FNB41560: Motion SPM® 45 Series

FNB41560 is a Motion SPM® 45 series that Fairchild has newly developed to provide a very compact and high performance inverter solution for AC motor drives in low-power applications such as washing machines and industrial fans. It combines low-loss short-circuit rated IGBTs and optimized gate drivers in a fully isolated package to deliver a simple and robust design. The system reliability is further enhanced by the built-in NTC for temperature monitoring, integrated under-voltage lock-out function for both high and low side, and an over-current protection input. Three separate open-emitter pins for low side IGBTs make three leg current sensing possible. Built-in bootstrap diodes and dedicated VS pins make PCB layout easy.

Features

• 600V, 15A 3-phase IGBT inverter including control ICs for gate drive and protections
• Easy PCB layout thanks to the built-in bootstrap diodes and the dedicated Vs pins
• Three separate open-emitter pins from low side IGBTs for three leg current sensing
• Single-grounded power supply with bootstrap operations
• Built-in thermistor for temperature monitoring
• Isolation rating of 2000Vrms/min.
