The reset timeout is adjustable via an external capacitor, letting the designer tailor the power-up delay to the specific load capacitance and regulator ramp rate without adding a separate timer IC. ## Threshold, temperature, and package considerations for the BOM The 0.4V threshold is unusually low — most simple reset ICs monitor rails at 0.6V to 4.6V. This part is aimed at sub-1V core supplies (e.g., 0.8V or 0.9V DDR memory VTT) where a 0.6V threshold would never trip. At 125°C junction the leakage on the open-drain output rises, so pull-up resistor values above 100 kΩ may not guarantee a clean logic-high — keep the pull-up in the 10 kΩ–47 kΩ range for this grade. The pad is electrically connected to the die substrate (typically GND), so the PCB copper pour under the part serves both as a heat sink and a low-impedance ground connection.","metaTitle":"TPS3850H01DRCT Texas Instruments Simple Reset/Power-On","metaDescription":"TPS3850H01DRCT by TI: Simple Reset/Power-On Reset, Active Low, Open Drain output, 0.4V threshold, adjustable timeout, -40°C to 125°C, 10-VSON.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Open Drain or Open Collector","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"Adjustable/Selectable","Package / Case":"10-VFDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3850","Voltage - Threshold":"0.4V","Operating Temperature":"-40°C~125°C(TJ)","Supplier Device Package":"10-VSON (3x3)","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.2300","priceTiers":[{"qty":1,"price":"$3.23000","currency":"USD"},{"qty":10,"price":"$2.90400","currency":"USD"},{"qty":25,"price":"$2.74520","currency":"USD"},{"qty":100,"price":"$2.37910","currency":"USD"},{"qty":250,"price":"$2.25712","currency":"USD"},{"qty":500,"price":"$2.02530","currency":"USD"},{"qty":1250,"price":"$1.72650","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/bc290ea6dc9188b1fefd6210f8765b60.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3850H01DRCT/alternatives.json"},"ai":{"faq":[{"question":"Is TPS3850H01DRCT a direct replacement for TLV803EA29VDBZR?","answer":"No. The TLV803EA29VDBZR has a fixed 2.93V threshold and a 130 ms minimum reset timeout, while the TPS3850H01DRCT uses a 0.4V threshold with an adjustable timeout.
