The primary high -performance silicon scheme supplier of high -energy -efficiency electronic products, on Semiconductor, launched the current mirror Cat2300 with switch controller. This device is used with Ansonami’s NTMFS4833NS or NTMFS SenseFET power MOSFET devices. Provide a compact Electric Filter Fan Cabinet Heater Fan Heater with Thermostat and high -efficiency current monitoring solution. The combination of these new devices provides system -level power management and is used for portable computers and network devices.
Several control and matching Sensefet’s Sense output and KELVIN voltage pins of Cat2300 to ensure accurate current monitoring within the complete work range of the SenseFet.
CAT2300 provides a single chip solution selection outside the separation circuit solution, which can provide precision current measurement of sensor -free sensor for 0.9 volt (V) to 5 V power input terminals. This new device provides a current mirror of up to 70 mAh (MA) -equivalent to 25 amp (A), which is equivalent to the measured current, and the logical level of integrated power MOSFET is controlled on/off control and its own circuit, which reduces the power consumption to almost almost almost almost Zero. This device also contains a soft startup function. The current consumption in the closing mode is less than 1 Weian (μA), and the use time is extended with the battery power application. The CAT2300 uses a low height of 2 mm x 3 mm TDFN-8 to save space, which is suitable for the full -40 OC to +85 OC working temperature range.
NTMFS4833NS and NTMFS4854NS are all 30 V and N -channel SenseFet MosFet, which offers lossless current measurement and higher accuracy. They also have low divert impedance, low -capacitance and low -door charge, minimizing the conductivity, drive and switching loss. The rated currents of NTMFS4833NS and NTMFS4854NS are 26 A and 24 A, respectively.
Paul Leonard, deputy president of Anson Mei Semiconductor MOSFET, said: "Based on our dual device combination to replace the separation scheme containing multiple meta devices, it can provide the area of ??printed circuit board (PCB), reduce power consumption and improve reliability, etc. Advantages. CAT2300 has been optimized to collaborate with our SenseFet device to provide simple, compact and high -energy precise current monitoring solutions for extensive fixed and portable equipment applications.
