GENERAL DESCRIPTION

The SGM2539 is a 5A unidirectional USB power

delivery (PD) high-side switch with under-voltage

lockout (UVLO), over-voltage lockout (OVLO), reverse

current (RCP) and over-temperature (OTP) protections.

This switch can tolerate up to 29V at VBUS pin (22V at

VINT pin) when it is turned off. It can automatically turn

off and disconnect the terminals under fault conditions.

Two SGM2539 devices can be paralleled for

connecting two USB power inputs for charging the

device battery.

The SGM2539 has a default 22.75V over-voltage protection

threshold and it can be changed by an external resistor

divider connected to the OVLO pin. To limit the inrush

current, a 15ms debounce time followed by a soft-start

time is applied before turning the switch on.

The SGM2539 recommended operating voltage range

is from 2.5V to 20V. It is typically used for controlling

the power delivery from the sources connected to the

USB ports of system with necessary protection features.

For the USB PD applications such as cell phones,

tablets or notebooks, the SGM2539 provides a reliable

path to charge the internal battery from the power

delivered to the USB ports.

The SGM2539 is available in a Green WLCSP2.56×1.54-15B package and can operate over a

temperature range of -40℃ to +85℃.
