LTC4372 & LTC4373 Low IQ Ideal Diode Controllers

Analog Devices Inc. LTC4372 and LTC4373 Low I_Q Ideal Diode Controllers are designed to drive an external N-channel MOSFET to replace a Schottky diode. Compared to Schottky diodes, these devices control the forward voltage drop across a MOSFET to ensure lower loss current delivery from one path to the other, even at light loads. The LTC4372 and LTC4373 feature a low 5µA operating current and a low 0.5µA shutdown current. This increases efficiency in applications where the ideal diode is used for intermittent loads or always on standby channels, making the LTC4372 and LTC4373 suitable for battery-powered applications in portable instrumentation, automotive, and renewable energy fields. Additionally, the LTC4372 and LTC4373 can control back-to-back N-channel MOSFETs for inrush current control and load switching.
