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 of page 7
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
