Torex Semiconductor, Ltd. Power Distribution Switches, Load Drivers XC8109BD10ER-G

The XC8109BD10ER-G is a P-channel MOSFET power switch IC designed for efficient power distribution with a low ON resistance of 85mOc at 5.0V. It supports an input voltage range of 2.5V to 5.5V and can handle a maximum output current of 0.9A. The device incorporates several protective features, including current limiting, reverse current prevention, thermal shutdown, and under-voltage lockout (UVLO). A flag output indicates the status of the power switch, providing a low-level signal during over-current or overheating conditions. The XC8109BD10ER-G is suitable for applications such as set-top boxes, digital TVs, PCs, USB ports, and HDMI devices. It operates within a temperature range of -40¬8C to 105¬8C and is packaged in a USP-6C format, compliant with EU RoHS standards. The current limit can be adjusted using an external resistor, and the CE pin allows for selectable logic levels for activation. The device also features a soft-start function and a typical current limit response time of 2Oºs.
