Overview
The TPS75R01A is an ideal diode controller that operates with an external N-channel MOSFET for reverse protection applications or redundant power supply applications. The forward voltage drop is controlled at as low as 20 mV, which can significantly reduce power loss to replace an ordinary Schottky Diode in power distribution networks.
The TPS75R01A supports a wide operating voltage range from 5 V to 75 V, with an absolute maximum rating of 100 V. The support for a transient 100-V input voltage is particularly suitable to meet the severe requirement in 48-V power supply systems.
The TPS75R01A integrates a charge pump to drive the external N-channel MOSFET. The device provides precise gate control to regulate the voltage drop between the source and drain at 20 mV. When it detects a reverse voltage of −10 mV from IN to OUT, the TPS75R01A turns off the external MOSFET within 25 ns typical to ensure no reverse current flows. The TPS75R01A also features a MOSFET test mode. It allows the MCU controller to test the shorted MOSFET.
The TPS75R01A provides a small SOT23-6 package, and it is qualified to operate within the junction temperature range from −40°C to +125°C.
