Микросхемы и комплектующие LTM9100IY#PBF

Контроллер горячей замены , высоковольтный, горячая замена, 4.5В - 5.5В питание, BGA-42

The LTM9100IY#PBF from Linear Technology is an Anyside high voltage isolated switch controller with I2C command and telemetry in 42 pin BGA package. This micromodule controller is a complete galvanically isolated switch controller with I2C interface for use as a load switch or hot swap controller. The load is soft started and controlled by an external N-channel MOSFET switch. Overcurrent protection minimizes MOSFET stress during start-up, input step and output short-circuit conditions. Owing to isolated, floating character of switch, it is easily configured for use in high side, low side and floating applications. The LTM9100 is ideal for use in networks where grounds can take on different voltages. Isolation in the LTM9100 blocks high voltage differences and eliminates ground loops and is extremely tolerant of common mode transients between ground planes. It is used in high voltage DC hot swap, live backplane insertion, isolated distributed power systems and breaking ground loops.
