The 20 mV hysteresis built into the comparator cleans up noisy input edges, preventing output chatter near the trip point. ## Quiescent current and response time Maximum quiescent current is 3.5 µA, which keeps the power budget tight for always-on sensor monitors or wake-up circuits. Input bias current is 10 pA max at 5 V, so the comparator does not load high-impedance signal sources. Propagation delay is 360 ns max — fast enough for overcurrent or undervoltage detection in moderate-speed control loops, but not intended for GHz-level switching. The output can sink 55 mA at 5 V, enough to drive a small relay coil or an LED indicator directly. ## Package and temperature grade Housed in a 4-bump DSBGA (4-XFBGA) package, the TLV4031R2YKAR occupies minimal board area — the 4-DSBGA supplier device package is a 0.8 mm × 0.8 mm footprint typical for wafer-level chip-scale packages. Surface-mount assembly requires a solder-paste stencil with small apertures; the tiny pitch demands careful PCB layout and reflow profile control.","metaTitle":"TLV4031R2YKAR Texas Instruments Comparator, 1.6-5.5V","metaDescription":"Texas Instruments TLV4031R2YKAR general-purpose comparator with fixed reference, 20 mV hysteresis, 3.5 µA quiescent, -40°C to 125°C.
