LTC2900-1CMS#PBF

The LTC2900-1CMS#PBF is the epitome of precision and efficiency in voltage supervision for microprocessor systems. With an ultra-accurate voltage detection circuit boasting 0.5% threshold accuracy throughout the temperature spectrum, this IC ensures consistent and reliable monitoring of power supplies. Operating within a broad supply voltage range of 1.5V to 5.5V, it offers versatility and compatibility with various system configurations. Despite its robust performance, the LTC2900-1CMS#PBF maintains an impressively low supply current of only 18µA, making it an energy-efficient choice for power-sensitive applications. Equipped with a debounced manual reset input and watchdog timer, this IC goes above and beyond basic supervision duties, enabling advanced system monitoring functionalities. The open-drain active-low RESET output provides a convenient mechanism for system resets in response to voltage irregularities. Packaged in a compact 10-lead MSOP form factor, the LTC2900-1CMS#PBF is a space-saving solution tailored for applications where size constraints are a concern, delivering unmatched performance in a compact package
