Auxiliary Supplies - Switch On-Resistance
over operating free-air temperature range (unless otherwise noted)
PARAMETER
TEST CONDITIONS
R_ON,DVCC
On-resistance of switch
between DVCC and VDSYS
I_LOAD = I_CORE + I_IO = 10 mA + 10 mA = 20 mA
R_ON,DAUX1
On-resistance of switch
between AUX1 and VDSYS
I_LOAD = I_CORE + I_IO = 10 mA + 10 mA = 20 mA
R_ON,DAUX2
On-resistance of switch
between AUX2 and VDSYS
I_LOAD = I_CORE + I_IO = 10 mA + 10 mA = 20 mA
R_ON,AVCC
R_ON,AAUX1
R_ON,AAUX2
On-resistance of switch
between AVCC and V_ASYS
On-resistance of switch
between AUX1 and V_ASYS
On-resistance of switch
between AUX2 and V_ASYS
I_LOAD = I_Modules = 10 mA
I_LOAD = I_Modules = 5 mA
I_LOAD = I_Modules = 5 mA
Auxiliary Supplies - Switching Time
over operating free-air temperature range (unless otherwise noted)
PARAMETER
TEST CONDITIONS
t_Switch
Time from occurrence of trigger (SVM or software)
to "new" supply connected to system supplies
t_Recover
"Recovery time" after a switch over took place.
During that time no further switching takes place.
Auxiliary Supplies - Switch Leakage
over operating free-air temperature range (unless otherwise noted)
PARAMETER
TEST CONDITIONS
I_SW,Lkg
Current into DVCC, AVCC, AUX1, or
AUX2 if not selected
Per supply (but not the highest
supply)
I_Vmax
Current drawn from highest supply
Auxiliary Supplies - Auxiliary Supplies to ADC10_A
over operating free-air temperature range (unless otherwise noted)
PARAMETER
TEST CONDITIONS
V₃
Supply voltage divider
V₃ = V_Supply/3
R_V3
Load resistance
t_Sample,V3
Sampling time required if V₃
selected.
