Automotive small-size comparator with integrated reference

The TLV4011-Q1 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-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 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-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 1.8-V, 3.3-V, 5-V, and adjustable supply

voltages.

The TLV4011-Q1 is available in a 5-pin

SC-70 package and are characterized for operation over a temperature range of –40°C

to 125°C.
