NOTES:
PIN
7. Unless otherwise specified all pin names are active high. Those that are active low have an “n” prefix, such as nERRORA.
8. Thermal pad is internally connected to all 4 HGND ground pins (HGNDA, HGNDB, HGNDC, HGNDD). Any connection to the

Output stage A high voltage supply ground. A separate ground pin connection is provided
for each of the output stages. All of the HGND[A:D] pins connect to system “HV” power
ground (also see Note 8).
