Texas Instruments TLV9030QDBVRQ1

Overview

TLV9030QDBVRQ1 from Texas Instruments is a single-channel, automotive-grade precision comparator with push-pull output, 300 µV input offset voltage, 100 ns propagation delay, and rail-to-rail fault-tolerant inputs supporting up to 6 V beyond supply rails - used for battery voltage monitoring and overvoltage protection in motor drive control circuits.

For engineers reviewing the TLV9030QDBVRQ1 datasheet, TLV9030QDBVRQ1 pinout, TLV9030QDBVRQ1 application, or TLV9030QDBVRQ1 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, 16 µA per-channel quiescent current at 1.65–5.5 V supply, and push-pull output capable of sourcing/sinking >4 mA for direct LED or MOSFET gate driving in harsh industrial environments.

Technical Context

The TLV9030QDBVRQ1 implements a high-speed, low-power comparator core with internal ESD clamps enabling ±2 kV HBM robustness and fault-tolerant inputs that remain functional even when driven 0.2 V below V− or 0.2 V above V+, eliminating external level-shifting in mixed-supply systems. Its push-pull architecture avoids external pull-up resistors and supports bidirectional logic interfacing.

Designed for automotive and industrial applications requiring stable performance across –40°C to +125°C, the device features 75 dB PSRR (push-pull), 60 dB CMRR at 1.8 V, and <0.5 µV/°C offset drift - enabling precise threshold detection in noisy power-supply monitoring and safety-critical sensor signal conditioning.

FAQ

What is the maximum input voltage the TLV9030QDBVRQ1 can tolerate relative to its supply rails?

The TLV9030QDBVRQ1 features fault-tolerant inputs rated from (V−) – 0.3 V to 6 V, meaning it withstands inputs up to 6 V regardless of supply voltage - e.g., a 12 V sensor signal can be applied directly while powered from 3.3 V, provided current is limited to ≤10 mA per input pin. This capability is confirmed in Section 5.1 Absolute Maximum Ratings and Figure 4-1 of the datasheet.

Does the TLV9030QDBVRQ1 support rail-to-rail input common-mode voltage range?

Yes, the TLV9030QDBVRQ1 supports a rail-to-rail input common-mode range from (V−) – 0.2 V to (V+) + 0.2 V across its full operating temperature range (–40°C to +125°C), as specified in Table 5-7 Electrical Characteristics. This allows direct interfacing with sensors or DACs operating at the same supply rails without attenuation or level shifting.

What is the typical propagation delay of the TLV9030QDBVRQ1, and how does it vary with load?

The TLV9030QDBVRQ1 has a typical high-to-low propagation delay of 100 ns and low-to-high delay of 115 ns at 5 V supply, CL = 15 pF, and VID = ±100 mV (Section 5.8). Delay increases slightly with capacitive load - e.g., at 50 pF, TPD-HL rises to ~115 ns - but remains stable across temperature and supply voltage due to its robust push-pull output stage.

Is the TLV9030QDBVRQ1 pin-compatible with other devices in the TLV90x0 family?

Yes, TLV9030QDBVRQ1 shares the TLV90x0 standard South East pinout (IN+, IN−, OUT, V−, V+) with TLV9020QDBVRQ1 and TLV9030QDCKRQ1 in DBV and DCK packages. However, TLV9020 uses open-drain output and requires an external pull-up, so direct substitution affects logic polarity and timing - verify output configuration before replacement.

What packaging and marking information is associated with TLV9030QDBVRQ1?

TLV9030QDBVRQ1 is supplied in a 5-pin SOT-23 (DBV) package with dimensions 1.60 mm × 2.90 mm. The top-marking consists of "A9" followed by a 2-digit date code and factory traceability symbol, per TI's standard SOT-23 marking convention for automotive-grade devices. No exposed thermal pad is present in this variant.
