Product details

1.8V threshold supervisor for automotive rails

This is a single-channel voltage supervisor with a fixed 1.8V threshold — it monitors a 1.8V supply rail and asserts a reset output when the rail drops below that threshold. The output is Active Low, open-drain, so it can be wire-ORed with other reset signals on the bus.

AEC-Q100 qualification and package details

The TPS3703A5180DSERQ1 is AEC-Q100 qualified, which is a non-negotiable requirement for production automotive BOMs. The 6-WSON package (1.5x1.5 mm body) is a small footprint suitable for space-constrained ECU or sensor module PCBs. Store the reels in a dry cabinet if the moisture sensitivity level (MSL) rating is above 1; check the TI datasheet for the exact MSL rating.

The base product number is TPS3703; the full order code includes the threshold voltage (5180 = 1.8V) and the package suffix (DSERQ1 = 6-WSON, Tape & Reel). Verify the BOM line matches this exact suffix before committing.

Frequently asked questions

Is TPS3703A5180DSERQ1 AEC-Q100 qualified?

Yes, it is part of the Automotive, AEC-Q100 series, which means it has passed the automotive-grade reliability tests required for production vehicle electronics.

Does TPS3703A5180DSERQ1 require external resistors for voltage monitoring?

No — the 1.8V threshold is fixed internally. No external resistor divider is needed to set the trip point. The open-drain output requires a pull-up resistor to the logic supply rail.
