Edge6420
Application Information
One application for the Edge6420 is to provide necessary
DC voltages and currents for 4 channels of pin electronics
(driver, receiver, load) and per pin measurement units.
For example, using the:
Edge720 Load / Driver / Comparator
Edge4707 PPMU
with the following specifications:
Edge720
–1.5 < driver output high < +7.5V
–1.5 < driver output low
< +7.5V
–1.5 < comparator threshold high < +7.5V
–1.5 < comparator threshold low
< +7.5V
–1.5 < commutating voltage < 7.5V
0 < load source current <
24 mA
0 < load sink current < 24 mA
Edge 4707 PPMU
–2.8 < PPMU (MI) compare high voltage < +2.8V
–2.8 < PPMU (MI) compare low voltage < +2.8V
–3.0 < PPMU (FV) < +14.0V
Other
0 < flash programming voltage (VHH) < +14V
Table 8 demonstrates Edge6420 settings that can be
used to fulfill the above requirements.
Power Supplies (for this application):
15.25
≤ AVCC ≤ 15.75V
–4.75V
≤ VEE ≤ –4.25V
4.6V
≤ AVDD ≤ 5.25V
4.85
≤ DVDD ≤ 5.15V
AGND = 0, SGND = 0
