The 2.93V threshold is set for monitoring a 3.3V nominal supply rail. When the monitored voltage falls below 2.93V, the reset output goes active low and holds for a minimum of 60ms after the supply recovers above the threshold. This 60ms timeout gives the regulated supply time to stabilise before the supervised device is released from reset — long enough for most linear regulators and DC-DC converters to settle after a brownout or battery swap. The push-pull output eliminates the external pull-up resistor that an open-drain supervisor would need, saving one component per rail and simplifying the BOM for dense boards. The active-low polarity matches the reset input of the majority of ARM Cortex-M and other MCUs. The TPS3620-33MDGKREP is supplied in an 8-VSSOP package (also listed as 8-TSSOP, 8-MSOP with 0.118-inch body width, 3.00mm width).","metaTitle":"TPS3620-33MDGKREP Battery Backup Circuit, 2.93V Threshold","metaDescription":"Texas Instruments TPS3620-33MDGKREP battery backup circuit with 2.93V threshold, active-low push-pull reset, 60ms timeout.
