Low-Power is Life Saver for Medical Electronics Devices

November 11, 2008 11:24 am | by Steve Kennelly, Microchip Technology Inc. | Articles | Comments

Designers of portable medical devices face unique challenges. Their chosen field is known for regulatory scrutiny, protracted design and life cycles, and a need for unparalleled robustness in the finished product. In addition, design objectives that are common to all electronics can have special significance when it comes to medical devices. For example, low power consumption is always an objective for designers of portable electronics. Less power means a smaller and lighter battery, which enhances portability.
