DESCRIPTIO
The LTC ? 4416/LTC4416-1 control two sets of external
P-channel MOSFETs 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 aux-
iliary source is connected.
The LTC4416 integrates two interconnected PowerPath TM
controllers with soft switchover control. The “soft-off”
switchover permits the users to transfer between two dis-
similar voltages without excessive voltage undershoot (or
V DROOP ) in the output supply. The LTC4416/LTC4416-1 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. The LTC4416-1
enables the fast off under the same conditions and when
the other external P-channel device is selected using the
enable pins.
The wide operating supply range supports operation from one
to eight Li-Ion cells in series. The low quiescent current (35μA
per channel) is independent of the load current. The gate driver
includes an internal voltage clamp for MOSFET protection.
The LTC4416/LTC4416-1 are available in low profile 10-lead
MSOP packages.
