The reset output is both active-high and active-low, driven by a push-pull totem-pole stage — no external pull-up resistor needed. This covers both processor reset polarities from a single device. ## SOT-23-5 footprint and industrial temperature range Housed in a SOT-23-5 package (SC-74A, SOT-753), surface-mount only. The single-voltage monitor is a dedicated supervisor — no extra channels, no watchdog. For a 1.8 V rail, this is the right threshold; for other voltages, the TPS3124 family offers variants with different trip points.
