All the outputs can be activated as
PWM
, with variable duty cycle and with some differences based on the
outputs:
- the L M H outputs have a fixed frequency of 100 Hz
HIGH SIDE OUT
This type of output is useful when load is connected to ground on one
side and to output on the other. Out sources current to load connecting it
to external power supply. When deactivated, out goes in high impedence
disconnecting load from power supply
.
LOW SIDE OUT
This type of output is useful when load is connected to external power on
one side and to output on the other. Out sinks current from load
connecting it to GND. When deactivated, out goes in high impedence
disconnectiong load from GND.
FULL BRIDGE CONFIGURATION
This configuration requires 2 half bridges to work.
Load is connected between the outputs. Selecting
which out is active high or low, we can reverse voltage
across load. Due to this functionality, if we connect a
motor between the outs, we can manage the rotation
in both directions. Another useful condition in this
configuration is the brake. Pulling LOW both output
pdm could brake motor in specific position. Naturally,
using PWM we can also manage the speed of the
motor.
