The LTC

廬

1473L provides reliable and efficient switching

between two DC power sources. This device drives two

external sets of back-to-back N-channel MOSFET switches

to route power to the input of a low voltage system. An

internal boost regulator provides the voltage to fully en-

hance the logic-level N-channel MOSFET switches while

an internal undervoltage lock-out circuit keeps the system

alive down to 2.8V.

The LTC1473L senses current to limit inrush between the

batteries and the system supply capacitor during switch-

over transitions or during fault conditions. A user-pro-

grammable timer monitors the time the MOSFET switches

are in current limit and latches them off when the pro-

grammed time is exceeded.

A unique 鈥?-diode鈥?logic mode ensures system start-up

regardless of which input receives power first.
