+ * BST EN enable the boost regulator and Op-Amp
+ * DAC sets the current, max current depends on Vset voltage divider and Rsense
+ * HDR FET switches between high value Rsense (low current range, pin low),
+ *         and low value Rsense (high current range, pin high)
+ * IN- NFET : pull up after BST enable to eliminate startup flash, pull down otherwise
