The open-drain output allows wired-OR connection with other fault signals. Typical application is reset generation for microcontrollers, DSPs, or ASICs in automotive ECUs, ADAS modules, and body-control units. ## Threshold and timeout for supply sequencing With a voltage threshold of 3.3V, this supervisor monitors a nominal 3.3V rail. That 140ms window is longer than the TLV803EA29VDBZR's 130ms minimum, which can matter if the upstream regulator has a slow soft-start ramp. The part is ROHS3 compliant. Date-code spread and packaging condition are confirmed at quote time.","metaTitle":"TPS3870J4330DSERQ1 Texas Instruments Automotive Supervisor","metaDescription":"Texas Instruments TPS3870J4330DSERQ1 Simple Reset/Power-On Reset, 3.3V threshold, active-low open-drain output, -40°C to 125°C, 6-WSON.
