LTC4357
4357fd
pin Functions
Exposed Pad: Exposed pad may be left open or connected
to GND.
GATE: Gate Drive Output. The GATE pin pulls high, enhanc-
ing the N-channel MOSFET when the load current creates
more than 25mV of voltage drop across the MOSFET.
When the load current is small, the gate is actively driven
to maintain 25mV across the MOSFET. If reverse current
develops more than –25mV of voltage drop across the
MOSFET, a fast pull-down circuit quickly connects the
GATE pin to the IN pin, turning off the MOSFET.
GND: Device Ground.
IN: Input Voltage and GATE Fast Pull-Down Return. IN is
the anode of the ideal diode and connects to the source
of the N-channel MOSFET. The voltage sensed at this pin
is used to control the source-drain voltage across the
MOSFET. The GATE fast pull-down current is returned
through the IN pin. Connect this pin as close as possible
to the MOSFET source.
NC: No Connection. Not internally connected.
OUT: Drain Voltage Sense. OUT is the cathode of the ideal
diode and the common output when multiple LTC4357s
are configured as an ideal diode-OR. It connects to the
drain of the N-channel MOSFET. The voltage sensed at
this pin is used to control the source-drain voltage across
the MOSFET.
VDD: Positive Supply Input. The LTC4357 is powered from
the VDD pin. Connect this pin to OUT either directly or
through an RC hold-up circuit.
