Three-rail supervisor in a single SOIC-8
It fits designs that need to sequence or protect multiple voltage domains — DSP core, I/O, and analog supplies — from a single 8-SOIC package. The reset outputs are available as both active-high and active-low signals, with a push-pull, totem-pole stage that drives CMOS logic inputs directly without an external pull-up. The minimum reset timeout of 140 ms ensures the downstream processor or FPGA holds reset long enough for all rails to stabilise after power-up.
Industrial temperature rating and package fit
Surface-mount assembly with the SOIC-8 body simplifies pick-and-place — no through-hole steps, no manual insertion. The 1.27 mm pin pitch is inspectable and reworkable with basic hot-air tools.
It can be specified into a production BOM without near-term obsolescence risk. The base product number TPS3307 covers the family, and the -33DG4 suffix identifies the specific threshold variant and package.
