Additional Details

The 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.

The V1 pin monitors a 3.3V supply. The V2 pin monitors a 5V, 2.5V, 1.8V, 1.2V or adjustable supply. 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.
