carlos	9da569a830	Removing battery circuit ... Adding UMP1: 5V voltage regulator, allowing Input voltages up to 13V Adding USB - DC jack switching circuit: When USB cable is plugged in: USWAA PIN1 = 0V, USWBB PIN2 = 0V, VGate Q2 = 0, VGS Q2 = -USB_5V => Q2 ON VBAT= USB_5V When DC WALL ADAPTER is pugged in: USWAA PIN1 = 5V, USWBB PIN2 = 5V, VGate Q2 = 5V, VGS Q2 = 0V ???, => Q2 OFF, VBAT = UMP1 out. if plugg USB cable and DC wall adapter: USWAA PIN1 = 5V, USWBB PIN2 = 5V, VGate Q2 = 5V, VGS Q2 = 5V ???, => Q2 OFF, VBAT = UMP1 out. USB_5V & VBAT are isolated	2010-10-09 17:37:54 -05:00
