contribute to reduced system costs and increased reliability, making it a viable option for engineers looking for a compact and efficient voltage supervisor.
