Texas Instruments TLV9020DBVR

Overview

TLV9020DBVR from Texas Instruments is a single-channel precision comparator with open-drain output, rail-to-rail fault-tolerant inputs (–0.2 V to 5.7 V), 300 µV max input offset voltage, and 100 ns propagation delay at 5 V supply. It operates from 1.65 V to 5.5 V and supports industrial temperature range (–40°C to +125°C), enabling use in low-voltage logic translation and precision voltage monitoring in noisy motor drive systems.

For engineers reviewing the TLV9020DBVR datasheet, TLV9020DBVR pinout, TLV9020DBVR application, or TLV9020DBVR equivalent, key selection criteria include its open-drain output compatibility with mixed-voltage interfaces, ultra-low 16 µA per-channel quiescent current, 5 pA input bias current for high-impedance sensing, and fault-tolerant input capability up to 6 V beyond V– without phase inversion or damage.

Technical Context

The TLV9020DBVR implements a precision comparator architecture with ESD-hardened, fault-tolerant input stage capable of accepting common-mode voltages up to 6 V independent of supply rails. Its open-drain output supports flexible pull-up configurations-below, at, or above V+-enabling level-shifting across voltage domains.

Internally, it features low-noise biasing and optimized propagation path design to achieve 100 ns typical delay while maintaining 300 µV input offset voltage and 5 pA input bias current. The device is specified across –40°C to +125°C with 80 dB PSRR (open-drain version) and rail-to-rail input operation down to 1.65 V supply.

FAQ

What is the maximum input voltage tolerance of TLV9020DBVR relative to V–?

The TLV9020DBVR supports input voltages from –0.3 V to 6 V relative to V–, as specified in Absolute Maximum Ratings. This fault-tolerant range allows inputs to exceed V+ by up to 0.2 V or go 0.3 V below V– without damage or output inversion - critical for surviving transients in motor drive and industrial power systems. This specification is validated across –40°C to +125°C.

Can TLV9020DBVR operate from a 1.8 V supply?

Yes, TLV9020DBVR is fully specified for operation from 1.65 V to 5.5 V supply. At 1.8 V, it maintains 300 µV max input offset voltage, 100 ns propagation delay, and 16 µA quiescent current - making it suitable for battery-powered IoT sensors and low-voltage portable equipment where supply headroom is limited.

Does TLV9020DBVR require an external pull-up resistor on the OUT pin?

Yes, TLV9020DBVR has an open-drain output and requires an external pull-up resistor to establish a valid high logic level. The pull-up voltage may be set independently of V+, up to 6 V, enabling level translation between different voltage domains - for example, pulling up to 3.3 V while operating from a 1.8 V supply.

What is the thermal resistance (RθJA) of TLV9020DBVR in the DBV package?

The junction-to-ambient thermal resistance (RθJA) of TLV9020DBVR in the SOT-23 (DBV) package is 223.7 °C/W, as measured per JEDEC JESD51-2 standard. This value assumes standard 2-layer PCB layout with 1 in² copper pour connected to V–; actual thermal performance improves with enhanced copper area or thermal vias to internal ground planes.

How does the input bias current of TLV9020DBVR affect high-impedance sensor interfaces?

With a typical input bias current of 5 pA, TLV9020DBVR introduces negligible voltage error across high-impedance sources - for example, adding only 0.5 mV error across a 100 MΩ thermistor divider. This enables precise threshold detection in applications like CO₂ sensing or RTD monitoring without additional buffering stages.
