Product details

Active production — sourcing posture for the TPS3103E15DBVT

The TPS3103E15DBVT is a Texas Instruments Simple Reset/Power-On Reset supervisor with an Active Low, Open Drain output. It monitors a single voltage rail at a 1.434V threshold and asserts reset for a minimum of 65ms after the supply rises above that threshold.

The 1.434V threshold is the trip point at which the reset output de-asserts. For a 1.5V or 1.8V core rail, this threshold sits about 0.07V below the nominal supply — tight enough to catch a brownout before the logic fails.

Package and temperature range — fit for industrial and commercial boards

Lifecycle and compliance — no end-of-life concern

Frequently asked questions

Is the TPS3103E15DBVT equivalent to the TPS3103E18DBVT?

The TPS3103E18DBVT is the same base part (TPS3103) with a different threshold voltage — 1.8V versus the 1.434V of the variant. The pinout, package, and reset timeout are identical, but the threshold voltage is not adjustable. Select the variant that matches your monitored rail voltage.

What is the closest functional second-source to the TPS3103E15DBVT?

The TLV803EA29VDBZR and TLV803ED29DBZR are similar Simple Reset/Power-On Reset supervisors from Texas Instruments with Active Low, Open Drain outputs. However, their threshold voltages are 2.93V, not 1.434V, and their reset timeouts differ (130ms and 33ms minimum, respectively). They are not drop-in replacements for the TPS3103E15DBVT.
