Linear Technology introduces the LTC4413, a two-channel ideal diode designed to reduce heat, voltage drop, and board space, as well as preserve battery life. The device is suitable for applications requiring an ideal diode or function for load sharing or automatic switchover between two input power sources. Equipped with several intelligent circuits, the LTC4413 has control access to each ideal diode — allowing for adjustment of the switchover voltage — and indicates whether the selected ideal diode is conducting. It also offers current limit and thermal protection as well as slow turn-off to protect against voltage spikes. A thermally enhanced 3 × 3 mm DFN package permits each channel to deliver up to 2.6 A from an input supply ranging from 2.5 to 5.5 V. The ideal diode has a low forward voltage of 80 mV at 500 mA and 210 mV at 2 A, and 1 uA of leakage current.
