Malvern, Penna.—Vishay's SiP4610A/B protected high-side load switch, working from a 2.2- to 5.5-volt input for battery switching, USB peripheral ports, notebook computers and various hot-swapping applications, can handle a continuous output current of up to 1 amp. Designers can set the device's current limit using a single (external) resistor.
The SiP4610A/B carries under-voltage lockout and thermal-shutdown protection. The over-temperature circuitry turns off the power switch when the chip's junction temperature reaches +165°C; it turns the switch back on once the temperature drops below +145°C. The SiP4610A/B has a quiescent current of 9 microamps; operating current is less than 1 microamp in shutdown mode.
The SiP4610A has an active-low enable input. The SiP4610B has an active-high enable input. Available in lead (Pb)-free 5-pin SC-70 and thin SOT-23 packages, the SiP4610A/B is rated for operation over -40 to +85°C (ambient). It provides circuit designers with a pin-for-pin replacement for Advanced Analogic Technologies' AAT4610A.
