SLVSCJ5B December 2015 – June 2020 TPS7H3301-SP
PRODUCTION DATA.
The TPS7H3301-SP provides an open-drain PGOOD output that goes high when the VTT/VO output is within 20% of VTTREF (typ). PGOOD deasserts within 1 μs after the output exceeds the size of the power-good window. During initial VTT/VO startup, PGOOD asserts high 2 ms (typ) after the VTT/VO enters power-good window. Because PGOOD is an open-drain output, a 100-kΩ pullup resistor between PGOOD and a stable active supply voltage rail is required.
