In summary, Vishay’s Smart Load Switches, SiP32458 and SiP32459 are of a P-channel MOSFET switching element with integrated gate pump that provides 20 mΩ switch on resistance over a wide input voltage range. These devices have low voltage logic control threshold that can interface with low voltage control I/O directly without extra level shift or driver. A 2.8 MΩ pull-down resistor is integrated at logic control EN pin. The SiP32431 and SiP4282 have a slew rate controlled high side switch. The switch is of a low ON resistance P-Channel MOSFET that supports continuous current up to 1.2 A. They operate with an input voltage from 1.8 V to 5.5 V. They offer under voltage lock out that turns the switch off when an input under voltage condition exists. The SiP32419 and SiP32429 are load switches that integrate multiple control features that simplify the design and increase the reliability of the circuitry connected to the switch. Both devices are 56 mΩ switches designed to operate in the 6 V to 28 V range. An internally generated gate drive voltage ensures good RON linearity over the input voltage operating range. The SiP32101 bidirectional battery switch features reverse blocking capability to isolate the battery from the system. These internal switches feature ultra-low 6.5 mΩ (typ) on-resistance and operate from a +2.3 V to +5.5 V input voltage range. These smart switches are ideal for smart phones, GPS, portable media players, tablet computers, medical and healthcare equipment, industrial and instruments, and game console applications.
