The integrated reference eliminates the need for an external voltage divider or dedicated reference IC, saving board area in threshold-detection and battery-monitor circuits. The comparator's output swings rail-to-rail with CMOS, push-pull, or TTL-compatible drive, and the 8 mA typical output current can directly drive a logic input or a small load. ## 450 ns propagation delay and 72 µA quiescent — what they mean for the threshold detector The 450 ns max propagation delay sets the comparator's response speed for over-voltage, under-voltage, or zero-crossing detection. In a switching power-supply feedback loop or a fast comparator-based window detector, this delay defines the minimum pulse width the circuit can resolve. The 72 µA max quiescent current keeps the part viable for battery-powered equipment where every microamp counts — think portable medical monitors, handheld instruments, or remote sensor nodes running on a coin cell. The ±3 mV internal hysteresis cleans up slow-moving or noisy input signals without external positive feedback components. ## Supply range and temperature grade for industrial and portable gear Operating from 2.7 V to 5.5 V single supply, the MAX9050BEUK covers 3.3 V and 5 V logic rails directly. The -40°C to 85°C temperature range suits industrial control cabinets, outdoor telecom enclosures, and automotive cabin applications. Input bias current maxes at 1 pA at 5 V, so high-impedance sources like pH probes or photodiode amplifiers see negligible loading. The 80 dB CMRR and 80 dB PSRR keep the threshold accurate across common-mode shifts and supply ripple. ## Package and footprint — five-pin SOT-23 Housed in a SC-74A / SOT-753 package, the MAX9050BEUK occupies roughly the same board area as a single SOT-23 transistor. The supplier device package is SOT-23-5. Surface-mount assembly with standard reflow profiles applies; no exposed pad means the thermal path is through the pins only, so continuous output drive at 8 mA in a 85°C ambient should be checked against the junction-to-ambient thermal impedance for the specific PCB copper area. ## Lifecycle and compliance — active, but RoHS non-compliant The MAX9050BEUK carries an Active product status from Maxim Integrated, so no end-of-life notice is in effect. The RoHS compliance status is listed as non-compliant, which matters for designs targeting EU RoHS exemptions or legacy Pb-free exemptions. For RoHS-required builds, the RoHS-compliant variant in the same family should be reviewed.","metaTitle":"MAX9050BEUK Comparator with Voltage Reference, 450ns","metaDescription":"MAX9050BEUK single comparator with precision voltage reference. 450ns propagation delay, 72µA quiescent, -40 to 85°C.
