3.2.2 Digital Outputs
The BL2100 has 16 digital outputs, OUT00–OUT15, which can each sink or source up to
200 mA. Figure 11 shows a wiring diagram for using the digital outputs in a sinking or a
souring configuration.
All the digital outputs sink and source actively. They can be used as high-side drivers,
low-side drivers, or as an H-bridge driver. When the BL2100 is first powered up or reset,
all the outputs are disabled, that is, at a high-impedance status, until the digoutConfig
software function call is made. The digoutConfig call sets the initial state of each digi-
tal output according to the configuration specified by the user, and enables the digital out-
puts to their initial status.
Figure 11. BL2100 Digital Outputs
OUT00–OUT07 are powered by to +K1, and OUT08–OUT15 are powered by +K2.
K1 and K2 can each be up to 36 V. They don't have to be same.
All the sinking current, which could be up to 3.2 A, is returned through the GND pins. Be
sure to use a suitably sized GND and keep the distance to the power supply as short as
possible. Since there are two GND terminals (header J5/J4, and header J11/J10), it is
