The open-drain, active-low output holds the reset line asserted until the supply recovers and the adjustable timeout period expires. ## Adjustable timeout and wide temperature range The reset timeout is adjustable/selectable via an external capacitor, letting the designer match the delay to the power-up settling time of the load — useful when sequencing FPGAs or multi-rail ASICs that need a known reset pulse width. Packaged in a SOT-23-6, it occupies minimal board area and is mounted via standard surface-mount reflow. The single-voltage monitoring keeps the BOM simple — one supervisor per rail, no external passives beyond the timeout cap and a pull-up resistor on the open-drain output.","metaTitle":"TPS3808G33DBVTG4 Simple Reset/Power-On Reset IC","metaDescription":"Texas Instruments TPS3808G33DBVTG4 simple reset/power-on reset IC.

The die and electrical specifications are identical. The suffix 'G4' denotes a halogen-free lead finish per TI's green packaging initiative. Pin-for-pin compatibility holds across the two order codes."},{"question":"What is the adjustable timeout range for TPS3808G33DBVTG4?","answer":"The reset timeout is adjustable/selectable via an external capacitor. The exact range depends on the capacitor value chosen; the datasheet provides the formula to set the delay.
