Product details

Supervisor IC for processor power monitoring

The TLV803SDBZR: The open-drain active-low output holds the reset line low for a minimum of 120ms after the monitored voltage rises above the threshold, giving the processor time to stabilize before release.

Threshold, timeout, and temperature range

The 2.93V threshold is suited for monitoring 3.0V or 3.3V rails — the reset asserts before the supply falls below the processor's minimum operating voltage, preventing undefined logic states.

SOT-23-3 package and sourcing

Housed in a 3-pin SOT-23-3 package, the TLV803SDBZR occupies minimal board area and is compatible with standard surface-mount assembly processes.

Frequently asked questions

What is the closest functional second-source to the TLV803SDBZR?

The TL7702BID also operates over a -40°C to 85°C range, narrower than the TLV803SDBZR's 125°C rating. These differences mean the two parts are not drop-in replacements without board-level changes.
