ON Semiconductor introduces a family of high performance, VCEsat bipolar junction transistors (BJTs) that reduce overall circuit cost while contributing to better power efficiency and longer battery life in a variety of portable applications including cell phones, PDAs, media players, notebook computers and digital cameras. These low VCEsat BJTs are miniature surface mount devices featuring ultra-low saturation voltage (VCEsat) and high current gain capability. They are designed for use in low voltage, high-speed switching applications where affordable yet energy-efficient control is important. Suggested applications include power management, battery charging, low drop out regulation, vibrator motors, LED backlight, battery management, disk drive control and camera flash. By applying improved silicon technology and advanced packaging, the company developed this series of BJTs that deliver low saturation voltage performance equivalent to the RDSon performance of more expensive discrete solutions.
