Renesas Electronics Corporation Supervisors X40415V8-AT1

The X40415V8-AT1 is a dual voltage monitor and integrated CPU supervisor designed for applications requiring reliable power management. It features dual voltage detection with adjustable reset thresholds, allowing for precise monitoring of supply voltages ranging from 2.7V to 5.5V. The device can monitor three voltages or detect power failures, providing a reset signal that remains valid down to 1V. This supervisor includes a selectable power-on reset timeout with options of 0.05s, 0.2s, 0.4s, and 0.8s, as well as a watchdog timer with selectable intervals of 25ms, 200ms, and 1.4s. It operates with a low power consumption of 25µA in standby mode with the watchdog enabled, and 6µA with it disabled. The X40415V8-AT1 also incorporates 4Kbits of EEPROM with a 16-byte page write mode and a typical write cycle time of 5ms. It features built-in inadvertent write protection and a 400kHz 2-wire interface for communication. The device is available in an 8-lead TSSOP package, making it suitable for space-constrained designs in communication equipment, industrial systems, and computer systems.
