供应M51996A波形发生器ic
信息内容：M51996的大概功能1脚：PWM输出晶体管的集电极2脚：PWM输出端，也是内部下拉晶体管的集电极3脚：内部下拉晶体管（保护用与2脚输出反相）的发射极，接与1脚同电源的负极4/13脚：好象是过热保护端，本图接负应是不用此功能5脚：过压保护，大于0.75V时停止PWM输出，本图接负取消此功能6脚：电压反馈端，实际反馈电流在0.6-1.4ma，占空比0-50%7脚：大于2.5V时可降低PWM输出频率，接负取消此功能8脚：内部辅助电源输出，精确的7.8V9脚：软启动端，电压变低时PWM频率可下降，此端接正表明取消该功能10/11/12脚：RC振荡外接回路，三者决定PWM输出的频率，本图约200KHZ14脚：IC电源的负端15脚：过电流检测，大于0.2V时停振，根据串接的取样电阻可算出限制电流16脚：IC的正电源，一般12-30V，本电路16V
