Other Parts Discussed in Thread: OPA548
我现在要用OPA548,它有个Current LImited功能,现在假设我设定输出电压5V,current limited设定为1A,然后接2Ω的负载,此时输出会有什么动作?直接shutdown还是让输出电压保持在2V,恒流输出1A??

THERMAL PROTECTION
Power dissipated in the OPA548 will cause the junction temperature to rise. The OPA548 has thermal shutdown circuitry that protects the amplifier from damage. The thermal protection circuitry disables the output when the junction temperature reaches approximately 160°C, allowing the device to cool. When the junction temperature cools to approximately 140°C, the output circuitry is again enabled
