ONFIGURATION
The PAC5220WP allows customers to configure certain behaviors on the PCB using resistor component
value selection, to customize their product behavior. Using the VCC33 3.3V supply, there are three sets
of resistor dividers that can be used for this customization.
To enable this feature, make sure to tie RCFGEN to ground or left floating. If this signal is tied to VCC33,
the default values from the tables below will be used.
The features that can be configured are LED behavior, dead-time and FOD threshold. Each feature that
can be configured has a resistor divider like shown below:
When the PAC5220WP is powered-up, the RFCGEN signal will be sampled. If it is low, then VLEDCFG,
DTCFG and FODCFG will be sampled. Based on voltage sensed on these signals, the configuration from
the tables below will be applied.
LED Configuration
The table shows the configuration options for LED behavior, based on the LEDCFG analog input.
