KTS1665 USB VBUS 3.3 A Ideal Diode Load Switch

The KTS1665 from Kinetic Technologies is a low-resistance load switch with adjustable current limit protection (CLP), soft-start, and ideal diode reverse current protection (RCP). It is optimized to protect systems with USB Type-C^® ports that source up to 15 W at 5 V and must withstand up to 29 V on V_BUS. The KTS1665 uses an external resistor to set the current limit from 500 mA to 3.3 A. Soft-start limits inrush current and automatic ideal diode RCP isolates the system's internal rail whenever V_BUS is driven to a higher voltage, as when charging. A FLT flag indicates an overcurrent or overtemperature fault condition.

The KTS1665 is available in an advanced, fully green compliant, 1.31 mm x 1.31 mm, 9-bump wafer-level chip-scale package (WLCSP).
