MPD8020
CMOS/DMOS Semicustom High-Voltage Array
Summary Information*—Not Recommended for New Designs
General Description
The Micrel MPD8020 is a
Integrated Circuit (ASIC). The MPD8020 features an array of
low-voltage CMOS analog and digital circuits and highvoltage DMOS power transistors on a monolithic integrated
circuit. The MPD8020 provides the customer a proprietary
design with size, reliability, performance advantages.
Quick Turnaround
Prepared wafers can be held prior to the final process
(metallization) where the customer’s unique interconnect
pattern is applied. This speeds turnaround by allowing many
of the fabrication steps to be completed before the final
design is finished.
Voltage Ratings
The MPD8020’s logic and analog circuitry operate from a
single +5V to +15V supply. The high-voltage section operates from +20V to +100V. An optional internal charge pump,
plus two external components, can drive the internal N-channel
DMOS FET gates approximately 15V higher than the highvoltage supply as required by high-side switch applications.
Fabrication Process
The MPD8020 CMOS/DMOS Semicustom High-Voltage Array
uses Micrel’s proprietary process which combines TTL/CMOS
compatible high-speed CMOS logic, CMOS analog, bipolar
analog, and high-voltage DMOS power devices in single IC.
