Comparator for over-voltages
To maintain an alarm condition when an overvoltage transient disappears, an SCR should be added to the comparator circuits. For SCR operation, the voltages to the comparator inputs are inverted. The triple-voltage monitoring circuit detects transient power-supply over-voltages. If excessive...
Comparator Based Crystal Oscillator
A simple crystal oscillator can be constructed using a comparator from the LT1720/LT1721 series; however, this design may encounter several inherent limitations and issues. While the LT1720/LT1721 provides the correct logic output when one input falls outside the common mode...
SC1437 Precision Voltage Detector With Programmable Trigger Voltage & Timer Delay - Semtech Corporation
The SC9256 is a phase-locked loop (PLL) integrated circuit designed for digital tuning systems (DTS), featuring built-in 2 modulus prescalers. All functions are controlled through three serial bus lines. These integrated circuits are utilized to configure high-performance digital tuning systems....
IC Magnitude Comparators
This Magnitude Comparator can be used to perform comparisons of two 8-bit binary or BCD words. The output provides both a P equals Q function and a P greater than Q function. A Magnitude Comparator is typically classified as standard...
Motor Control Circuit of LM339
The motor control circuit depicted in the image utilizes the LM339 comparator among other components. When the input control signal is high (PWL), comparators A and A3 activate the power amplifier circuit, which consists of A4, VT5, and VT6, thereby...
Tunable single comparator oscillator
Varying the amount of hysteresis in this comparator circuit allows for smooth adjustment of output frequencies within the range of 740 Hz to 2 kHz. The hysteresis level, in combination with the time constant formed by resistor R6 and capacitor...
HT7070A Voltage Detector
The HT70XX series comprises a collection of three-terminal low-power voltage detectors constructed using CMOS technology. Each voltage detector within the series is designed to detect a specific fixed voltage within the range of 2.2V to 7V. These detectors feature a...
Digital Main Voltage Indicator
Continuous monitoring of mains voltage is essential in various applications, including manual voltage stabilizers and motor pumps. Although an analog voltmeter is cost-effective, it has several drawbacks due to its moving parts and sensitivity to vibrations. The solid-state voltmeter circuit...
Voltage detector relay
While the battery is charging, its voltage is measured at V. If the measured voltage is lower than the minimum threshold, the relay will be activated, connecting the charger circuit. When the battery voltage exceeds the maximum set point, the...
