ON Semiconductor rolls Current Mirror
ON Semiconductor has rolled out CAT2300 current mirror with switch controller, which when combined with the company's NTMFS4833NS or NTMFS4854NS SENSEFET Power MOSFET devices, provides a compact, efficient solution for current monitoring. This combination of new devices allows system level power management in applications such as portable computers and networking equipment. Exact control and matching of the SENSEFET's SENSE output with the KELVIN voltage leads by the CAT2300 ensures accurate current monitoring over the SENSEFET's entire operating range. The NTMFS4833NS and NTMFS4854NS are 30 V, N-Channel SENSEFET MOSFETs that provide lossless current sensing with improved accuracy. They also combine low on-resistance, low capacitance, and low gate charge to minimize conduction, driver, and switching losses. The NTMFS4833NS and NTMFS4854NS are rated at 26 A and 24 A respectively.
The CAT2300 is offered in a Pb-free, RoHS-compliant TDFN-8 package, and is priced at USD0.56 per unit in 3,000 unit quantities. The NTMFS4833NS and NTMFS4854NS are offered in a Pb-free, RoHS-compliant SO-8 Flat Lead package, and are priced between USD0.87 - USD1.60 per unit in 1,500 unit quantities.
