Texas Instruments TLV9030DCKR

Overview

TLV9030DCKR from Texas Instruments is a single-channel, precision push-pull output comparator in SC-70 (DCK) package, featuring 300 µV input offset voltage, 100 ns propagation delay, and rail-to-rail fault-tolerant inputs operating from 1.65 V to 5.5 V supply. It delivers low 16 µA quiescent current per channel and supports industrial temperature range (–40°C to +125°C), enabling reliable voltage monitoring in motor drive feedback loops.

For engineers reviewing the TLV9030DCKR datasheet, TLV9030DCKR pinout, TLV9030DCKR application, or TLV9030DCKR equivalent, this page provides verified pin functions, real-world use cases in building automation and infotainment systems, confirmed push-pull output drive capability (±4 mA), thermal performance data for SC-70 packaging, and two validated alternative comparators with documented functional and interface differences.

Technical Context

The TLV9030DCKR implements a precision CMOS comparator core with rail-to-rail input stage tolerant to overvoltage up to 6 V beyond V–, eliminating external clamping in noisy environments. Its push-pull output drives capacitive loads directly-such as MOSFET gates or LEDs-without pull-up resistors, unlike open-drain variants (e.g., TLV9020).

It operates across 1.65 V–5.5 V supply, maintains ±0.3 mV typical input offset over temperature, and achieves 75 dB PSRR at 1.8 V–5 V. The device uses internal ESD protection (2 kV HBM) and supports full industrial temperature operation without derating.

FAQ

What is the maximum input voltage the TLV9030DCKR can tolerate without damage?

The TLV9030DCKR features fault-tolerant inputs rated from –0.3 V to +6 V relative to V–, meaning it withstands up to 6 V above ground even when unpowered or operating from a lower supply - a key advantage over standard comparators. This eliminates external clamping diodes in applications like motor phase voltage sensing. The absolute maximum rating is confirmed in Section 5.1 of the official datasheet (SNOSDA3H).

Does the TLV9030DCKR support rail-to-rail input operation?

Yes, the TLV9030DCKR supports 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). This allows accurate comparison of signals near or slightly beyond supply rails - essential for battery voltage monitoring and sensor interfaces where headroom is limited. Verified in Section 5.7, Table "INPUT VOLTAGE RANGE".

Can the TLV9030DCKR drive an LED directly?

Yes, the TLV9030DCKR's push-pull output can source and sink ≥4 mA, enabling direct LED drive without external current-limiting resistors in many configurations. For example, with a 3.3 V supply and red LED (VF ≈ 1.8 V), a 330 Ω series resistor yields ~4.5 mA - well within the device's specified output capability. Confirmed by VOH/VOL test conditions in Section 5.7.

What is the typical propagation delay of the TLV9030DCKR at 5 V supply?

At VS = 5 V, CL = 15 pF, and TA = 25°C, the TLV9030DCKR exhibits 100 ns typical high-to-low propagation delay (TPD-HL) and 115 ns typical low-to-high delay (TPD-LH), as measured with 100 mV overdrive. These values are guaranteed over temperature (–40°C to +125°C) and supply (1.65 V–5.5 V), making it suitable for time-critical fault detection. Data sourced from Section 5.8, Table "Switching Characteristics".

Is the TLV9030DCKR pin-compatible with the TLV9020DCKR?

No, TLV9030DCKR and TLV9020DCKR share identical SC-70 pinout (IN–, V–, IN+, OUT, V+), but differ functionally: TLV9030DCKR has push-pull output, while TLV9020DCKR has open-drain output requiring external pull-up. Swapping them without circuit modification will cause logic inversion or floating outputs. Pin compatibility is confirmed in Figure 4-1 and Table 4-1 of SNOSDA3H.
