Jumper
Description and configuration
JPN_SET1
Sets the output current of OUT1:
•
RIN_SET1_1 (36.5 k
Ω
): sets the output current to 10 mA
•
RIN_SET1_2 (7.32 k
Ω
): sets the output current to 50 mA
JPPWMO
PWM output enable:
•
IN_SET1: enables PWM at OUT1
•
IN_SET2: enables PWM at OUT2
JPN_SET2
Sets the output current of OUT2:
•
RIN_SET2_1 (14.7 k
Ω
): sets the output current to 50 mA
•
RIN_SET2_2 (7.32 k
Ω
): sets the output current to 100 mA
JPEN2/DEN2
Activate the device and diagnosis for OUT2:
•
EN1/DEN1: use the resistor divider on EN1/DEN1 (REN1/DEN1_1) to activate OUT2
•
EN2/DEN2: use separate resistor divider EN1/DEN1 (REN1/DEN1_1) to activate
OUT2. During tail function (board supplied via VS_TAIL), place jumper on
EN1/DEN1 position
JPOUT
On board load connection
•
OUT1: connects OUT1 to on-board load
•
OUT2: connects OUT2 to on-board load
JPD
Diagnosis management
•
GND: when a fault is detected only the channel under fault condition will be
deactivated. The error will be communicated via ERRN
