Kinetic Technologies KTS1800 Load Switch

Kinetic Technologies KTS1800 Load Switch is a USB VBUS safety management load switch for up to 312W ISINK or 240W ISOURCE in 48V EPR systems. The operating range is 3V to 55V with input/output withstand up to 59VDC. Ultra-fast over-voltage protection (OVP) is internally set to 55V but optionally adjusted via external resistors. Low on-resistance minimizes heat and voltage droop. Reverse-current protection (RCP) in both sink/source acts as a 20mV “ideal diode” with fast recovery. Additional safety management includes short-circuit protection (SCP) during and after soft-start, ultra-fast over-current protection (OCP), programmable current-limit protection (CLP), over-temperature protection (OTP), and an integrated transient voltage suppressor (TVS) for IEC industry standard ±30kV ESD and ±130V surge ratings. Safe POK LDO and VBUS active-discharge circuits are also integrated. The Kinetic Technologies KTS1800 is packaged in an advanced, fully “green” compliant, 4.81mm x 3.79mm, 63-bump Wafer-Level Chip-Scale Package (WLCSP).
