Design a Custom BoardAbout This Component
Automotive-qualified ideal diode controller for 3V to 65V battery-powered systems, driving external back-to-back N-channel MOSFETs with 10.5mV forward voltage regulation. Integrates reverse input protection to –65V, adjustable overcurrent/overvoltage/undervoltage protection, and 2% accurate current monitoring. Suitable for automotive power distribution, active ORing, and load protection in ADAS and infotainment modules.
Package: QFN-24 (4×4mm) · 24 pins
Why does this need a breakout?
This 0.5mm pitch QFN is nearly impossible to hand solder and entirely incompatible with breadboards due to hidden pads beneath the package. A breakout board provides accessible headers and pre-soldered connections, letting you prototype with InvenSense motion sensors via I2C or SPI without specialized SMD equipment or rework skills.
