The active-low, open-drain output asserts a reset when either monitored voltage drops below its threshold, and holds the reset for a minimum of 70 ms after both rails recover. ## Thresholds and temperature range The 1.68V threshold suits a nominal 1.8V rail with a 120 mV undervoltage margin; the 2.93V threshold suits a 3.3V rail with a 370 mV margin. The 8-pin footprint is shared with the standard MSOP-8 and TSSOP-8 land pattern.","metaTitle":"TPS3306-18DGKR Multi-Voltage Supervisor","metaDescription":"Texas Instruments TPS3306-18DGKR multi-voltage supervisor monitors two rails at 1.68V and 2.93V thresholds.
