Linear Technology LTC1473
The LTC1473 drives two sets of backto-back N-channel MOSFET switches to route power to the input of the main system switching regulator. The LTC1473 senses current to limit surge currents both into and out of the batteries and the system supply capacitor during switch-over transitions or during fault conditions.| Part No. | LTC1473 |

FEATURES
s s DESCRIPTIO s s s s s Power Path Management for Systems with Multiple DC Sources All N-Channel Switching to Reduce Power Losses and System Cost Switches and Isolates Sources Up to 30V Adaptive High Voltage Step-Up Regulator for N-Channel Gate Drive Capacitor Inrush and Short-Circuit Current Limited User-Programmable Timer to Limit Switch Dissipation Small Footprint: 16-Pin Narrow SSOP The LTC®1473 provides a power management solution for single and dual battery notebook computers and other portable equipment. An internal boost regulator provides the voltage to fully enhance the logic level N-channel MOSFET switches. A user-programmable timer monitors the time the MOSFET switches are in current limit and latches them off when the programmed time is exceeded. A unique “2-diode mode” logic ensures system start-up regardless of which input receives power first. , LTC and LT are registered trademarks of Linear Technology Corporation.
