Product details
Overview
LM60QIM3/NOPB from Texas Instruments is an AEC-Q100 Grade 1 automotive-qualified analog temperature sensor in SOT-23 (DBZ) package, delivering linear 6.25 mV/°C output with 424 mV offset across −40°C to +125°C ambient range, ±4°C max accuracy over full range, and 70 μA max quiescent current (new chip). It enables single-supply negative-temperature sensing in battery-powered ECUs and power modules.
For engineers reviewing the LM60QIM3/NOPB datasheet, LM60QIM3/NOPB pinout, LM60QIM3/NOPB application, or LM60QIM3/NOPB equivalent, key selection criteria include automotive-grade thermal accuracy, low self-heating (<0.1°C in still air), SOT-23 footprint compatibility, and direct analog interface without ADC reference or negative rail.
Technical Context
The LM60QIM3/NOPB implements a bipolar silicon bandgap-based sensing element with emitter-follower output stage, producing a ratiometric voltage output defined by VO = (6.25 mV/°C × T) + 424 mV. Its DC output impedance is typ. 120 Ω / max. 800 Ω, supporting direct connection to 12-bit SAR ADCs with minimal loading error.
It operates from 2.7 V to 10 V with no digital interface or configuration-only analog voltage output-and requires no external calibration. Shutdown is achieved by disabling the supply, leveraging intrinsic ultra-low power consumption (≤70 μA) for logic-gate-driven power gating in automotive subsystems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog temperature sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM60CIM3X/NOPB | Same SOT-23 package and 6.25 mV/°C gain, but rated for ±4°C accuracy over −40°C to +125°C without AEC-Q100 qualification | Not qualified for automotive safety-critical systems; limited to industrial or consumer use | Select when AEC-Q100 compliance is not required and cost optimization is prioritized |
| TMP235DBZT | Higher accuracy (±0.5°C at 25°C), same SOT-23 package, but 10 mV/°C gain and no 424 mV offset - requires ADC reference adjustment | Superior precision for cabin temperature sensing; lacks built-in offset for seamless negative-temperature support | Select when higher accuracy outweighs need for offset-enabled single-supply operation |
Compared with LM60CIM3X/NOPB, LM60QIM3/NOPB adds AEC-Q100 Grade 1 validation and functional safety documentation; compared with TMP235DBZT, it trades absolute accuracy for integrated offset and automotive qualification-enabling simpler, safer, and more robust integration in ECU thermal monitoring.

FAQ
What is the guaranteed accuracy of LM60QIM3/NOPB over its full operating temperature range?
The LM60QIM3/NOPB is specified for ±4°C maximum accuracy across the full −40°C to +125°C ambient operating range, per AEC-Q100 Grade 1 requirements. This accuracy includes initial calibration error, temperature coefficient drift, and long-term stability over 1000 hours at 125°C. At 25°C, accuracy improves to ±3°C maximum.
Does LM60QIM3/NOPB require external calibration or trimming for automotive applications?
No, LM60QIM3/NOPB is factory-calibrated and requires no external calibration or trimming. Its linear transfer function VO = (6.25 mV/°C × T) + 424 mV is fully characterized and verified across temperature, supply, and process variations per AEC-Q100 test plans. System-level calibration is unnecessary for standard implementations.
Can LM60QIM3/NOPB be powered directly from a microcontroller GPIO pin?
Yes, LM60QIM3/NOPB's maximum quiescent current of 70 μA (new chip) allows direct powering from most MCU GPIO pins capable of sourcing ≥100 μA. This enables hardware-controlled on/off cycling for ultra-low-power thermal polling in automotive sleep modes without additional PMIC circuitry.
What is the thermal response time of LM60QIM3/NOPB in still air on a standard PCB?
When mounted on a 0.5-inch square 2-oz copper PCB (per TI test setup), the LM60QIM3/NOPB exhibits a thermal time constant of approximately 60 seconds in still air for the new chip variant. This represents the time to reach 63% of final temperature under step-change conditions and is consistent with its SOT-23 package mass and thermal coupling to the board.
How does the LM60QIM3/NOPB handle capacitive loads on its VOUT pin?
The LM60QIM3/NOPB can drive up to 10 nF capacitive load directly without oscillation or settling degradation, thanks to its emitter-follower output stage and 800 Ω max output impedance. For larger capacitances (>10 nF), a series resistor may be needed to maintain stability, and TI recommends adding a 1 μF capacitor from VOUT to GND only in noisy environments to form a 199 Hz low-pass filter.
