LTC690CS8#PBF General Description

When it comes to power supply monitoring and battery control, the LTC690CS8#PBF stands out as a reliable and effective solution. It offers a comprehensive range of functions including microprocessor reset, battery backup, CMOS RAM write protection, power failure warning, and watchdog timing. The product's internal voltage reference and comparator circuit are designed to provide precise monitoring of the power supply line. In the event of any out-of-tolerance condition, the reset outputs are triggered, and the chip enable output write-protects external memory to safeguard important data. Moreover, the RESET output remains logic low even with VCC as low as 1V, ensuring consistent performance even in low voltage scenarios
