What this automotive reset IC does
The reset output is push-pull, totem pole — no external pull-up resistor needed.
Automotive-grade temperature range and qualification
That means it has passed extended reliability testing for high-temperature operation, temperature cycling, and ESD robustness — suitable for under-hood, engine bay, or chassis-domain electronics where a commercial-grade reset IC would not survive.
Package and footprint — SOT-23-5
Housed in a 5-pin SOT-23-5 (SC-74A) package, the TPS3823-30QDBVRQ1 is a surface-mount part with a 0.95mm pitch — hand-solderable with a fine-tip iron and a steady hand. The small footprint frees up board space in dense automotive ECU layouts. The supplier device package is SOT-23-5, and the case code is SC-74A.
For existing BOM lines or repair stock, the only sourcing path is through the independent market — surplus inventory, new-old-stock, or broker channels. No official successor part is listed by TI for this exact order code.
