6.3 VDD Pin Supply Selection

The controller can be enabled and disabled by J7.

Default setting: VDD pin connected to VIN pins through R19

Table 6-3 The Controller Can Be Enabled and Disabled by J7(1)
SET ON CONNECTIONENABLE SELECTION
R19 = 0 ΩVDD pin connected to VIN pins
R19 = OpenVDD pin disconnected to VIN pins
(1) J7 requires the proper input voltage for power up. The VDD pin input voltage range is from 4.5 V to 25 V.
