Product details

The TPS3803-01MDCKREP is a Simple Reset/Power-On Reset IC from Texas Instruments, monitoring a single voltage rail with an active-low, open-drain output. The SC-70-5 package keeps the footprint small enough for dense boards.

5 µs propagation delay — fast fault response

That is fast enough to catch a core voltage brownout before the processor's internal POR circuit triggers — or before a flash write corrupts data.

ROHS3 compliant. The base product number is TPS3803. Sourced per RFQ — confirm the BOM quantity and target lead time at quote.

Surface-mount SC-70-5 (also known as SOT-353). The 5-lead package has a 0.65 mm pitch — two-layer boards break out the pins without vias.

Frequently asked questions

What is the adjustable threshold range for TPS3803-01MDCKREP?

The threshold is adjustable/selectable via external resistors. The datasheet provides the formula and typical resistor values for common rail voltages. There is no fixed internal threshold — the trip point is set by the divider ratio.

What is a cross reference or equivalent for TPS3803-01MDCKREP?

The TLV803 parts also have much longer reset timeout periods (130 ms and 33 ms minimum, respectively) versus the 5 µs propagation delay of the TPS3803. For a drop-in with adjustable threshold and full military temperature, the TPS3803-01MDCKREP is the correct choice.
