Product details
Overview
LMT01ELPGMQ1 from Texas Instruments is an AEC-Q100 Grade 0 qualified 2-pin digital output temperature sensor with pulse-count interface, delivering ±0.5°C max accuracy from –20°C to 90°C, 0.0625°C resolution per pulse, and continuous 104-ms update rate over –40°C to +150°C. It operates with 2.0 V to 5.5 V floating supply (VP–VN), consumes only 34 µA during conversion, and interfaces directly to MCU GPIO or comparator inputs for battery management and engine control sensing.
For engineers reviewing the LMT01ELPGMQ1 datasheet, LMT01ELPGMQ1 pinout, LMT01ELPGMQ1 application, or LMT01ELPGMQ1 equivalent, this page delivers verified technical context, real-world timing behavior, confirmed package dimensions, validated pulse-to-temperature mapping, and precise ESD/thermal specs required for automotive-grade thermal monitoring in noisy environments.
Technical Context
The LMT01ELPGMQ1 uses a thermal diode front-end feeding a sigma-delta ADC referenced to an internal voltage regulator, producing a proportional current pulse train (34 µA low / 125 µA high) at ~88 kHz. Its output is not voltage-based but current-loop encoded - each pulse represents 0.0625°C, with total count ranging from 15 to 3228 pulses across –40°C to 150°C.
It requires no external clock, ADC, or calibration: the pulse count is read by gating a counter on a fixed time window (e.g., 10 ms), then applying linear interpolation from the TO-92/LPG-specific Pulse Count to Temperature LUT. The device remains in low-current state (<34 µA) for ≤54 ms after power-on before initiating transmission.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-pin digital temperature sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM71QIMF/NOPB | Voltage-output (10-bit SPI), 3-pin SOT-23, ±1.5°C accuracy, 1.8–5.5 V supply | Requires SPI interface and external pull-up; less EMI robust than current-loop pulse output | Choose when existing design already uses SPI peripherals and lower cost outweighs accuracy/robustness trade-off |
| STS4030-DIS-B | I²C output, 2.1–5.5 V, ±0.2°C accuracy, 1.5 mm × 1.5 mm DFN, no AEC-Q100 grade | Higher accuracy but lacks automotive qualification and current-loop noise immunity | Prefer for consumer-grade portable devices where board space is critical and EMI is minimal |
Compared with LM71QIMF/NOPB and STS4030-DIS-B, the LMT01ELPGMQ1 uniquely combines AEC-Q100 Grade 0 qualification, 2-pin simplicity, current-mode EMI resilience, and factory-calibrated ±0.5°C accuracy - making it the only drop-in solution for safety-critical automotive thermal monitoring where wiring harness noise and under-hood temperature extremes dominate design constraints.

FAQ
What is the operating temperature range of the LMT01ELPGMQ1?
The LMT01ELPGMQ1 is rated for –40°C to +150°C free-air operation per AEC-Q100 Grade 0 qualification. Its highest accuracy (±0.5°C) is guaranteed from –20°C to 90°C; accuracy degrades gradually to ±0.75°C at 150°C. Operation beyond 150°C risks permanent damage and is not supported. The LMT01ELPGMQ1 maintains full functionality across this range without external compensation.
How does the LMT01ELPGMQ1 interface with a microcontroller?
The LMT01ELPGMQ1 interfaces via a 2-pin current pulse train: VP and VN form a floating loop where current toggles between 34 µA (low) and 125 µA (high) at ~88 kHz. A series resistor (e.g., 10 kΩ) converts pulses to 0.34–1.25 V logic-compatible voltage swings readable by any GPIO input with timer capture or a comparator. No ADC, clock, or protocol stack is needed - the LMT01ELPGMQ1 handles all signal conditioning internally.
Is the LMT01ELPGMQ1 pin-compatible with other LMT01 variants?
Yes - the LMT01ELPGMQ1 shares identical TO-92 (LPG) pinout and electrical behavior with LMT01QLPG and LMT01QDQX (WSON), differing only in AEC-Q100 grade and package. All LMT01 variants use VP/VN terminals with identical pulse-count transfer function, timing, and supply requirements. However, WSON variants have different thermal metrics and are rated to 125°C only - the LMT01ELPGMQ1 is the only variant qualified to 150°C in TO-92.
What is the minimum wire length supported for remote sensing with the LMT01ELPGMQ1?
The LMT01ELPGMQ1 supports up to 2 meters of wire length in two-wire probe configurations, validated under EMI-prone conditions. Stray capacitance from long traces affects rise/fall times but not pulse count integrity due to its current-mode interface. For 2 m runs, use twisted-pair wiring and keep VP/VN impedance balanced; a 10 kΩ pull-up resistor remains effective. The LMT01ELPGMQ1's integrated EMI suppression ensures reliable counting even with induced noise.
Does the LMT01ELPGMQ1 require calibration during system production?
No - the LMT01ELPGMQ1 is factory calibrated and requires zero system-level calibration or software compensation. Its ±0.5°C accuracy from –20°C to 90°C is guaranteed over life and temperature without trimming. Linear interpolation from the provided TO-92/LPG Pulse Count to Temperature LUT achieves full spec performance; no lookup table adjustment or curve-fitting is needed. This eliminates production test steps and firmware overhead for the LMT01ELPGMQ1.
