Texas Instruments TLV4011/TLV4011-Q1 Precision Comparators

Texas Instruments TLV4011/TLV4011-Q1 Precision Comparators are low-power, high-accuracy comparators with a precision, integrated reference. Two external resistors can be connected to the input to create an adjustable voltage threshold down to 1.226V. The factory-trimmed switching threshold and precision hysteresis combine to make the TLV4011/TLV4011-Q1 appropriate for voltage and current monitoring in harsh, noisy environments where slow-moving input signals must be converted into clean digital outputs. Similarly, brief input glitches are rejected, ensuring stable output operation without false triggering.

RESET is asserted (LOW) during power-on when the supply voltage VDD becomes higher than 0.8V. Afterward, the TLV4011/TLV4011-Q1 monitors the input and keeps RESET active (LOW) while the input remains below the threshold voltage VIT. As soon as the input rises above the threshold voltage VIT, RESET is de-asserted (HIGH). The product spectrum is designed for 1.8V, 3.3V, 5V, and adjustable supply voltages. The TLV4011/TLV4011-Q1 is available in a 5-pin SC-70 package and is characterized for operation over a temperature range of –40°C to 85°C. The Texas Instruments TLV4011-Q1 devices are AEC-Q100 qualified for automotive applications.
