Product details

3.3V rail supervisor with 140ms reset timeout

The TPS3703A7330DSER is a Simple Reset/Power-On Reset IC from Texas Instruments that monitors a single 3.3V supply rail. When the voltage drops below the 3.3V threshold, the active-low open-drain output asserts reset and holds it for a minimum of 140ms after the rail recovers. This 140ms timeout is long enough to let downstream regulators and oscillators settle before the processor starts code execution.

Temperature range and package constraints

The part is ROHS3 compliant.

Frequently asked questions

Is TPS3703A7330DSER active low or active high reset?

Active low. The reset output goes low when the monitored voltage falls below the threshold and stays low for the reset timeout period after recovery.

What is the reset timeout of TPS3703A7330DSER?

The reset timeout is 140ms minimum. This is the guaranteed minimum; the actual timeout may be longer depending on the internal oscillator tolerance.

When sourcing TPS3703A7330DSER, what is the closest functional second-source?

The TLV803EA29VDBZR is a Simple Reset/Power-On Reset with active-low open-drain output, but its threshold is 2.9V, not 3.3V. The TLV803ED29DBZR has a 33ms minimum reset timeout versus the 140ms of the TPS3703A7330DSER. Neither is a direct drop-in; a board redesign would be needed to change the threshold or timeout.
