Product details
Overview
TLV9022QDDFRQ1 from Texas Instruments is an AEC-Q100 Grade 1 dual-channel automotive precision 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) and Power-On Reset for reliable startup in HEV/EV powertrain monitoring.
For engineers reviewing the TLV9022QDDFRQ1 datasheet, TLV9022QDDFRQ1 pinout, TLV9022QDDFRQ1 application, or TLV9022QDDFRQ1 equivalent, key selection considerations include its open-drain output architecture, rail-to-rail input range exceeding supply rails, AEC-Q100 qualification, low-power high-speed trade-off, and compatibility with 1.8 V logic interfaces in automotive body control modules.
Technical Context
The TLV9022QDDFRQ1 implements a precision comparator core with internal biasing and Power-On Reset (POR) circuitry that forces output into a known high-impedance state until VS ≥ 1.65 V, eliminating spurious transitions during power ramp-up/down. Its input stage supports common-mode voltages from (V–) – 0.2 V to (V+) + 0.2 V and tolerates up to 6 V without damage or phase inversion.
As an open-drain device, TLV9022QDDFRQ1 requires external pull-up for logic-level translation - compatible with pull-up voltages below or above V+ - and delivers 4 mA sink capability at ≤125 mV above V– (25°C). Input bias current is 5 pA typical, enabling high-impedance sensing in battery voltage monitors and sensor threshold detection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - supports direct interface with 1.8 V, 3.3 V, and 5 V microcontrollers and sensors in automotive domains. |
| Input Offset Voltage | ±0.3 mV (typ) - enables accurate voltage window detection in battery cell monitoring and overvoltage protection circuits. |
| Propagation Delay | 100 ns (typ, high-to-low) - provides fast response for real-time fault detection in motor control and DC-DC converter supervision. |
| Quiescent Current | 16 µA per channel - allows always-on operation in low-power wake-up comparators for body electronics and infotainment standby modes. |
| Input Common-Mode Range | (V–) – 0.2 V to (V+) + 0.2 V - permits direct connection to signals beyond supply rails, e.g., CAN bus voltage levels or sensor outputs in noisy environments. |

| Ambient Temperature Range | –40°C to +125°C - qualified for under-hood and powertrain applications including HEV/EV inverters and battery management systems. |
Pinout & Package
TLV9022QDDFRQ1 is housed in an 8-pin DDF (SOT-23-THN) package measuring 1.60 mm × 2.90 mm, with exposed thermal pad connected directly to V–.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT1 | Open-drain output of comparator 1 | Requires external pull-up; sinks up to 4 mA; compatible with mixed-voltage logic translation (e.g., 1.8 V MCU sensing 5 V rail). |
| IN1– | Inverting input of comparator 1 | High-impedance node (5 pA bias current); accepts signals up to 6 V regardless of supply - ideal for direct sensor interfacing. |
| IN1+ | Non-inverting input of comparator 1 | Same fault-tolerant specification as IN1–; used for reference-based threshold comparison in voltage supervisors. |
| V– | Negative supply terminal | Reference ground for all inputs/outputs; thermal pad must be soldered to PCB ground plane for thermal and EMI performance. |
| IN2+ | Non-inverting input of comparator 2 | Dedicated second channel for independent monitoring tasks - e.g., dual battery cell voltage comparison. |
| IN2– | Inverting input of comparator 2 | Electrically identical to IN1–; supports simultaneous differential sensing or redundant fault checking. |
| OUT2 | Open-drain output of comparator 2 | Independent output with same drive strength and logic flexibility as OUT1; enables dual-alert signaling without external logic. |
| V+ | Positive supply terminal | Accepts 1.65–5.5 V; PSRR >80 dB ensures stable operation amid supply ripple in automotive 12 V systems. |
Key Features
| Feature | Design Value |
|---|---|
| Power-On Reset (POR) | Guarantees known high-Z output state until VS reaches minimum operating voltage - prevents false triggers during cold cranking or ignition sequencing. |
| Fault-Tolerant Inputs | Withstands –0.3 V to 6 V input voltages without damage or output inversion - eliminates need for external clamping diodes in harsh automotive environments. |
| Rail-to-Rail Input Range | Operates with inputs extending 0.2 V beyond V+ and V– - enables direct monitoring of battery terminals, CAN transceivers, or sensor outputs without level-shifting. |
| Low Quiescent Current | 16 µA per channel at 1.8 V - supports multi-year battery life in always-on vehicle security and telematics wake-up circuits. |
| AEC-Q100 Grade 1 Qualification | Validated for –40°C to +125°C ambient operation with HBM Class 2 and CDM Class C6 - meets OEM requirements for powertrain and body control modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual open-drain automotive comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9022QDRQ1 | Same electrical specs; packaged in SOIC-8 (3.91 mm × 4.90 mm) instead of DDF (1.60 mm × 2.90 mm). | SOIC-8 offers easier manual soldering and higher thermal mass but occupies ~5× more PCB area than DDF. | Select TLV9022QDRQ1 for prototyping, legacy board compatibility, or thermal-heavy applications where footprint is secondary. |
| LM7322QMA/NOPB | Higher quiescent current (1.3 mA vs. 16 µA), no POR, wider supply (2.7–36 V), push-pull output only - not open-drain. | Designed for high-speed op-amp use cases; lacks fault-tolerant inputs and AEC-Q100 Grade 1 temperature rating. | Choose LM7322QMA/NOPB only if driving capacitive loads directly or requiring rail-to-rail output swing - not for low-power or AEC-Q100-compliant designs. |
Compared with TLV9022QDRQ1, TLV9022QDDFRQ1 delivers identical performance in a space-constrained DDF package ideal for modern automotive ECUs, while LM7322QMA/NOPB trades ultra-low power and automotive qualification for higher drive strength and broader supply range - making it unsuitable as a drop-in replacement.

FAQ
What is the maximum input voltage the TLV9022QDDFRQ1 can tolerate without damage?
The TLV9022QDDFRQ1 supports input voltages from –0.3 V to 6 V relative to V–, independent of supply voltage. This fault-tolerant input structure allows direct connection to signals exceeding the supply rails - such as CAN bus lines or battery terminals - without external protection components. The specification is validated per AEC-Q100 stress testing and applies across the full –40°C to +125°C temperature range.
Does the TLV9022QDDFRQ1 have built-in Power-On Reset (POR), and how does it affect system startup?
Yes, TLV9022QDDFRQ1 integrates a dedicated Power-On Reset circuit that holds both outputs in a high-impedance state until the supply voltage reaches ≥1.65 V. This prevents undefined or transient output states during power ramp-up or brownout conditions - critical for avoiding false alarms in battery monitors or unintended actuation in BCMs. The POR is active across the full automotive temperature range and requires no external components.
Can the TLV9022QDDFRQ1 drive a 10 kΩ pull-up resistor to 3.3 V while powered from 1.8 V?
Yes, TLV9022QDDFRQ1's open-drain output is fully compatible with mixed-voltage logic translation. When powered from 1.8 V, it can reliably sink current through a 10 kΩ pull-up to 3.3 V - delivering >330 µA of sink current with <125 mV voltage drop above V– at 25°C. This enables seamless interface between low-voltage MCUs and higher-voltage subsystems without level shifters.
How does the TLV9022QDDFRQ1's input offset voltage drift with temperature?
The TLV9022QDDFRQ1 exhibits ±0.5 µV/°C maximum input offset voltage drift over –40°C to +125°C. At 25°C, typical offset is ±0.3 mV; worst-case drift adds ±60 µV over the full range. This stability supports precision threshold detection in automotive applications like coolant temperature window monitoring or brake fluid level sensing where drift-induced false triggers must be minimized.
Is the TLV9022QDDFRQ1 pin-compatible with other devices in the TLV902x-Q1 family?
No - TLV9022QDDFRQ1 uses the DDF (SOT-23-THN) 8-pin package with a unique pinout optimized for thermal performance and small footprint. It is not pin-compatible with SOIC-8 (TLV9022QDRQ1), VSSOP-8 (TLV9022QDGKRQ1), or WSON-8 variants. Engineers must verify layout compatibility when substituting packages, though electrical specifications remain consistent across the family.
