Product Description
Product Description
ColdQuanta’s atom chip driver consists of two bidirectional voltage-controlled current sources designed to drive two atom chip traces. Each channel is independently capable of driving up to +/-5 A. The two channels are floating, and each has its own set of controls, indicators, inputs, and outputs. Balanced, differential inputs isolate the chip driver from control electronics. To accommodate atom chip traces that overlap, the two outputs are isolated from each other and from ground. Additionally, each channel of the chip driver features ColdQuanta’s electronic fuse (eFuse) protects against destructive overdriving of the load. The circuit acts like a conventional fuse but is more convenient because its timing characteristics can be adjusted, and it can be easily reset with the simple push of a button.
