The X40421S14-A from Quarktwin Technology Ltd. is a dual voltage supervisor designed for monitoring supply voltages ranging from 5V to 1.6V. It features integrated power-on reset control, a watchdog timer, and a secondary voltage monitoring capability. The device can assert reset signals based on three standard threshold settings (4.6V/2.9V, 4.6V/2.6V, 2.9V/1.6V) and allows for programmable low voltage reset thresholds down to 0.9V. This supervisor includes a battery switch backup function, enabling it to provide power from either the main supply or a backup battery, ensuring system reliability during power failures. It can output current from 5mA to 50mA from the main supply and 250µA from the battery. The device operates with a typical standby current of 25µA with the watchdog enabled and 1µA in backup mode. The X40421S14-A also incorporates a 4kbit EEPROM with write protection features and a 400kHz 2-wire interface for communication. It is available in 14-lead SOIC and TSSOP packages, making it suitable for various applications, including communications equipment, industrial systems, and computer systems.
