Product details
Overview
TLV1702AQDGKRQ1 from Texas Instruments is a dual-channel automotive-grade microPower comparator with rail-to-rail inputs, open-collector outputs, 55 µA per channel quiescent current, 560 ns low propagation delay (low-to-high), and operation across –40°C to +125°C. It enables precise voltage monitoring in high-side sensing and window comparator topologies for battery management and power supply supervision.
For engineers reviewing the TLV1702AQDGKRQ1 datasheet, TLV1702AQDGKRQ1 pinout, TLV1702AQDGKRQ1 application, or TLV1702AQDGKRQ1 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, ±1.1 V to ±18 V dual-supply capability, 300 µV typical input offset voltage, and 36 V output pull-up tolerance independent of supply voltage.
Technical Context
The TLV1702AQDGKRQ1 implements a rail-to-rail input stage that prevents phase inversion when inputs exceed supply rails, enabling robust operation in noisy or overvoltage-prone environments. Its open-collector output supports wired-OR configurations and level-shifting up to 36 V above the negative supply-critical for automotive battery-sensing applications where output must interface with higher-voltage logic or relay drivers.
Designed for low-power systems, it maintains stable propagation delay (±200 ns variation) over temperature (–40°C to +125°C) and supply (2.2 V to 36 V), with input bias current ≤15 nA at 25°C and ≤20 nA across full temperature range-ensuring minimal loading on high-impedance sensor nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |

IC Role / Device Role / Timing Role: Two channels monitor independent rails; outputs feed OR-gated fault signal to system watchdog. Use Value: 2.2 V minimum supply allows operation during brown-out; 55 µA current minimizes impact on auxiliary 3.3 V rail. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel open-collector comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC3702-Q1 | Push-pull output (no external pull-up needed); higher 20 µA quiescent current; 20 mA output drive. | Preferred where logic-level compatibility with 3.3 V/5 V microcontrollers is required without external components. | Select TLC3702-Q1 when board space is constrained and no 24 V interface is needed; avoid if 36 V output swing or ultra-low IQ is critical. |
| TLV3702-Q1 | 560 nA quiescent current (100× lower); rail-to-rail input; push-pull output; 16 V max supply. | Better suited for ultra-low-power battery sensors but incompatible with 24 V/36 V automotive battery monitoring. | Choose TLV3702-Q1 only for sub-µA standby systems with ≤16 V supply; TLV1702AQDGKRQ1 remains optimal for full 12 V/24 V automotive voltage ranges. |
Compared with TLC3702-Q1 and TLV3702-Q1, TLV1702AQDGKRQ1 uniquely balances 36 V operation, AEC-Q100 Grade 1 qualification, and 55 µA quiescent current-making it the only dual comparator qualified for direct integration into high-voltage automotive power domain monitoring without external level-shifting or regulation.

FAQ
What is the maximum supply voltage rating for TLV1702AQDGKRQ1?
The absolute maximum supply voltage for TLV1702AQDGKRQ1 is 40 V (±20 V), but the recommended operating range is 2.2 V to 36 V (±1.1 V to ±18 V). Operation beyond 36 V risks exceeding electrical specifications and may degrade long-term reliability. The device is commonly used at 12 V or 24 V in automotive applications, with headroom for load dump transients up to 36 V.
Does TLV1702AQDGKRQ1 support dual-supply operation?
Yes, TLV1702AQDGKRQ1 supports true dual-supply operation from ±1.1 V to ±18 V. When configured with V+ = +12 V and V– = –12 V, the input common-mode range extends from –12 V to +12 V, enabling bipolar signal detection such as AC zero-crossing in motor control feedback loops. The open-collector outputs remain referenced to V–, allowing pull-up to any voltage ≤36 V above V–.
What is the input offset voltage specification for TLV1702AQDGKRQ1 over temperature?
TLV1702AQDGKRQ1 has a maximum input offset voltage of ±5.5 mV over the full operating temperature range of –40°C to +125°C. At 25°C and 36 V supply, typical offset is ±300 µV, with drift of ±4 µV/°C to ±20 µV/°C. This performance enables accurate threshold setting in battery voltage monitors where 10 mV error corresponds to <0.1% error at 12 V nominal.
Can TLV1702AQDGKRQ1 drive a 24 V relay directly?
Yes, TLV1702AQDGKRQ1 can drive a 24 V relay directly via its open-collector output: connect the relay coil between +24 V and the OUT pin, with the other coil terminal grounded. The output sinks up to 20 mA continuously and tolerates up to 36 V above V–, making it compatible with standard 24 V automotive relays. No level-shifter or transistor buffer is required.
Is TLV1702AQDGKRQ1 pin-compatible with other TLV170x-Q1 variants?
No, TLV1702AQDGKRQ1 is not pin-compatible with TLV1701-Q1 (SOT-23-5/SC-70-5) or TLV1704-Q1 (TSSOP-14). It uses the VSSOP-8 (DGK) package with dedicated dual-channel pinout: Pins 1/7 are outputs, Pins 2/3/6/8 are inputs, and Pins 4/5 are supplies. Migration requires PCB layout change; however, functional behavior and reference designs are consistent across the TLV170x-Q1 family.
