Pin Function
Power-Good Output 2: Asserted when the following is true: (PWRGD1 = Asserted)
AND (Time after Assertion of PWRGD1 = Time PWRGD2, as programmed by the
capacitor on PGTIMER). Once PWRGD1 is asserted, the PGTIMER pin begins to
charge and PWRGD2 will assert when PGTIMER crosses the PWRGD2 threshold
(V
/Power-Good Output 2: Asserted when the following is true: (/PWRGD1 = Asserted)
AND (Time after Assertion of /PWRGD1 = Time /PWRGD2, as programmed by the
capacitor on PGTIMER). Once /PWRGD1 is asserted, the PGTIMER pin begins to
charge and /PWRGD2 will assert when PGTIMER crosses the /PWRGD2 threshold
(V
Power-Good Output 3: Asserted when the following is true: (PWRGD1 = Asserted)
AND (Time after Assertion of PWRGD1 = Time PWRGD3, as programmed by the
capacitor on PGTIMER). Once PWRGD1 is asserted, the PGTIMER pin begins to
charge and PWRGD3 will assert when PGTIMER crosses the PWRGD3 threshold

/Power-Good Output 3: Open Collector. Asserted when the following is true:
(/PWRGD1 = Asserted) AND (Time after Assertion of /PWRGD1 = Time /PWRGD3,
as programmed by the capacitor on PGTIMER). Once /PWRGD1 is asserted, the
PGTIMER pin begins to charge and /PWRGD3 will assert when PGTIMER crosses
the /PWRGD3 threshold (V
