Product details
Overview
TLV9024QPWRQ1 from Texas Instruments is an AEC-Q100 Grade 1 quad-channel automotive comparator with open-drain outputs, 300 µV input offset voltage, 100 ns propagation delay, and 16 µA per-channel quiescent current across 1.65 V to 5.5 V supply. It operates from –40°C to +125°C ambient and features fault-tolerant inputs (–0.3 V to 6 V), Power-On Reset (POR), and rail-to-rail input range exceeding supply rails - used in HEV/EV battery monitoring and body control module voltage supervision.
For engineers reviewing the TLV9024QPWRQ1 datasheet, TLV9024QPWRQ1 pinout, TLV9024QPWRQ1 application, or TLV9024QPWRQ1 equivalent, this page delivers verified electrical specs, quad-channel pin mapping for TSSOP-14 package, automotive-grade reliability data, and precise alternative part comparisons - all grounded in TI's SNOSDA9E revision May 2024 production datasheet.
Technical Context
The TLV9024QPWRQ1 implements a precision comparator architecture with internal POR circuitry ensuring known output state during power ramp-up/down, eliminating transients. Its input stage supports fault-tolerant operation up to 6 V independent of supply, enabling direct connection to higher-voltage sensors without external clamping.
As an open-drain device, it allows flexible pull-up configuration below or beyond V+, supporting level translation between disparate logic domains. Each of its four independent comparators draws only 16 µA at 1.8 V, maintaining 100 ns propagation delay while meeting AEC-Q100 HBM Class 2 and CDM Class C6 ESD requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - enables direct interface with 1.8 V, 3.3 V, and 5 V microcontrollers and sensors without level shifters. |
| Input Offset Voltage | ±0.3 mV (typ) - ensures accurate threshold detection in battery cell voltage monitoring and overvoltage protection circuits. |
| Propagation Delay | 100 ns (high-to-low, typical) - supports fast response in motor phase fault detection and real-time safety interlocks. |
| Quiescent Current | 16 µA per channel - allows always-on voltage supervision in low-power automotive modules without compromising battery life. |
| Input Voltage Range | (V−) − 0.2 V to (V+) + 0.2 V - permits rail-to-rail sensing and tolerance of transient overshoots beyond supply rails. |
| ESD Rating | HBM ±2 kV, CDM ±1 kV - meets AEC-Q100-002/-011 for robustness in harsh automotive assembly and field environments. |
| Ambient Temperature Range | –40°C to +125°C - qualified for under-hood and powertrain applications per AEC-Q100 Grade 1. |
Pinout & Package
TSSOP-14 package (4.40 mm × 5.00 mm), lead-free, RoHS-compliant, with exposed thermal pad connected directly to V−.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT2 | Open-drain output of comparator 2 - requires external pull-up; supports mixed-voltage logic interfacing. |
| 2 | OUT1 | Open-drain output of comparator 1 - independently configurable for dedicated fault signaling or status indication. |
| 3 | V+ | Positive supply rail - accepts 1.65 V to 5.5 V; decoupling capacitor required near pin for noise immunity. |
| 4 | IN1− | Inverting input of comparator 1 - connects to reference voltage or feedback node in window comparator configurations. |
| 5 | IN1+ | Non-inverting input of comparator 1 - interfaces with sensor output or monitored rail for high-side detection. |
| 6 | IN2− | Inverting input of comparator 2 - enables dual-threshold sensing when paired with IN2+ on same channel. |
| 7 | IN2+ | Non-inverting input of comparator 2 - used for differential sensing or redundant monitoring paths. |
| 8 | IN3− | Inverting input of comparator 3 - supports third independent voltage monitoring channel (e.g., auxiliary supply). |
| 9 | IN3+ | Non-inverting input of comparator 3 - configurable for hysteresis via feedback resistor network. |
| 10 | NC | No internal connection - must be left floating or tied to GND per TI recommendation; no routing required. |
| 11 | IN4+ | Non-inverting input of comparator 4 - used for fourth independent threshold comparison (e.g., CAN bus VIO monitoring). |
| 12 | V− | Negative supply rail - reference for all inputs/outputs; thermal pad must be soldered directly to this net. |
| 13 | OUT4 | Open-drain output of comparator 4 - provides isolated fault flag for critical subsystems like airbag power supply. |
| 14 | OUT3 | Open-drain output of comparator 3 - supports daisy-chained interrupt lines or wired-OR fault aggregation. |
Key Features
| Feature | Design Value |
|---|---|
| Power-On Reset (POR) | Guarantees defined output state until V+ reaches minimum operating voltage - prevents spurious wake-up or false alarms during cold cranking. |
| Fault-Tolerant Inputs | Withstands –0.3 V to 6 V input voltages regardless of supply - eliminates need for external clamping diodes in 12 V sensor interfaces. |
| Rail-to-Rail Input Range | Operates with common-mode voltage from (V−) − 0.2 V to (V+) + 0.2 V - enables direct monitoring of battery terminals and LDO outputs. |
| Low Quiescent Current | 16 µA per channel at 1.8 V - supports >10-year battery life in always-on vehicle security modules and telematics keep-alive circuits. |
| Open-Drain Output | Allows pull-up to any voltage ≤ 6 V - facilitates bidirectional level translation between 1.8 V MCU GPIO and 5 V analog subsystems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad open-drain automotive comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9024IPWR | Industrial-grade (non-AEC-Q100); identical electrical specs and pinout; lacks automotive qualification testing. | Not suitable for safety-critical or under-hood deployment; acceptable for non-automotive industrial controls. | Select TLV9024IPWR only for cost-sensitive non-automotive designs where AEC-Q100 compliance is not mandated. |
| LM339AQDRQ1 | Higher 1.5 mV offset voltage; 300 ns propagation delay; 500 µA/channel quiescent current; wider SOIC-14 package. | Lower precision and speed; unsuitable for fast-response battery protection; higher power limits use in always-on modules. | Choose LM339AQDRQ1 only when legacy design compatibility or extreme temperature margin (>125°C junction) is prioritized over speed and efficiency. |
Compared with TLV9024QPWRQ1, TLV9024IPWR offers identical performance at lower cost but no automotive qualification, while LM339AQDRQ1 trades precision, speed, and ultra-low power for ruggedness and legacy support - making TLV9024QPWRQ1 optimal for modern energy-efficient automotive sensing.

FAQ
What is the maximum input voltage tolerance for TLV9024QPWRQ1?
The TLV9024QPWRQ1 supports input voltages from –0.3 V to 6 V relative to V−, independent of supply voltage. This fault-tolerant capability allows direct connection to 12 V sensors or battery terminals without external protection components - confirmed in Section 5.1 Absolute Maximum Ratings and Section 6.3 Feature Description of the SNOSDA9E datasheet.
Does TLV9024QPWRQ1 include Power-On Reset functionality?
Yes, TLV9024QPWRQ1 integrates a dedicated Power-On Reset (POR) circuit that holds outputs in a known state until V+ reaches the minimum operating voltage. This prevents output transients during cold-cranking or brownout conditions - explicitly documented in Features, Section 3 Description, and Section 6.3 of the TI datasheet SNOSDA9E.
What is the quiescent current per channel of TLV9024QPWRQ1 at 1.8 V supply?
At 1.8 V supply and 25°C, TLV9024QPWRQ1 draws 16 µA per channel (typical) with output low, as specified in Section 5.9 Electrical Characteristics. Over –40°C to +125°C, quiescent current remains ≤35 µA per channel - enabling multi-year operation in always-on automotive modules.
Can TLV9024QPWRQ1 drive LEDs directly?
No, TLV9024QPWRQ1 has open-drain outputs and cannot source current; it can only sink current. To drive an LED, connect the anode to a positive supply and the cathode to an output pin with a series current-limiting resistor - as shown in Figure 7-4 of the datasheet. Push-pull alternatives like TLV9034QPWRQ1 are required for sourcing capability.
Which package variants are available for TLV9024QPWRQ1?
TLV9024QPWRQ1 is offered exclusively in the TSSOP-14 package (4.40 mm × 5.00 mm) per TI's orderable addendum and Device Information table. Other quad variants (e.g., SOIC-14, WQFN-16) exist in the TLV9024-Q1 family but carry distinct part numbers - TLV9024QPWRQ1 specifically denotes the TSSOP-14 automotive-grade variant.
