MAX16173
Description
The MAX16173 is an ideal diode controller that provides system protection against input transients and reversecurrent conditions. The wide operating voltage range of 3V to 50V, bined with 3μA of shutdown current, make the MAX16173 ideal for automotive applications.
The MAX16173 features an integrated boost converter that is capable of driving the gate of the external n-channel power MOSFET 11V above the source during high load operation. Fast pull up and pull down current sources allow rectification of 50k Hz to 250k Hz AC ponents riding on the main supply input. A fast-acting parator allows the MAX16173 to block reverse-current flow by shorting the gate to the source when the input is driven 10m V (typ) lower than the output. In light load applications, the MAX16173 regulates the voltage between the source and drain of the external n-channel MOSFET to 20m V(typ). For high load applications, the gate is driven high to enhance operation mode to minimize power dissipation and to...
