Product Overview

The LTC4414IMS8#PBF is a near Ideal Diode for power switchover. 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. Two or more LTC4414s may be interconnected to allow switchover between multiple batteries or charging of multiple batteries from a single charger. The wide supply operating range supports operation from one to eight Li-Ion cells in series. 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. This pin may also be used to indicate to a microcontroller that an auxiliary supply is connected. The control (CTL) input enables the user to force the primary MOSFET off and the STAT pin low.
  • Designed specifically to drive large QG PFETs
  • Very low loss replacement for power supply OR'ing diodes
  • Minimal external components
  • Automatic switching between DC sources
  • 30µA Low quiescent current
  • Limited reverse battery protection
  • MOSFET gate protection clamp
  • Manual control input
  • Green product and no Sb/Br
