DIGI VRM IC Introduction
• ASP1000 and ASP1101 are all DIGI power controller, all
BIOS setting function can transmit signals through
SMBUS to change or adjust IC internal value and in
order to get all DIGI VRM function.

Repairing For NO VCORE
When the debug card shows 00, the CPU or sequence can’t run
completely.
(1) Visually inspect: (wrong parts, components missing …)
(2) Measure the impedance (component solder on the board)
A. The impedance of each power circuit is short with GND or not.
B. Each MOS, the impedance of the H-S or L-S MOS GS side is K level,
C. the impedance of DS side can’t be zero
D. Compare the difference with a golden compare .
(3) Power on and check each voltage

72.

How To Identify MOS Is Normal
Step 1:
Multi-meter in Ω level : “+” side connects with Source, “-” side connects with
Gate. Let MOSFET going into the cut-off state.
Step 2:
Multi-meter in diode level : “+” side connects with Source, “-” side connects
with drain, measure Vf: 0.3V ~ 0.6V
Step 3:
Multi-meter in resistance level :
“+” side connects with drain, “-” side connects with source Value: xM Ω, ~ ∞ Ω,
“+” side connects with drain, “-” side connects with gate Value: xM Ω, ~ ∞ Ω
“+” side connects with source, “-” side connects with gate Value: xM Ω, ~ ∞ Ω
Step 4:
Multi-meter in resistance level :
“+” side connects with gate, “-” side connects with source ,to turn on MOSFET
“+” side connects with drain, “-” side connects with source Value: 0Ω ~~ 10 Ω
