Texas Instruments TLV9022QDRQ1

Overview

TLV9022QDRQ1 from Texas Instruments is an AEC-Q100 Grade 1 dual-channel automotive comparator with open-drain outputs, 300 µV input offset voltage, 100 ns propagation delay, and 16 µA per channel quiescent current across 1.65 V to 5.5 V supply. It enables precision voltage monitoring in HEV/EV powertrain and body control modules.

For engineers reviewing the TLV9022QDRQ1 datasheet, TLV9022QDRQ1 pinout, TLV9022QDRQ1 application, or TLV9022QDRQ1 equivalent, key selection criteria include its fault-tolerant inputs (–0.3 V to 6 V), Power-On Reset (POR) for deterministic startup, rail-to-rail input range exceeding supply rails, and SOIC-8 packaging for automotive-grade thermal reliability.

Technical Context

The TLV9022QDRQ1 implements a high-speed, low-power comparator architecture with internal POR circuitry that holds outputs in a known state until V_S ≥ 1.65 V, eliminating transients during power ramp-up/down. Its input stage supports common-mode voltages from (V_–) – 0.2 V to (V₊) + 0.2 V and features ESD clamps enabling 6 V fault tolerance without phase inversion.

Each channel delivers 100 ns propagation delay at 5 V with 15 pF load and maintains <±0.3 mV offset over temperature (–40°C to +125°C). The open-drain output supports pull-up to voltages beyond V₊, enabling level translation between 1.8 V logic and 5 V systems.

FAQ

What is the maximum input voltage the TLV9022QDRQ1 can tolerate without damage?

The TLV9022QDRQ1 supports input voltages from –0.3 V to 6 V on both IN+ and IN– pins, independent of the supply rails. This fault-tolerant capability allows direct connection to 12 V battery lines or LIN bus signals without external clamping diodes, and is validated per AEC-Q100 stress testing protocols.

Does the TLV9022QDRQ1 have built-in Power-On Reset functionality?

Yes, the TLV9022QDRQ1 integrates a Power-On Reset (POR) circuit that holds both outputs in a known state until the supply voltage reaches the minimum operating level (1.65 V). This prevents output glitches during power ramp-up and ensures deterministic behavior in automotive microcontroller interfaces.

Can the TLV9022QDRQ1 operate from a 1.8 V supply?

Yes, the TLV9022QDRQ1 operates across 1.65 V to 5.5 V supply range. At 1.8 V, it maintains 100 ns propagation delay (high-to-low), ±0.3 mV typical input offset, and 16 µA per channel quiescent current - enabling compatibility with modern low-voltage automotive MCUs and sensors.

What is the purpose of the exposed thermal pad on the TLV9022QDRQ1 SOIC package?

The exposed thermal pad on the TLV9022QDRQ1's SOIC-8 package must be connected directly to the V– (ground) pin. This improves thermal dissipation and reduces junction-to-board thermal resistance to 111.2°C/W, supporting reliable operation at +125°C ambient in engine bay applications.

How does the TLV9022QDRQ1 differ from the TLV9032QDRQ1?

The TLV9022QDRQ1 features open-drain outputs, while TLV9032QDRQ1 uses push-pull outputs. TLV9022QDRQ1 supports pull-up to voltages beyond V+, enabling level translation; TLV9032QDRQ1 can source/sink >90 mA but lacks that flexibility. Both share identical offset, speed, and power specs.
