Texas Instruments TLV9022DDFR

Overview

TLV9022DDFR from Texas Instruments is a dual-channel, open-drain precision comparator with 300 µV input offset voltage, 100 ns propagation delay, and rail-to-rail fault-tolerant inputs supporting ±0.2 V beyond supply rails. It operates from 1.65 V to 5.5 V and draws only 16 µA per channel, enabling low-power voltage monitoring in motor drive overcurrent detection circuits.

For engineers reviewing the TLV9022DDFR datasheet, TLV9022DDFR pinout, TLV9022DDFR application, or TLV9022DDFR equivalent, key selection criteria include open-drain output compatibility with mixed-voltage logic translation, -40°C to +125°C industrial temperature range, and fault-tolerant input operation up to 6 V independent of supply.

Technical Context

The TLV9022DDFR implements a precision comparator architecture with ESD-protected, fault-tolerant inputs capable of withstanding voltages up to 6 V without damage or phase inversion. Its open-drain output stage supports pull-up to voltages below or above V+, enabling level-shifting between 1.8 V, 3.3 V, and 5 V domains.

Designed for harsh, noisy environments, it features 5 pA input bias current, 2 pF differential input capacitance, and 80–95 dB PSRR across 1.65–5.5 V supply range - ensuring stable threshold detection under supply ripple and EMI.

FAQ

What is the maximum input voltage the TLV9022DDFR can tolerate without damage?

The TLV9022DDFR supports input voltages up to 6 V on IN+ and IN− pins regardless of V+ supply voltage - a feature enabled by internal fault-tolerant clamping. This allows direct connection to 24 V field wiring or battery packs without external protection components, provided input current is limited to ≤10 mA per pin as specified in Absolute Maximum Ratings.

Does the TLV9022DDFR support rail-to-rail input operation?

Yes, the TLV9022DDFR supports a common-mode input range from (V−) − 0.2 V to (V+) + 0.2 V across its full operating temperature range. This rail-to-rail capability enables accurate threshold detection near supply rails - for example, detecting undervoltage in a 1.8 V LDO output where the trip point is set at 1.7 V.

Can the TLV9022DDFR outputs drive a 10 kΩ pull-up resistor to 5 V while powered from 3.3 V?

Yes, the open-drain outputs of TLV9022DDFR are fully compatible with mixed-supply level translation. When V+ = 3.3 V and the output is pulled up to 5 V, the device safely sinks current without damage - a core design feature confirmed in the Functional Description section and validated by 6 V absolute maximum input/output ratings.

What is the typical propagation delay of TLV9022DDFR at 1.8 V supply?

The TLV9022DDFR maintains a typical propagation delay of 100 ns (high-to-low) at 1.8 V supply, matching its performance at 5 V. This consistent speed across the 1.65–5.5 V range is verified in Section 5.10 Switching Characteristics and enables reliable timing in battery-powered systems where supply voltage varies significantly during discharge.

How does the TLV9022DDFR handle input overvoltage conditions that exceed V+?

The TLV9022DDFR incorporates internal ESD clamps and fault-tolerant input circuitry that prevents phase inversion and damage when IN+ or IN− exceeds V+ by up to 0.2 V or reaches 6 V absolute - even with V+ = 1.65 V. This behavior is explicitly guaranteed in the Electrical Characteristics table and eliminates the need for external Schottky diodes in industrial sensor front-ends.
