Kinetic Technologies KTS1690A USB VBUS ISOURCE Load Switch
Kinetic Technologies KTS1690A USB VBUS ISOURCE Load Switch is a low-resistance load switch with adjustable current limit, soft-start, fast turn ON mode, "ideal diode" reverse current protection, and an integrated Transient Voltage Suppressor (TVS). The KTS1690A is optimized to protect systems with USB Type-C™ ports that source up to 15W at 5V and must withstand up to 29V on VBUS (OUT pin). The KTS1690A uses an external resistor to set the current limit from 400mA to 3.7A.
The soft-start feature of the KTS1690A limits the inrush current, while the FON logic input enables fast turn ON mode for USB fast role swap (FRS). Automatic "ideal diode" reverse current protection (RCP) isolates the system's 5V internal rail whenever VBUS (OUT pin) is driven to a higher voltage, as when charging. The integrated TVS provides IEC Standards ±8kV ESD contact, ±15kV ESD air gap, and ±80V surge ratings for robust system protection. A ̅F̅L̅̅T̅̅\ flag indicates an over-current or over-temperature fault condition.
The Kinetic Technologies KTS1690A USB VBUS ISOURCE Load Switch is available in advanced, fully "green" compliant, 1.98mm x 1.98mm, 16-bump Wafer-Level Chip-Scale Package (WLCSP).
