3.2.2 Digital Outputs
The BL4S100 has eight digital outputs, OUT0–OUT7, which can each sink up to 200 mA.
Figure 8 shows a wiring diagram for using the sinking digital outputs.
OUT0–OUT3 are powered by +K1, and OUT4–OUT7 are powered by +K2. +K1 and
+K2 can each be up to 36 V. They don't have to be the same. All the sinking current, which
could be up to 1.6 A, is returned through the GND pin. Be sure to use a suitably sized
ground wire and keep the distance to the power supply as short as possible.
All the digital outputs sink actively. They can be used as low-side drivers, or as an H-bridge
driver. When the BL4S100 is first powered up or reset, all the outputs are disabled, that is,
at a high-impedance state.
Individual digital output channels may be used for PWM/PPM outputs.The use of these
channels for PWM/PPM is described in Section 3.2.2.1.
