Title: Driving circuit for voltage driven element
Inventor: YOSHIDA AKIO
IPC: H03K17/567
Filed: 1990-04-20
Abstract: PURPOSE:To constitute the driving circuit of a monolithic IC by connecting both current pull-in switching elements charging an input capacitance and discharging the charged charge therein in series between power supplies, and supplying a current turning on both the drive switching elements alternatively to the elements. CONSTITUTION:When an input transistor(TR) Q1 is interrupted, a constant current from a constant current circuit IB flows to a base of a TR Q2, which is energized and other output TR Q3 is interrupted. Thus, a base current flows to a current supply TR Q4, which is turned on and a gate input capacitance of a MOS field effect TR F is momentarily charged from a DC power supply VCC. On the other hand, when the TR Q1 is energized, the operation is reverse to above, the charge stored in the gate input capacitance of the TR F is momentarily discharged and the TR F is interrupted. Thus, power loss at the output stage is decreased and heat dissipation is less attended therewith, then the IC is integrated into a miniature package.

Accordingly, even when the IC card is extracted during IC card writing/reading operation, the data on the card are not destroyed. Therefore, the need of a locking mechanism can be eliminated from this IC card reader/writer.
