Description
Setting
Connection
SW1
VPWR Path
1-2
Connect a 3.7 V to 5.5 V supply either through
banana jacks J2 (positive) and J3 (ground) or
through wall adaptor via J1 connector
VIN Path
2-3
(5)
Connect a 2.8 V
(4)
to 4.5 V supply via J4 (positive)
and J3 (ground)
SW2
PWRON to GND
Open
Connects PWRON to GND when pushed
J5
VDOTP Path
1-2
Connects VDDOTP to VCOREDIG (load from
default values)
2-3
Connects VDDOTP to GND (load from
fuses/Try-before-buy)
J6
VIN supply to VIN pin
Closed
Connects VIN supply to VIN pin
J7
SWBST output to ADC mux
Closed
Connects SWBST output to ADC mux
J8
PWRON to GND
Open
Connects PWRON to GND
J9
VIN supply to 3.3 V LDO regulators
Closed
Connects VIN supply to the 3.3V LDO regulator
J10
STANDBY pin to logic
1-2
Connects STANDBY pin to logic low (ON Mode)
2-3
Connects STANDBY pin to logic high (Standby
Mode)
J11
SD_VSEL pin to logic
1-2
Connects SD_VSEL pin to logic low (Selects
VCC_SD = 2.85 V to 3.30 V)
2-3
Connects SD_VSEL pin to logic high (Selects
VCC_SD = 1.8 V to 1.85 V)
J12
Pull-up voltage for logic input pins
1-2
Uses VSNVS as pull up voltage for logic input pins
2-3
Uses VDDIO as pull up voltage for logic input pins
J13
VDDIO voltage source
1-2
Uses on-board discrete LDO as VDDIO voltage
2-3
Uses SW2 output as VDDIO voltage
J14
Coin cell to LICELL pin
Closed
Connects coin cell to LICELL pin
J15
VIN supply to VLDO1IN pin
Closed
Connects VIN supply to VLDO1IN pin.
J16
VIN supply to analog mux
Closed
Connects VIN supply to the analog mux - part of
the ADC circuitry using the FRDM-KL25Z board
J17
VIN supply to VLDO32IN pin
Closed
Connects VIN supply to VLDO34IN pin
J18
SW2 output to VLDO2IN pin
Closed
Connects SW2 output to VLDO2IN pin
J24
(6)
E-load channel A
Closed
Enables E-load channel A. Use GUI to set the
current
J25
(6)
E-load channel B
Closed
Enables E-load channel B. Use GUI to set the
current
Notes:
4.
Minimum start-up voltage is 3.1 V
5.
The 5.0 V input is provided by default (VPWR path.) To switch to the VIN path, first remove the glue from the SW1 switch, set it to the 2-3 position,
then connect the 3.1 V to 4.5 V supply to J4 and J3.
CAUTION
Using the SW1 in the 2-3 position will short J2 to ground (VPWR path). When using the VPWR path (J2 and J3), make sure SW1 stays
in the 1-2 position to avoid a supply short.
