The LM71QCIMF/NOPB carries AEC-Q100 qualification under the Automotive series designation, with a full -40°C to 150°C operating temperature range. That temperature grade — grade 0 — covers the underhood and engine-bay locations where ambient soaks above 105°C are routine. The 13-bit SPI digital output (0.0625 °C per LSB) eliminates analog routing and external ADC cost — the host MCU reads the temperature register over a standard SPI frame.
Accuracy band and the shutdown mode for sleep-state compliance
For a thermal-derating calculation on a power module or a battery-management temperature trip, the worst-case spread sets the guard band — not the typical figure. A shutdown mode is available on the part, dropping the quiescent current to near-zero for battery-off or CAN-sleep states. The sensor wakes and completes a conversion before the host SPI transaction starts — no external enable FET needed.
Package, supply, and ROHS3 compliance for BOM integration
The SOT-23-5 (SC-74A) package is a 5-pin small outline with no exposed pad — a standard footprint that routes on a two-layer board without thermal-via planning. ROHS3 compliant per the lifecycle record — no exempt substances, so the part fits a RoHS BOM without a waiver.
