1A 20V low leakage Schottky rectifier (CASE 457-
04) ON SEMI MBRM120ET3
regulator controllers (V ON , V OFF , and V LOGIC ) with multiple
protection functions. A block diagram is shown in Figure 18.
Table 1 lists the recommended components.
The EL7585A integrates an N-channel MOSFET boost

converter to minimize external component count and cost.
The A VDD , V ON , V OFF , and V LOGIC output voltages are
independently set using external resistors. V ON , V OFF
voltages require external charge pumps which are post
regulated using the integrated LDO controllers.
