LTC4415IMSE#PBF

LTC®4415 is a dual 4A ideal diodes with adjustable current limit contains two monolithic PowerPath ideal diodes, each capable of supplying up to 4A with typical forward conduction resistance of 50mohm. The diode voltage drops are regulated to 15mV during forward conduction at low currents, extending the power supply operating range and ensuring no oscillations during supply switchover. Less than 1µA of reverse current flows from OUT to IN making this device well suited for power supply ORing applications. Furthermore, the ideal diode currents can be monitored via CLIM pin voltages. When the die temperature approaches thermal shutdown, or if the output load exceeds the current limit threshold, the corresponding warning pins are pulled low. Typical applications are high current PowerPath™ switch, battery and wall adapter diode ORing, backup battery diode ORing, logic controlled high current power switch, supercapacitor ORing, multiple battery sharing.

• Two ideal diodes are independently enabled and prioritized using inputs EN1 and active-low EN2
• Output current limits can be adjusted independently from 0.5A to 4A using resistors on the CLIM pins
• Open-drain status pins indicate when the ideal diodes are forward conducting
• Low reverse leakage current (1µA maximum)
• 15mV forward drop in regulation
• Smooth switchover in diode Oring, load current monitor
• Precision enable thresholds to set switchover, soft-start to limit inrush current on start-up
• Status pins to indicate forward diode conduction, current and thermal limit with warning
• 16-lead plastic MSOP package
• Temperature rating range from –40°C to 125°C
