Kinetic Technologies Unveils Load Switch with Adjustable Current Limit

Kinetic Technologies enhances its load switch portfolio with the new KTS1665. This newly launched device is a low-resistance load switch with an adjustable current limit, soft-start, and “ideal diode” reverse current protection. 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 VBUS. 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” reverse current protection (RCP) isolates the system’s internal rail whenever VBUS is driven to a higher voltage, as when charging. A FLT flag indicates an over-current or over-temperature fault condition. The KTS1665 is available in advanced, fully “green” compliant, 1.31 x 1.31 mm, 9-bump Wafer-Level Chip-Scale Package (WLCSP).
