TPS3808G33DBVR

TPS3808G33DBVR is the tape-and-reel SOT-23-6 ordering code for the Texas Instruments TPS3808 micro-power voltage supervisor, an orderable code on the TI part-details page. Read the G33 grade on its own row: the sense threshold is 3.07 V — the G33 denotes the 3.3 V rail class, not the trip point itself — with a threshold accuracy of 0.5 % typical, quiescent current of 2.4 µA typical at a 3.3 V supply with RESET unasserted and an open-drain RESET output, on a supply of 1.65 V to 6.5 V (the 1.65 V floor applies over 0 °C to 85 °C; the wide-temperature rows start at 1.7 V). The reset delay is programmable from 1.25 ms to 10 s through the CT pin, so one supervisor covers both fast power-on resets and long processor start-up sequences. The selection point is precision at micro-power: a 3.07 V trip with half-a-percent typical accuracy (the guaranteed limits widen over temperature, to ±1.25 % over −40 °C to +85 °C) while drawing less current than the leakage of many loads it protects. Selection advice: because the trip point is 3.07 V and not 3.30 V, check the processor’s minimum operating voltage against the reset release point before approving this grade for a 3.3 V rail; the other G grades in the family set different thresholds on the same footprint. Parameters verified against the TI TPS3808 datasheet (grade table and electrical characteristics) and the TI part-details page for this code.
