TLV4021 - Small-Size, Low-Power Comparator with Precision Reference

The TLV40x1 devices are low-power, high-accuracy comparators with an internal 1.2 V or0.2 V reference and propagation delay of 450 ns. The comparators are available in an ultra-small,DSBGA package measuring 0.73 mm × 0.73 mm, making the TLV40x1 applicable for space-critical designslike portable or battery-powered electronics where low-power and fast response to changes inoperating conditions is required.

The factory-trimmed switching-thresholds and internal hysteresis combine to make theTLV40x1 appropriate for precision voltage and current monitoring in harsh, noisy environments whereslow moving input signals must be converted into clean digital outputs. Similarly, brief glitcheson the input are rejected thereby ensuring stable output operation without false triggering.

The TLV40x1 are available in multiple configurations allowing system designers to achievetheir desired output response and performance. For example, the TLV4021 features an open-drainoutput stage while the TLV4041 features a push-pull output stage. Furthermore, the TLV4021/TLV4041offer non-inverting inputs.
