3.1V threshold supervisor with 619ms reset timeout
The TPS3840PL31DBVRQ1: The push-pull output drives the reset line directly without an external pull-up resistor, saving one component per supervisor channel. This is the standard interface for most modern MCU reset inputs, which expect a clean logic-low pulse during power-up or brownout.
Automotive temperature range and AEC-Q100 qualification
AEC-Q100 Grade 1 qualification means the part has passed the reliability stress tests (high-temperature operating life, temperature cycling, ESD) required for production automotive ECUs. The SOT-23-5 package (SC-74A) is a compact 5-pin surface-mount footprint, 2.9 mm × 1.6 mm body. It fits into space-constrained designs like engine control modules, transmission controllers, or body electronics where board area is tight.
