BU7250G-TR

Comparators Overview

The BU7250G-TR is a single-channel analog comparator manufactured by ROHM Semiconductor, housed in a 5-SSOP surface-mount package. It operates on a single supply voltage ranging from 1.8 V to 5.5 V with a typical quiescent current of 35 µA. The device features an open-drain output capable of sourcing 6 mA and supports full input common-mode voltage range from Vss to Vdd. Key electrical specifications include a maximum input offset voltage of 11 mV and an input bias current of 1 pA. It functions within a temperature range of -40°C to +85°C.

Comparators Feature Summary

• Supports full-swing input voltage range extending from the negative supply rail to the positive supply rail.
• Provides low power consumption suitable for battery-operated applications with minimal quiescent current draw.
• Features an open-drain output configuration allowing flexible interfacing with various logic families.

Comparators Applications

• Low-voltage signal processing circuits
• Battery-powered portable devices
• General-purpose threshold detection

Comparators Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm that the SSOP-5 package dimensions match the target PCB footprint. Ensure the operating environment remains within the specified -40°C to +85°C range to maintain guaranteed performance parameters. Check RoHS compliance status if required by local regulations.

Comparators Selection Notes

Select this component when a single comparator with rail-to-rail input capability is required in a compact surface-mount package. It is appropriate for designs prioritizing low static current over high-speed switching. Consider alternative packages if higher pin counts or different thermal characteristics are needed. Verify that the open-drain output requirement aligns with the system's pull-up resistor strategy.

Comparators Part Context

This part belongs to the BU7250 series of CMOS comparators designed for low-voltage operation. It shares functional similarities with other members of the family but is distinguished by its single-channel configuration and specific output stage type. The series targets cost-sensitive applications requiring reliable comparison functions in small form factors.
