cnZHCS145–MARCH2011双通道功率驱动器查询样品:UC1707-SP1特性抗辐射:50kRad(Si)(对于5962-8761903VEA、5962-8761903VFA)(1)经QML-V标准认证,SMD(5962-8761901VEA,5962-8761903VEA,5962-8761903VFA,5962-8761901V2A)两个独立的驱动器1.
5A图腾柱输出反相及同相输入40ns上升及下降时间(采用1000pF电容时)可兼容高速、功率MOSFET低交叉传导电流尖峰具有可选锁存器的模拟停机功能电路低静态电流5V至40V工作电压具有热关断保护功能16引脚双列直插式封装(1)辐射容限是基于初始器件鉴定(放射量率=10mrad/sec)的典型值.
可提供辐射批量接受测试——详情请与TI联系.
说明UC1707功率驱动器采用高速肖特基工艺制造,可实现低电平控制功能部件与高功率开关器件(特别是功率MOSFET)之间的连接.
UC1707包含两个独立的通道,每个通道可由一个高或低输入逻辑电平信号来启动.
只要不超过功耗限值,每个输出能供应或吸收高达1.
5A的电流.
尽管每个输出都能利用其自己的输入来单独启动,但它可通过停机端子上的一个数字高电平信号或一个差分低电平模拟信号的作用共同强制为低电平.
来自任一电源的停机命令可以是闭锁,也可以不是,这取决于闭锁停用引脚的状态.
VIN和VC的电源电压可在5V至40V的范围内单独调节.
