Longer battery life for power tools
16 August 2011
Renesas has developed 100 A high-current power MOSFETs for motor drive in consumer products.
The new power MOSFETs cover a range of voltages, with three new products, including the N0413N, having a voltage tolerance of 40 V and three others, including the N0601N, having a voltage tolerance of 60 V. The new power MOSFETs have loss levels amongst the lowest in the industry, making them ideal for extending battery life. For example, the N0413N with 40 V voltage tolerance has an on-resistance (Ron) of only 2.7 mΩ, and the N0601N with 60 V voltage tolerance has an on-resistance (Ron) of only 3.3 mΩ (VGSS = 10 V standard value in both cases).
In recent years, the market for cordless power tools has seen an increase – especially among high-end models – in the use of brushless motors and other power efficiency measures to increase battery life. The power supply circuit of a typical power tool contains six power MOSFET devices, and there is increasing demand for power MOSFETs with low-loss characteristics (low on-resistance).
The company’s lineup of consumer power MOSFETs previously extended to a current rating of 83 A. In response to the increase in demand for power semiconductor devices for use in cordless power tools, Renesas Electronics has developed six new low-loss power MOSFETs designed to accommodate large currents of up to 100 A.
The new products are available with a voltage tolerance of 40 V or 60 V and in three package types, the TO-220AB and TO-262 and the surface-mount TO-263, for a total of six versions.
