Figure 8-48 shows an LTC1155 connected as a high-side MOSFET switch driver (Chapter 2). The circuit generate 12-V from a 5-V supply to fully enhance (switch) logic-level N-channel MOSFET switches, with no external components required. The supply current is typically 85 μA with the switch fully enhanced, and 8 μA with the LTC1155 in standby (both inputs off). This combination of a low-drop N-channel MOSFET switch and micropower driver is an efficient means of controlling power in complex loads. Switch efficiencies in the 99% range are practical.
