Key Features
- Low input offset voltage of 2.5 mV maximum for accurate threshold detection
- Ultra-low input bias current of 25 nA maximizing compatibility with high-impedance resistive divider networks
- Wide single-supply range from 2 V to 36 V with open-collector output for flexible logic-level interfacing
Applications
The TL331BIDBVR is ideal for threshold detection in battery monitors, over-voltage or under-voltage alarm circuits, and zero-crossing detectors in power-supply and motor-drive systems. Its open-collector output allows wired-OR connection of multiple comparators on a shared alarm bus, reducing component count in multi-fault detection designs. The SOT-23-5 package enables dense placement on space-constrained boards for portable consumer and industrial equipment.

Frequently Asked Questions
How accurate is the TL331BIDBVR threshold detection compared to a standard LM393 comparator?
The TL331BIDBVR specifies a maximum input offset voltage of 2.5 mV, which improves on the LM393 typical 5 mV offset. At a 3.3 V supply with a resistive divider setting a 1.65 V threshold, the 2.5 mV maximum error translates to less than 0.15% trip-point uncertainty, making TL331BIDBVR more suitable for precision voltage detection in battery protection circuits.
Can the TL331BIDBVR drive a 5 V logic input directly from a 3.3 V comparator supply?
Yes. The open-collector output of the TL331BIDBVR allows the pull-up resistor to be connected to a voltage rail different from the comparator supply. Powering the comparator from 3.3 V while connecting a 10 kΩ pull-up to a 5 V rail lets the output signal swing to 5 V logic high, enabling direct interfacing to 5 V microcontrollers without a level-shifter IC.
What supply voltage range does the TL331BIDBVR support for single-supply industrial applications?
The TL331BIDBVR operates from a single supply of 2 V to 36 V, covering 3.3 V, 5 V, 12 V, and 24 V industrial rails with a single part. It can also be used in a split supply of ±1 V to ±18 V, making it versatile for both low-voltage portable equipment and 24 V industrial control systems.
How small is the TL331BIDBVR footprint and when does the SOT-23-5 package offer an advantage over SOIC-8 dual comparators?
The SOT-23-5 package measures approximately 2.9 mm × 1.6 mm, versus roughly 5 mm × 4 mm for an SOIC-8 dual comparator. When only 1 comparator channel is needed, TL331BIDBVR consumes about 60% less PCB area than a dual package and avoids leaving an unused channel floating, which simplifies layout review and reduces power draw in battery-sensitive designs.
