This pin needs to be connected externally to the 6 DGND negative supply rail or the power ground Negative supply rail or power ground. When using the Half bridge with positive supply only, connect this pin to power ground and DGND pin. 7, 8 -V /PGND S When using the Half bridge in dual supply mode, connect this pin to the negative supply. 9, 10 OUT PWM output 11, 12 +V Positive supply rail S 2 SA110 Rev D
