Fast Charging Batteries with Zetex High Current PNP Transistors & Benchmarq Controller
ICs - Zetec Semiconductors Applications Notes High current, fast
switching PNP transistors are capable of replacing large packaged P-Channel MOSFETs,
when attention is paid to the base drive requirements. This enables space and
performance efficient designs at much reduced cost. (app note added 2/06)

Finger Touch Activated Switch - It does not get any easier if you want a
solid-state switch that is activated by the touch of a finger. Two small metal pins
route voltage through the finger skin to a MOSFET switch. The circuit is great for
situations where a membrane type mechanical switch is not desired. …. [Designed by

Four-transistor H-bridge - an interesting 4-transistor H-bridge variant;
this is cheap and easy to build, and best of all is "smokeless" (i.e., no combination
of inputs can cause the bridge to self-destruct). (added 6/06) |

Gate-drive method extends supply's input range - 26-Jun-03 Issue of EDN
Industrial and telecom applications often require a nonisolated, low-voltage supply
from a high-voltage input. IC manufacturers have responded to that need with the
application of high-voltage processes and offer control ICs that work to 50V and
higher. That voltage is sometimes insufficient, and you need further design techniques
to extend the input voltage.... [Design Idea by John Betten and Robert Kollman, Texas
Instruments, Dallas, TX] |
