Texas Instruments TLV9024QDYYRQ1

Overview

TLV9024QDYYRQ1 from Texas Instruments is a quad-channel, open-drain output precision comparator with rail-to-rail fault-tolerant inputs, 300 µV max input offset voltage, 100 ns typical propagation delay, and 16 µA per-channel quiescent current at 1.65–5.5 V supply. It operates across –40°C to +125°C and is used in motor drive overvoltage detection and factory automation voltage monitoring circuits.

For engineers reviewing the TLV9024QDYYRQ1 datasheet, TLV9024QDYYRQ1 pinout, TLV9024QDYYRQ1 application, or TLV9024QDYYRQ1 equivalent, key selection criteria include open-drain output compatibility with mixed-voltage logic interfaces, ±0.3 mV offset stability over temperature, fault-tolerant input operation up to 6 V beyond V–, and quad-channel integration for compact voltage window detection.

Technical Context

The TLV9024QDYYRQ1 implements a high-speed, low-power comparator architecture with ESD-protected, fault-tolerant inputs capable of withstanding –0.3 V to 6 V relative to V– without phase inversion or damage. Its open-drain output supports flexible pull-up configurations below or above V+, enabling level translation between 1.8 V, 3.3 V, and 5 V domains.

Each of the four comparators features independent rail-to-rail input stages, 5 pA typical input bias current, and 2 pF differential input capacitance - optimized for low-noise, high-impedance sensing in industrial control feedback loops and battery-monitoring systems.

FAQ

What is the maximum input voltage the TLV9024QDYYRQ1 can tolerate on its IN+ and IN– pins?

The TLV9024QDYYRQ1 supports input voltages from –0.3 V to 6 V relative to V–, independent of the V+ supply voltage. This fault-tolerant range allows direct connection to 24 V field signals without external clamping diodes or resistive dividers - a key advantage over standard comparators limited to the V+–V– range. This specification is validated across the full –40°C to +125°C temperature range.

Does the TLV9024QDYYRQ1 support rail-to-rail input operation?

Yes, the TLV9024QDYYRQ1 features true rail-to-rail input capability, with a common-mode input voltage range specified from V– – 0.2 V to V+ + 0.2 V. This enables accurate comparison of signals near the supply rails - such as battery voltage monitoring at end-of-discharge or sensor outputs referenced to V+ - without signal attenuation or error introduced by input stage limitations.

What is the typical quiescent current consumption of the TLV9024QDYYRQ1 per channel?

The TLV9024QDYYRQ1 draws 16 µA per channel under typical conditions (V_S = 1.8 V or 5 V, no load, output low), with a maximum of 35 µA per channel across the full –40°C to +125°C temperature range. This ultra-low current enables always-on voltage supervision in battery-powered equipment, where four channels consume less than 65 µA total - extending operational life in energy-constrained applications.

Can the TLV9024QDYYRQ1 outputs drive LEDs directly?

No - the TLV9024QDYYRQ1 has open-drain outputs that can only sink current; they cannot source current. To drive an LED, connect the anode to a positive supply (e.g., 3.3 V or 5 V) and the cathode to an output pin, with a series current-limiting resistor. The device supports sinking up to 4 mA with <125 mV drop at 25°C, making it suitable for indicator LEDs but not high-brightness or high-current loads.

Is the TLV9024QDYYRQ1 pin-compatible with other devices in the TLV902x family?

TLV9024QDYYRQ1 uses the 14-pin SOT-23 (DYY) package, which is unique to this variant. It is not pin-compatible with TLV9024DR (SOIC-14), TLV9024PW (TSSOP-14), or TLV9024RUC (X2QFN-14), as pin assignments differ across packages. Engineers must consult Table 4-3 in the datasheet for exact pin mapping - especially noting that GND is pin 11 in DYY, whereas it is pin 12 in SOIC and pin 11 in X2QFN.
