LT8672

Active Rectifier Controller

with Reverse Protection

FEATURES

DESCRIPTION

The LT^®8672 is an active rectifier controller for reverse

input protection. It drives an external N-channel MOSFET

to replace a power Schottky diode. Its very low quiescent

currentandfasttransientresponsemeetthetoughrequire-

ments in automotive applications where AC input signals

of up to 100kHz are present. These signals are rectified

with minimum power dissipation on the external FET,

simplifying thermal management on the PCB.

AEC-Q100 Qualified for Automotive Applications

Reverse Input Protection to –40V

Improved Performance Compared to a

Schottky Diode

Reduce Power Dissipation by >90%

Reduce Drop to 20mV

Ultrafast Transient Response

Rectifies 6V Up to 50kHz

Rectifies 2V Up to 100kHz

P-P

With a drop of only 20mV, the LT8672 solution eases the

minimum input voltage requirement during cold crank

and start-stop, allowing simpler and more efficient cir-

cuits. If the input power source fails or is shorted, a fast

turn-offminimizesreversecurrenttransients.Anavailable

shutdown mode reduces the quiescent current to 3.5μA.

Wide Operating Voltage Range: 3V to 42V

Low 20µA Quiescent Current in Operation

Low 3.5µA Shutdown Current

Accurate 1.21V Enable Pin Threshold

Small 10-Lead MSOP Package, 10-Lead 3mm ×

2mm DFN Package and 3mm × 2mm Side-Wettable

DFN Package

An integrated auxiliary boost regulator provides the re-

quired boost voltage to turn the external FET fully on. A

power good pin signals when the external FET is ready to

take load current.
