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.
