- Detailed Description-Power Management Functions
8.2.2 Low voltage Current Sink (CURR1_GPIO1 … CURR4_GPIO4)
CURR1_GPIO1 … CURR4_GPIO4 can be controlled individually. Each one can sink up to 38.25mA. The voltage on
the current sinks must not exceed the supply VCURR_GPIO (can be connected e.g. to V SUPPLY ).
The low voltage current sinks and the gpio pins share the same pins (see General Purpose Input / Output
(CURR1_GPIO1 CURR4_GPIO4) on page 30) for enabling/disabling of the current sinks / gpio functions.
