Product details

8.5V threshold supervisor for 12V/9V rails

The TPS3847085DBVR is a Texas Instruments Simple Reset/Power-On Reset IC that monitors a single voltage rail and asserts a reset when the supply drops below 8.5V. The active-low, push-pull output drives the reset line directly without an external pull-up resistor. The 4.5ms typical reset timeout gives the supply time to recover from short dips while still catching genuine brownouts.

SOT-23-5 package and active lifecycle

It ships in a SOT-23-5 package, surface-mount, available in tape-and-reel or cut-tape options.

Frequently asked questions

Is the TPS3847085DBVR active low or high?

The reset output is active low. The output goes low when the monitored voltage falls below the 8.5V threshold and releases (goes high) after the 4.5ms typical timeout once the supply recovers.

What package does the TPS3847085DBVR come in?

It is supplied in an SOT-23-5 (SC-74A) surface-mount package, also referred to as the supplier device package SOT-23-5. Available in tape-and-reel or cut-tape formats.

Is the TPS3847085DBVR RoHS compliant?

Yes, it is ROHS3 compliant.
