    摘要: A semiconductor device having a voltage sensing element is disclosed which allows reduction of power consumption in comparison with a conventional device and enables to obtain a sufficient output voltage to secure sensing accuracy even when an input voltage is small. In the voltage sensing element of the semiconductor device, an n.sup.- layer is formed on a front surface of a p.sup.- substrate. A p type diffused region and an n type diffused region are formed at a main surface of n.sup.- layer, spaced apart by a prescribed distance. An electrode is formed on p type diffused region, and an electrode is formed on n type diffused region. An electrode is formed on a rear surface of p.sup.- substrate. P.sup.- substrate and n.sup.- layer constitute a diode in a reversely biased state. As a result, power consumption is reduced in comparison with a conventional voltage dividing resistor circuit.

    摘要: A capacitor (C) and a Zener diode (ZD2) are connected in parallel to a high-voltage side drive circuit (2). when a Zener voltage (VZD2) is set 5V, a voltage which is charged up in the capacitor (C) is determined by the Zener voltage (VZD2). Hence, it is only necessarv to set a voltage (VCC) in a loxv-voltage d.c. power source (4) at a value which is higher than (VZD2+VD+VCE), where VD is a forward-direction voltage to a diode (Di) and VCE is an ON-voltage to a low-voltage side switching device (Q1). Since a variation in a charging voltage which is supplied to a high-voltage side drive circuit is suppressed, it is possible to drive a switching device with 5V.
