Product Overview

The LTC4414EMS8#PBF is a low loss PowerPath Controller for large PFETs. This permits highly efficient OR'ing of multiple power sources for extended battery life and low self-heating. When conducting, the voltage drop across the MOSFET is typically 20mV. For applications with a wall adapter or other auxiliary power source, the load is automatically disconnected from the battery when the auxiliary source is connected. Two or more LTC4414s may be interconnected to allow load sharing between multiple batteries or charging of multiple batteries from a single charger. The wide supply operating range supports operation from one to six Li-ion cells in series. The low quiescent current (30µA typical) is independent of the load current. The gate driver includes an internal voltage clamp for MOSFET protection. The STAT pin can be used to enable an auxiliary P-channel MOSFET power switch when an auxiliary supply is detected.
  • Designed specifically to drive large QG PFETs
  • Very low loss replacement for power supply OR'ing diodes
  • 3.5 to 36V AC/DC Adapter voltage range
  • Minimal external components
  • Automatic switching between DC sources
  • Low quiescent current (30µA)
  • 3 to 36V Battery voltage range
  • Limited reverse battery protection
  • MOSFET gate protection clamp
  • Manual control input
