Product details

Automotive voltage monitor with AEC-Q100 qualification

The TPS3703B3080DSERQ1 is a single-channel voltage monitor from Texas Instruments, qualified to the Automotive AEC-Q100 standard. It monitors a single supply rail with a threshold of 0.8V and asserts an active-low, open-drain reset output when the monitored voltage drops below that threshold. The reset stays low for a minimum of 14ms after the supply recovers, ensuring the rail is stable before the system restarts — a critical timing parameter for automotive modules that must sequence power-on cleanly.

Housed in a 6-WFDFN package with supplier device package 6-WSON measuring 1.5x1.5 mm.

Available in Tape & Reel and Cut Tape options for surface-mount assembly.

Frequently asked questions

Is TPS3703B3080DSERQ1 equivalent to TPS3703B3080DSER?
