COMPONENT DESCRIPTION
Intersil Corporation, Dual Power Controller
N-Channel MOSFET in 8 SOIC or equivalent replacement
Mounting areas for additional 8 SOIC , DPAK or D 2 PAK packaged
MOSFETs
100m ?, 1 %, Metal Strip current sensing resistor
20m ?, 1 %, Metal Strip current sensing resistor
20 ? , Resistor in series with gate capacitor. This RC may be necessary
to provide current loop stability. Keep resistor < 50 ? .
10k ? , Current limit = ~10 μ A x (R ILIM / R SENSE ).
Add resistor (<50 ? ) to isolate V DD from load transients if necessary to
eliminate random V DD low reset. Cut short to install.
0.01 μ F, 10 μ A charging I source provides slow ramp on of N-Channel
MOSFETs
0.1 μ F, Charge Pump Capacitor necessary for +12V and +5V
operation.
0.047 μ F, Provides ~9ms of time-out period prior to latch off during
which IOC can be resolved. The duration of current limit time-out (in
seconds) = 200k ? x C TIM (Farads).
0.1 μ F, Provides V DD decoupling
See Table 3 for jumper configuration descriptions
Lit indicates a fault condition
Tie point for dedicated +12V HIP1012 supply, use in default
configuration
Modify edge connector finger lengths for power sequencing
Switch and load resistor pair to invoke high current load on 5V
Switch and load resistor pair to invoke low current load on 5V
Switch and load resistor pair to invoke high current load on 3.3V
Switch and load resistor pair to invoke low current load on 3.3V
Lit indicates N-Channel MOSFETs are on and loads are HOT
