Output switch and shutdown mode — power budget control
An integrated output switch and shutdown mode let the LMT70AYFQT disconnect its output pin and drop quiescent current when the host system enters a low-power sleep state. For battery-powered loggers or duty-cycled wireless sensors, this feature avoids wasting ADC input current during idle periods. The shutdown is logic-controlled; the exact threshold and timing are in the datasheet, but the key takeaway for the BOM is that the part supports intermittent measurement without an external MOSFET to gate the output.
Active lifecycle — no LTB clock ticking
The LMT70AYFQT carries an active product status with ROHS3 compliance.
Where it fits — medical, industrial, automotive under-hood
The -55°C to 150°C temperature range and ±0.13°C accuracy target precision monitoring in medical thermometry, cold-chain storage loggers, industrial process control, and automotive under-hood fluid or exhaust temperature sensing. The analog output simplifies routing to a Σ-Δ ADC or comparator input without a digital bus, which is useful in retrofit designs where the existing controller has spare analog channels but no I²C or SPI port.
