Apex擴大PWM放大器IC的設計(英文內容)
(產品新聞, 2006年2月15日)
|
Apex has extended the design performance for pulse width modulation (PWM) amplifier ICs with the development of a new 5A, 60V monolithic. The SA56 delivers increased power to drive a wider range of DC and stepper motors of up to 1/3-HP, while the use of PWM technology provides power delivery to minimize thermal issues. With this single chip device, system level designers can integrate sophisticated motion control into their designs without being experienced analog or power designers. The SA56's power delivery ranges from 250W to 500W. This represents an increase of nearly 50% compared with other available PWM ICs. Another customer advantage is the ability to select between analog or digital input. The SA56 is compatible with TTL and CMOS inputs for digital motor control. For analog systems, an onboard PWM oscillator and comparator make it possible for the IC to convert analog signals to PWM direction and magnitude. The SA56 is offered in a 23-pin staggered lead IC package. The heat tab on the package is tied to -VS. The SA56 is priced $8.90 in production volume quantities.
