Product Overview

The LTC4416EMS#PBF is a low loss dual PowerPath Controller to create two near ideal diode functions for power switchover circuits. 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 25mV. 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. The LTC4416 integrates two interconnected PowerPath controllers with soft switchover control. The "soft-off" switchover permits the users to transfer between two dissimilar voltages without excessive voltage undershoot (or VDROOP) in the output supply. The LTC4416 also contain a "fast-on" feature that dramatically increases gate drive current when the forward input voltage exceeds 25mV. The LTC4416 "fast off" feature is engaged when the sense voltage exceeds the input voltage by 25mV.
  • Designed specifically to drive large and small QG PFETs
  • Very low loss replacement for power supply OR'ing diodes
  • Reverse battery protection
  • Automatic switching between DC sources
  • Low quiescent current (35µA per channel)
  • Load current sharing
  • MOSFET gate protection clamp
  • Precision input control comparators for setting switchover threshold points
  • Open-drain feedback points for customer specified hysteresis control
  • Minimal external components
