探索安森美针对电池供电工具的先进半导体解决方案。探索MOSFET、栅极驱动器、BLDC电机驱动器和电源管理技术,为无绳应用提供高效、可靠和紧凑的设计。

概览

电池供电工具(又称无绳工具)因其便携性、高效性和易用性,越来越多地被建筑、木工、汽车和DIY等行业所采用。这些工具通常使用12V至72V的可充电锂离子电池组,能量密度高,循环寿命长。

核心系统包括电池管理单元、电源树和电机驱动级,通常采用无刷直流(BLDC)电机,以提高效率和降低噪音。安森美为这些应用量身定制了全面的解决方案组合,包括低压和中压MOSFET、栅极驱动器、LDO稳压器和超级结MOSFET,通过将智能电源和传感技术集成到紧凑、坚固和热效率高的设计中,降低了系统成本,加快了产品上市时间。

产品

Low/Medium Voltage MOSFETs
Si MOSFETs control current flow between source and drain terminals via gate voltage. They're widely used in power amplifiers, voltage regulators, and switching circuits for their efficiency, speed, and power-handling capabilities.
Gate Drivers
GaN, IGBT, FET, MOSFET, H-Bridge MOSFET, and SiC MOSFET inverting and non-inverting drivers ideal for switching applications.
Silicon Carbide (SiC) Cascode JFETs
Our high-performance SiC cascode JFETs deliver best-in-class switching speed, lower switching losses, and higher efficiency. They provide high switching frequency and deliver ultra-low on-resistance (RDS (on)) starting at just 5mohm, utilizing less than half the die size of any other technology. Available in both standard thru-hole (including Kelvin) and surface mount packages, they offer excellent cost-effectiveness. These devices utilize a unique cascode configuration, integrating a high-performance SiC fast JFET with a cascode-optimized Si-MOSFET. This innovative approach enables standard gate drive (0-12V) for SiC devices. Given their smaller die size and compatibility with existing driver solutions, the SiC cascode JFETs offer optimized system performance and cost structure.
High Voltage MOSFETs
Portfolio of high voltage super-junction (SJ) MOSFETs meant for general usage and for several applications such as Power Factor correction, server/telecom power, led lighting.
Inductive Sensing
A selection of high performance devices for interfacing with inductive position sensors for industrial and automotive applications
Motor Drivers, Brushless
