AAT4712IRN-T1

Power Path w/ Input Current Limit up to 2.4A Supercap Charger w/ POK and RDY TDFN34-16

The AAT4712 is a programmed, current limited P-channel MOSFET power switch designed for high-side load-switching applications for SSD memory buffer saving solutions. With the programmed current limit, the AAT4712 ensures that the power ratings of the host are not exceeded and balances the system load and supercap charging current automatically to provide enough system load current in top-priority. The integrated discharge path control assures that the system load can still be supported in the short term when the input power has not fully charged the supercap. The current limit is programmed by an external resistor allowing ±10% accuracy at room temperature.
