Abstract

A cost-effective, mixed technology process has been developed that extends the operating range of bipolar integrated circuits into the power integrated circuit regime. The process simultaneously produces CMOS (complementary metal-oxide-semiconductor) logic with a PNP vertical power device. The combination can withstand transients in excess of 85 V and jump start (24 V) and reverse polarity conditions while controlling several amperes of current, making it ideal for automotive applications. Two production devices and a new product that have been developed using the BiMOS (bipolar MOS) process are described: (1) a high-side switch that is used for controlling inductive loads; (2) a transient suppressor used to protect voltage-sensitive electronic components; and (3) a low-side, protected driver.
