High Accuracy, μPower, Over-Voltage Detector with Glitch Suppressor Using LTC1541 and LTC6994

May 4th 2016
An overvoltage detector which suppresses glitches is constructed from the LTC®1541 micropower op amp + comparator + voltage reference and LTC6994-1 TimerBlox® delay block/debouncer. In this circuit, the LTC1541 comparator detects power rail overvoltage conditions (including glitches). The built-in op amp inverts this ...

LT2940 1-Cell Monitor with Bottom-Side Sense

Nov 30th 2009
The LT2940 measures a high side current and a differential voltage, multiplies them and outputs a current proportional to instantaneous power. Bidirectional high side currents and bipolar voltage differences are correctly handled by the four-quadrant multiplier and push-pull output stage, which allows the LT2940 to indicate ...

LT2940 28V Power to Frequency Converter

Nov 30th 2009
In some environments isolation is necessary for safety or noise reasons. The circuit above shows a power-to-frequency converter using the LT2940. The PMON output alternately charges and discharges a film capacitor, C5. When the voltage on C5 charges to the upper threshold on hysteretic comparator LTC1440, its output flips the ...
