摘要
高精度大电流控制器有着广泛的应用,但在高共模电压情况下输出电流的检测电路比较复杂。AD8205型高端电流传感器可以简化检测电路,采用AD8205和UC3842电流型PWM控制电路实现PWM可调电流源,电路结构简单可靠,输出电流精度高。
The high precision and large current controller are used widely.But in the situation where there is high common-mode voltage, the detection circuit of the output current is very complex. The new high-side current sensor AD8205 can simplify the detection circuit.The adjustable current source using AD8205 and current PWM controller UC3842 features such advantages as simplified reliable circuits and high precision output current.
