The open-drain output lets you wire-OR the reset signal with other supervisors or a manual reset button — a common trick on multi-rail boards where one supervisor handles the core and another handles the I/O rail. Housed in a SOT-23-5 (SC-74A) package, the part is surface-mount and fits a compact footprint — easy to route on two-layer PCBs.","metaTitle":"TPS3828-50DBVTG4 Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3828-50DBVTG4 simple reset IC with 4.55V threshold, active-low open-drain output, 120ms timeout.
