WebAn IC process with a wide range of devices up to 1200 V is described. In addition to low-voltage bipolars and CMOS and 230-V VDMOS it provides 700-V high-side LDMOS, HV-PMOS (EPMOS) and low-voltage circuitry, low-side 1200-V LDMOS and 700-V LIGBT (lateral insulated-gate bipolar transistor), as well as 700-V interconnection. These features have … WebLDMOS channel current is controlled by the vertical electric field induced by the gate and the lateral field that exists between the source and drain. Figure 1: Basic DMOS Structure The …
WebA fast way to know is it is defective is measuring the ohmic resistance between: Source and Gate and between: Source and Drain. The resistive value must be high, very high (several MOhm or infinite) . On the other side, when the LDMOS is broken this value change really significantly e becomes of few KOm or even few Ohm.
WebMultiple Silicon Technologies on a Chip, 1985. SGS (now STMicroelectronics) pioneered the super-integrated silicon-gate process combining Bipolar, CMOS, and DMOS (BCD) transistors in single chips for complex, power-demanding applications. The first BCD super-integrated circuit, named L6202, was capable of controlling up to 60V-5A at 300 kHz. WebFeb 4, 2016 · 2/4/2016 By Dave Knight.
