Pin Configuration and Functionality
IN- Inverting Driver Input
IN- inverted control signal for driver output if IN+ is set to high. (Output sourcing active at IN- = low and IN+ = high)
Due to internal filtering a minimum pulse width is defined to ensure robustness against noise at IN-. An internal
pull-up-resistor favors off-state.
GND1
Ground connection of input circuit.
VCC2
Positive power supply pin of output driving circuit. A proper blocking capacitor has to be placed close to this supply
pin.
OUT+ Driver Source Output
Driver output pin sourcing current to turn on external switch transistor. During on-state the driving output is
switched to VCC2. Switching of this output is controlled by IN+ and IN-, resp.. This output will also be turned off
at an UVLO event.
During turn off the OUT+ terminal is able to sink approx. 100 mA.
OUT- Driver Sink Output)
Driver output pin sinking current to turn off external switch transistor. During off-state the driving output is switched
to GND2. Switching of this output is controlled by IN+ and IN-, resp.. In case of UVLO an active shut down keeps
the output low.
GND2 Reference Ground
Reference ground of the output driving circuit.
In case of a bipolar supply (positive and negative voltage with respect to switch source potential) this pin is
connected to the negative supply voltage.
