CXES4276 CXES4276A CXES4276B集成了高边N沟道MOSFET和低边N沟道MOSFET以及自适应死区控制。CXES4276A CXES4276B具有内置的三态脉冲宽度调制输入功能，可支持多个脉冲宽度调制控制器。当PWM输入信号保持三态时，三态函数在不考虑ZC函数的情况下关闭高侧MOSFET，打开低侧MOSFET。该装置还配备了上电复位（POR）和使控制功能成为一个单一的包和准确的电流限制。该器件的过流保护通过使用低边MOSFET的RDS（ON）上的电压降来监测输出电流，从而消除了对高效率和低成本的电流传感电阻的需求。带滞后的POR电路监测VCC电源电压，以便在通电/断电时启动/关闭IC。CXES4276A CXES4276B也可以由其他电源系统启用或禁用。将EN引脚拉高或拉低将打开或关闭设备。
