Current Sinks
These are general-purpose current sinks intended to control the backlight(s), buzzer and vibrator. The low voltage
current sink has an integrated protection against over voltage and can therefore also drive inductive loads (V PROTECT ).
DCDC_CURR1 and DCDC_CURR2, DCDC_CURR3 are high voltage (15V) current sinks, e.g. for series of white
LEDs
CURR1_GPIO, CURR2_GPIO, CURR3_GPIO, CURR4_GPIO are four 5V, 38.25mA current sinks, e.g. for buzzer,
vibrator, LEDs
CURR1_GPIO, CURR2_GPIO, CURR3_GPIO, CURR4_GPIO can be used as general propose Input/Output (GPIO)
functions optional (described in section General Purpose Input / Output (CURR1_GPIO1 … CURR4_GPIO4)).
