To be connected with power grounds and to the ground layer
through vias to dissipate the heat.
Analog circuits ground.
Needed for internal pre-regulator filtering. The BYP pin is
intended only to connect an external ceramic capacitor. Any
connection of this pin to external current or voltage sources
may cause permanent damage to the device.
Two I²C bus addresses available by setting the Address pin
level voltage. See address pin characteristics table.
The resistor “RSEL” connected between ISEL and GND defines
the linear regulator current limit threshold by the equation:
I
To be left floating. Do not connect to GND.
Not internally connected pins. These pins can be connected to
GND to improve thermal performances.
MAX
(typ.) = 10000 / RSEL.
