CXES4275CXES4275A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。CXES4275 CXES4275A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。CXES4275 CXES4275A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。

产品概述 返回TOP
The CXES4275 CXES4275A CXES4276 integrates a high-side N-channel MOSFET and a low-side N-channel MOSFET with adaptive dead-time control. The CXES4275 CXES4275A CXES4276 have a built-in tri-state PWM input function which can support a number of PWM controllers. When the PWM input signal stays tristate, the tri-state function shuts off the high-side MOSFET and turns on the low-side MOSFET without consider ZC function. The device is also equipped with Power-OnReset(POR) and enable control functions into a single package and accurate current limit. The device over-current protection monitors the output current by using the voltage drop across the RDS(ON) of low-side MOSFET, eliminating the need for a current sensing resistor that features high efficiency and low cost. The POR circuit with hysteresis monitors VCC supply voltage to start up/shutdown the IC at power-on/off. The CXES4275 CXES4275A CXES4276 also can be enabled or disabled by other power system. Pulling the EN pin high or low will turn on or shut off the device.
