TLV4011中文资料具有集成基准电压的小型比较器数据手册TI规格书

描述 Description

The TLV4011 is a low-power, high-accuracy comparator with a precision, integrated reference. Two external resistors can be connected to the input to create an adjustable voltage threshold down to 1.226 V.

The factory-trimmed switching threshold and precision hysteresis combine to make the TLV4011 appropriate for voltage and current monitoring in harsh, noisy environments where slow moving input signals must be converted into clean digital outputs. Similarly, brief glitches on the input are rejected thereby ensuring stable output operation without false triggering.

During power on, RESET is asserted (LOW) when the supply voltage VDD becomes higher than 0.8 V. Thereafter, the TLV4011 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 1.8-V, 3.3-V, 5-V, and adjustable supply voltages.

The TLV4011 is available in a 5-pin SC-70 package and are characterized for operation over a temperature range of –40°C to 85°C.
