GENERAL DEscriptION

The SGM2541 bidirectional load switch is designed for systems or chargers with highuick charging capability and wireless charging capability. The device supports up to 20V operating input voltage (28V withstand) at USBIN pins, and provides input voltage-clamped protection for input surge events up to 130V. The device can also provide 16V reverse voltage at the OUT pins.

The two OVP threshold voltages (17V/13V) can be programmed through VP pin. The over-voltage protection function can ensure the safe operation of surge events in any state.

The addition of a wireless Rx with an enable/disable pin allows the load switch to implement an e 2:1 power multiplexer (PMUX).

The bidirectional device can detect and support USB-OTG applications. It also includes under-voltage lockout, over-voltage lockout and over-temperature protection circuits designed to automatically isolate the power switch terminals when a fault condition occurs.

The SGM2541 is available in a Green WLCSP-2.43×1.75-20B package. It operates over an ambient temperature range of -40℃ to +85℃.
