The reset outputs are available in both active-high and active-low push-pull configurations, giving the designer flexibility to interface with different processor reset schemes without external inverters. ## 140 ms reset timeout for sequenced power-up This avoids spurious boot failures on systems where the core rail stabilises before the I/O rail. The 8-HVSSOP package with exposed pad helps conduct heat to the PCB ground plane, keeping the die temperature within the operating range even in enclosed enclosures.","metaTitle":"TPS3305-18DGNRG4 Multi-Voltage Supervisor","metaDescription":"Texas Instruments TPS3305-18DGNRG4 multi-voltage supervisor monitors two rails at 1.68V and 2.93V.
