This means one BOM line covers multiple rail voltages — set the trip for 3.3 V on one build, 5.0 V on the next — without changing the IC. The timeout is set with a capacitor on the CT pin, giving the designer control over how long the reset stays asserted after the rail recovers. ## Temperature range and package for tight spots The 6-pin SON package (1.45 mm x 1 mm body) saves board area but demands a well-designed solder stencil and a thermal via under the exposed pad to keep the junction within limits at high ambient. For a BOM that needs a voltage supervisor for the next several years, this part does not force a last-time-buy decision today.","metaTitle":"TPS3897ADRYT Simple Reset/Power-On Reset, Active High","metaDescription":"Texas Instruments TPS3897ADRYT simple reset/power-on reset IC.
