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. 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.
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 is available in a Green WLCSP-2.56×1.54-15B package and can operate over a temperature range of -40℃ to +85℃.
