PNEV5190B evaluation board quick start guide
Figure 7. Figure title here
As soon as the board is supplied with power, the red LED D5 must be on.
The PNEV5190B has different supply pins for the PNEV5190M (module board) as shown
in
. For further details on the supply options of the PN5190 itself, refer to
.
Attention: there are PN5190 (IC) pins with the same name!

Table 1. PNEV5190M module supply pins
The PN5190B base board provides four LDOs:
1. U8 for supplying the PNEV5190M with VBAT. The default configuration provides
VBAT = 3.3 V. Optionally this voltage can be set to 4.8 V.
2. U5 for supplying the VDDIO and the µC supply (VDDIO_BRD = MCU_VDD =
MCU_VDDA) with 3.3 V. This LDO is not used in default configuration.
3. U6 for supplying the VDDIO and the µC supply (VDDIO_BRD = MCU_VDD =
MCU_VDDA) with 1.8 V. This LDO is used in default configuration.
4. U7 for supplying the overall board with 6 V. This LDO is used in default configuration.
The default configuration uses the following jumpers closed:
J9: 2-3 -> external power supply
J8: closed -> VBATPWR supplied with VBAT = 3.3 V
J12: closed -> VBAT supplied with 3.3 V
The default configuration uses the following jumpers open:
J3: open
