PS10/PS11

A051204

The following waveforms demonstrate the sequencing of

the PWRGD flags:

PWRGD Timing (PS11)

Test conditions: VIN = 48V, CRAMP = 10nF,

RTB = 118k, RTC = 59k, and RTD = 46.4k.

PWRGD Timing (Minimum Delays)

Test conditions: VIN = 48V, CRAMP = 10nF, RTB = 3.24k,

RTC = 3.24k, RTD = 3.24k, RPULL-UP = 47k.

PWRGD Timing (Maximum Delays)

Test conditions: VIN = 48V, CRAMP = 10nF, RTB = 118k,

RTC = 118k, RTD = 118k, RPULL-UP = 47k.

PS11 Power Down Sequence after UVOFF

Test conditions: CRAMP = 10nF, RTB = 3.24k, RTC = 3.24k,

RTD = 3.24k, RPULL-UP = 47k, CPWRGD_B = 0.47

µF, CPWRGD_C

= 0.94

µF, CPWRGD_D = 1.41µF, VUVOFF = 33.4V, the as-

sumed brick turn-off threshold is 2.7V min TTL logic high.
