Kinetic Technologies KTS1897 5ARMS VBUS OVP Load Switch
Kinetic Technologies KTS1897 5ARMS VBUS Over-Voltage Protection (OVP) Load Switch is a USB VBUS safety management load switch for up to 140W current-sink input for 28V EPR systems. The input operating range is 3V to 33V, with VBUS withstanding up to 39VDC and VSYS up to 35VDC. Ultra-fast OVP is internally set to 33V but optionally adjusted via external resistors. Low on-resistance minimizes heat and voltage droop.
The KTS1897A/B has an automatic reverse-current protection (RCP) feature that acts as an “ideal diode” with fast recovery and isolates VBUS when charging or powering the system via another port. When enabled, the KTS1897C/D supports bidirectional mode. Additional safety management includes short-circuit protection (SCP) during soft start, over-current protection (OCP), and over-temperature protection (OTP).
The Kinetic Technologies KTS1897 is packaged in an advanced, fully Green compliant, 2.56mm x 2.00mm, 20-bump wafer-level chip-scale package (WLCSP).
