(LDO_1)
VDD_SYS_M
(VDD_LDO1) to VDD_SYS_M of DA9070.
J11
(LDO_2)
VDD_LDO2/
VDD_SYS_M
Install J11 jumper will connect LDO_2 input
(VDD_LDO2) to VDD_SYS_M of DA9070.
J12
(VO_BST)
BST_LD/ +/ S+/ S-/ -
+ and - are terminals for connecting external load to
the Boost output; When BST_LD (pin 1) is short to +
pin on J12, the on-board load resistor will be used as
the Boost output load. S+ and S- are kelvin sense
points for the Boost output. For output voltage
measurement during efficiency test, S+ and S- should
connect to multi-meter for better accuracy.
J13
VBAT_DIV/
GND_DIV/ I_MON/
TMP_SNS/ AGND
Sense points. For probe only.
J14
SW_BYPASS/
VDD_PWR/
SW_USE/ S+/ S-/
PGND
DA9070 power input (VDD_PWR) supply selection
and voltage sense. VDD_PWR can directly connect
to the 5V_USB rail by shorting J14 pin-1 to pin-2;
VDD_PWR can also connect to the 5V_USB rail
though load switch U1 by shorting J14 pin-2 to pin-3.
The load switch is controlled by the MCU during
battery profiling. For evaluation use jumper positions
1 and 2. J14-S+ and J14-S- pins are kelvin sense
points of DA9070 input VDD_PWR.
J16
(VDD_SYS_M)
S+/ S-
S+ and S- are kelvin sense points for DA9070
VDD_SYS.
J17
P_FLT, WD, S_FLT,
RIN_N, ITER_C,
AGND, ILIM_C,
AGND, ILIM_P,
AGND, ROUT_N,
MODE
Sense points. For probe only.
J18
(LDO0_LD)
LDO0_LD/ +/ -
+ and - are terminals for connecting an external load
to DA9070 LDO0 output; When pin-1 is shorted to the
+ pin on J18, the on-board load resistor will be used
as the LDO0 output load.
J19
(LDO1_LD)
LDO1_LD/ +/ -
+ and - are terminals for connecting external load to
DA9070 LDO1 output; When pin-1 is shorted to + pin
on J19, the on-board load resistor will be used as the
LDO1 output load.
J20
(LDO2_LD)
LDO2_LD/ +/ -
+ and - are terminals for connecting external load to
DA9070 LDO2 output; When pin-1 is shorted to + pin
on J20, the on-board load resistor will be used as the
LDO2 output load.
J21
(VO_BUCK_M)
+/ S+/ S-/ -
+ and - are terminals for connecting an external load
to DA9070 Buck output; S+ and S- are kelvin sense
points for DA9070 Buck output. For output voltage
measurement during efficiency test, S+ and S- should
connect to multi-meter for better accuracy.
