Texas Instruments TLC3702QPWRQ1

Overview

TLC3702QPWRQ1 from Texas Instruments is a dual micropower LinCMOS™ voltage comparator designed for automotive powertrain signal conditioning. It delivers 2.7 µs typical propagation delay (tPLH) with 5-mV overdrive, 100 µW typical supply power at 5 V, and operates from 3 V to 16 V - enabling direct connection to 12-V battery systems in transmission control units.

For engineers reviewing the TLC3702QPWRQ1 datasheet, TLC3702QPWRQ1 pinout, TLC3702QPWRQ1 application, or TLC3702QPWRQ1 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification (–40°C to +125°C), push-pull CMOS output driving capacitive loads without pullup resistors, and input offset voltage ≤5 mV (typ) with ±2000-V HBM ESD rating.

Technical Context

The TLC3702QPWRQ1 implements two independent comparators using TI's LinCMOS™ process, delivering high input impedance (>10¹² Ω), ultra-low input bias current (5 pA typ at 25°C), and stable input offset voltage (≤10 mV max over full temperature range). Its push-pull CMOS output stage eliminates external pullup resistors while sourcing/sinking ±8 mA per channel.

It supports single-supply operation from 3 V to 16 V with common-mode input range extending to VDD −1.5 V at full temperature range, and achieves 84 dB typical CMRR and 85 dB typical kSVR - critical for noise-immune sensing in engine control and braking circuits.

FAQ

What is the maximum supply voltage rating for TLC3702QPWRQ1?

The absolute maximum supply voltage for TLC3702QPWRQ1 is 18 V, though recommended operating range is 3 V to 16 V. This 16-V upper limit allows direct integration into 12-V automotive battery systems including start-stop and load-dump scenarios. Exceeding 18 V risks permanent damage per Absolute Maximum Ratings. The device maintains full functionality across its entire 3–16 V operating window, with stable propagation delay and offset performance verified down to 4 V per datasheet Section 6.3.

Does TLC3702QPWRQ1 require external pullup resistors on its outputs?

No, TLC3702QPWRQ1 does not require external pullup resistors because it features a push-pull CMOS output stage capable of sourcing and sinking ±8 mA per channel. This architecture directly drives capacitive loads up to 50 pF while achieving 2.7 µs typical tPLH - eliminating board space, BOM cost, and power loss associated with pullup resistors. The output is fully compatible with TTL and CMOS logic families, and its rail-to-rail swing simplifies interfacing with microcontrollers in automotive modules.

What AEC-Q100 test results apply to TLC3702QPWRQ1?

TLC3702QPWRQ1 is qualified to AEC-Q100 Grade 1 with device temperature range −40°C to +125°C ambient, Human-Body Model (HBM) ESD rating ±2000 V, and Charged-Device Model (CDM) ESD rating ±750 V on pins 1/4/5/8. These results are documented in the official TI datasheet SGLS156F and confirm suitability for under-hood automotive applications including transmission control, braking, and engine management systems where thermal and electrostatic robustness are mandatory.

How does the LinCMOS™ process benefit TLC3702QPWRQ1 performance?

The LinCMOS™ process enables TLC3702QPWRQ1 to achieve ultra-low input bias current (5 pA typ), high input impedance (>10¹² Ω), and stable input offset voltage (≤5 mV typ) across temperature - all while maintaining CMOS power efficiency. Unlike standard CMOS, LinCMOS optimizes analog characteristics such as CMRR (84 dB typ) and kSVR (85 dB typ), making TLC3702QPWRQ1 highly immune to supply noise and common-mode interference in noisy automotive environments.

Can TLC3702QPWRQ1 operate with inputs outside the supply rails?

TLC3702QPWRQ1 inputs may exceed the supply rails only if current is externally limited to ±5 mA, as specified in Absolute Maximum Ratings. While the device incorporates TI-patented ESD protection that clamps overvoltage, operation outside the common-mode range (0 V to VDD −1.5 V) compromises output state accuracy and channel isolation. For reliable function, inputs must remain within the recommended common-mode range - especially during power-up/power-down sequences in engine control applications.
