Texas Instruments TLV9024DYYR

Overview

TLV9024DYYR from Texas Instruments is a quad-channel precision comparator with open-drain outputs, rail-to-rail fault-tolerant inputs (–0.2 V to 5.7 V), 300 µV max input offset voltage, and 100 ns typical propagation delay. It operates from 1.65 V to 5.5 V supply and draws only 16 µA per channel, enabling low-power voltage monitoring in motor drive overcurrent detection circuits.

For engineers reviewing the TLV9024DYYR datasheet, TLV9024DYYR pinout, TLV9024DYYR application, or TLV9024DYYR equivalent, key selection criteria include its open-drain output architecture, –40°C to +125°C industrial temperature range, fault-tolerant input capability up to 6 V, and compatibility with low-voltage logic translation and level-shifting designs.

Technical Context

The TLV9024DYYR implements a precision comparator core with differential input stage optimized for low offset drift (±0.5 µV/°C) and high common-mode rejection (60–70 dB). Its open-drain output supports flexible pull-up configurations-below, at, or above V+-enabling bidirectional level translation without external components.

Input fault tolerance is achieved via internal clamping diodes and snapback ESD structures, allowing inputs to safely exceed V+ by up to 0.2 V or go 0.3 V below V– without phase inversion or damage. The device's 2 pF differential input capacitance and 5 pA bias current support high-impedance sensing in noisy industrial environments.

FAQ

What is the maximum input voltage allowed on IN+ and IN– pins of TLV9024DYYR?

The TLV9024DYYR supports input voltages from (V–) – 0.3 V to 6 V on both IN+ and IN– pins, independent of the supply voltage. This fault-tolerant range allows safe operation even when inputs exceed V+ by up to 0.2 V or go below V–, eliminating external clamping diodes in noisy motor drive applications.

Does TLV9024DYYR support rail-to-rail input operation?

Yes, TLV9024DYYR features true rail-to-rail input common-mode range: from (V–) – 0.2 V to (V+) + 0.2 V. This enables direct comparison of signals referenced to ground or floating supplies-such as shunt amplifier outputs or battery monitor voltages-without attenuation or level shifting.

Can TLV9024DYYR outputs drive LEDs directly?

No-TLV9024DYYR has open-drain outputs and cannot source current. To drive an LED, connect the anode to a positive supply (e.g., 3.3 V) and the cathode to an OUTx pin; the LED illuminates when the comparator asserts low. A current-limiting resistor must be used, and sinking capability is rated for 4 mA at 125 mV drop.

What is the thermal pad connection requirement for TLV9024DYYR?

The exposed thermal pad on TLV9024DYYR must be soldered directly to the V– (GND) plane. This connection provides critical thermal conduction and improves EMI immunity. Leaving the pad unconnected or floating degrades junction temperature rise and may cause parametric drift or reliability issues in continuous operation.

How does TLV9024DYYR differ from TLV9034 in pinout and functionality?

TLV9024DYYR uses open-drain outputs and shares identical pinout with TLV9034DYYR (quad push-pull), but output behavior differs fundamentally: TLV9024DYYR requires external pull-ups and supports wired-OR logic, while TLV9034 can actively drive high. They are not pin-compatible replacements due to incompatible output architectures.
