Filed: 1988-11-29
Abstract: PURPOSE:To reduce the number of components by utilizing a PN junction between base and emitter of 2 transistors (TRs) being a component of a voltage current conversion circuit as reverse voltage protection mutually. CONSTITUTION:A 1st voltage current conversion circuit being a circuit detecting the polarity consists of a TR 5, a resistor 3 and a polarity detection terminal 7 and a 2nd voltage current conversion circuit consists of a TR 6, a resistor 4 and a polarity detection terminal 8.
