TRI_cap
Description
Ground connection (1). They also conduct heat from die to
printed circuit copper.
These TTL compatible logic inputs set the direction of
current flow through the load. A high level causes current to
flow from OUTPUT A to OUTPUT B.
Logic input of the internal DAC (1). The output voltage of the
DAC is a percentage of the Vref voltage applied according to
the thruth Table 5 on page 12.
See pin 3
Bridge output connection (1)
Disables the bridges for additional safety during switching.
When not connected the bridges are enabled
Triangular wave generation circuit capacitor. The value of
this capacitor defines the output switching frequency
