LTC2911CTS8-5#TRMPBF

LTC2911 is a low power, high accuracy triple supply monitor with a power-fail comparator. Reset timeout may be selected with an external capacitor or set to an internally generated 200ms. A third adjustable input has a nominal 0.5V threshold allowing a resistive divider to configure its threshold. All three comparators feature a tight 1.5% threshold accuracy over the entire operating temperature range while a glitch filter ensures reliable reset operation. A spare comparator can be configured to provide early warning of a low voltage condition. It causes the PFO output to pull low when the voltage of the PFI input falls below 0.5V, allowing the power-fail threshold to be configured with a resistive divider. A latch feature on the TMR pin allows the RST output to be latched to prevent system resets, simplifying margin testing. It is used in application such as network servers, desktop and notebook computers, automotive and industrial electronics etc.
