3 Description
The LM74722-Q1 ideal diode controller drives and
controls external back-to-back N-Channel MOSFETs
to emulate an ideal diode rectifier with power path
ON and OFF control and overvoltage protection.
The wide input supply of 3 V to 65 V allows
protection and control of 12-V and 24-V automotive
battery powered ECUs. The device can withstand
and protect the loads from negative supply voltages
down to –65 V. An integrated ideal diode controller
(GATE) drives the first MOSFET to replace a Schottky
diode for reverse input protection and output voltage
holdup. A strong boost regulator with fast turn-ON
and OFF comparators ensures robust and efficient
MOSFET switching performance during automotive
testing, such as ISO16750 or LV124, where an ECU
is subjected to input short interruptions and AC
superimpose input signals up to 200-kHz frequency.
Low quiescent current 35 μA (maximum) in operation
enables always ON system designs. With a second
MOSFET in the power path, the device allows load
disconnect control using EN pin. Quiescent current
reduces to 3.3 μA (maximum) with EN low. The
device features an adjustable overvoltage cutoff or
overvoltage clamp protection using OV pin.
