Figure 5. Output Stages
QH
The maximum sink current available at the outputs is a
function of the resistor connected between Pin 6 and ground
(see section on Bias/Set operation). Whenever the outputs
are to be in a high impedance state, both transistors (QH and
QL of Figure 5) of each output are off.
VD
This pin allows for provision of a current path for the motor
coil current during switching, in order to suppress back–EMF
voltage spikes. VD is normally connected to VM (Pin 16)
through a diode (zener or regular), a resistor, or directly. The
peaks instantaneous voltage at the outputs must not exceed
VM by more than 6.0 V. The voltage drop across the internal
clamping diodes must be included in this portion of the design
(see Figure 6). Note the parasitic diodes (Figure 5) across
each QL of each output provide for a complete circuit path for
the switched current.
