Name
Ground connection (1). They also conduct heat from die to
PWR_GND
printed circuit copper.
These TTL compatible logic inputs set the direction of
PH_1, PH_2
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
I
DAC is a percentage of the Vref voltage applied according to
1_1
the thruth

OUT1A
Bridge output connection (1)
Disables the bridges for additional safety during switching.
DISABLE
When not connected the bridges are enabled
Triangular wave generation circuit capacitor. The value of
TRI_cap
this capacitor defines the output switching frequency
