Fairchild公司的FNA41560 是運動智能的功率模塊，包括有600V-15A 3相IGBT逆變器橋，控制IC和保護電路，逆變器的每相電流可單獨監(jiān)視，內(nèi)置的溫度調(diào)節(jié)器用來超溫監(jiān)視，絕緣指標2000Vrms/min，主要用在AC 100V ~ 253V三相逆變器驅(qū)動以及家用電器如空調(diào)和電冰箱。

FNA41560主要特性：

? 600V-15A 3-phase IGBT inverter bridge including control ICs for gate driving and protection

? Easy PCB layout due to built-in bootstrap diode and VS output

? Divided negative dc-link terminals for inverter current sensing applications

? Single-grounded power supply due to built-in HVIC

? Built-in thermistor for over-temperature monitoring

? Isolation rating of 2000Vrms/min.

FNA41560應用：

? AC 100V ~ 253V three-phase inverter drive for small power ac motor drives

? Home appliances applications like air conditioner and refrigerator
