Texas Instruments TLV9024PWR

Overview

TLV9024PWR from Texas Instruments is a quad-channel, open-drain output precision comparator with rail-to-rail fault-tolerant inputs, 300μV max input offset voltage, 100ns typical propagation delay, and 16μA per-channel quiescent current across 1.65V–5.5V supply. It operates from –40°C to +125°C and is used in motor drive overvoltage detection and industrial sensor threshold monitoring.

For engineers reviewing the TLV9024PWR datasheet, TLV9024PWR pinout, TLV9024PWR application, or TLV9024PWR equivalent, key selection criteria include open-drain output compatibility with mixed-voltage logic interfaces, ±0.3mV offset stability over temperature, fault-tolerant input operation up to 6V beyond V–, and SOIC-14 package suitability for high-density industrial PCBs.

Technical Context

The TLV9024PWR implements a precision comparator core with ESD-hardened, fault-tolerant input stage enabling safe operation when inputs exceed V+ or fall below V– by up to 0.3V-critical for noisy factory automation signals. Its open-drain output supports flexible pull-up to voltages independent of V+, enabling level translation between 1.8V logic and 5V systems.

Each of the four comparators features independent input bias current ≤5pA and common-mode input range extending 0.2V beyond both supply rails. The device uses internal clamping and snapback ESD protection (2kV HBM) without phase inversion during overvoltage transients on IN+ or IN–.

FAQ

What is the maximum input voltage the TLV9024PWR can tolerate without damage?

The TLV9024PWR inputs (IN+ and IN–) are fault-tolerant up to 6V relative to V–, even when V+ is as low as 1.65V. This allows direct connection to unregulated 5V or 12V rails without external protection components. Absolute maximum rating is –0.3V to 6V on input pins, verified per TI's SNOSDA3H datasheet Section 5.1.

Does the TLV9024PWR support rail-to-rail input operation?

Yes, the TLV9024PWR supports a common-mode input voltage range from (V–) – 0.2V to (V+) + 0.2V across its full operating temperature range (–40°C to +125°C). This enables direct interfacing with sensors, DACs, and battery terminals without level-shifting circuitry.

Can multiple TLV9024PWR open-drain outputs be wire-OR'd together?

Yes - all four open-drain outputs (OUT1–OUT4) of the TLV9024PWR can be connected to a shared pull-up resistor and node. This is commonly used for aggregated fault signaling (e.g., "any channel tripped" flag) and is electrically validated in TI's application notes for industrial monitoring systems.

What is the typical quiescent current per channel of the TLV9024PWR at 1.8V supply?

The TLV9024PWR draws 16μA per channel typical at 1.8V supply and 25°C, rising to ≤35μA per channel across –40°C to +125°C. This value is confirmed in Section 5.9 of the SNOSDA3H datasheet under "Quiescent current per comparator" test conditions.

Is the TLV9024PWR pin-compatible with other devices in the TLV902x family?

No - the TLV9024PWR (SOIC-14) is not pin-compatible with TLV9022 (8-pin) or TLV9020/TLV9021 (5-pin). However, its SOIC-14 pinout matches the TLV9034PWR (push-pull version), allowing layout reuse when output topology changes are acceptable.
