The AAT4710 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 AAT4710 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. The AAT4710 integrates discharge path for SYS (to system load) from VCC input or OUT input (connect to supercap). The low R DS(ON) from OUT to SYS prolongs the supercap backup time when VCC drops below a threshold voltage which is programmed by an external resistor from ADJ to ground. The AAT4710 incorporates a POK function which can indicate system input power good. An ADJ pin is provided with the addition of an external resistor for setting the input power good detect threshold. The AAT4710 also incorporates a supercap charge ready (RDY) indicate function. The quiescent supply current is typically a low 70μA from the discharge path of VCC to SYS. The AAT4710 is available in a 16-pin TDFN34 package and is specified over a -40 to 85°C temperature range.
