MPD8021

e™ Semicustom High-Voltage Array

Summary Information

General Description

The MPD8021 is a semicustom, high-voltage, mixed-mode,

power ASIC (Application Specific Integrated Circuit) suitable

for quantities from 10 to 100,000’s of pieces. Clients can

begin designing proprietary ASICs using a low-cost SPICE

simulator and the free MPD8021 Design Kit—available for

downloading via the Internet.

Technology

The MPD8021 features bipolar/CMOS/DMOS high-voltage

technology and is fabricated using Micrel’s proprietary BCD5

process to combine high-speed, low-voltage digital and ana-

log circuits with high-voltage DMOS power drive circuits on a

single chip.

All logic and analog circuitry is powered from a single +3V to

+12V supply. The high-voltage portion functions at voltages

from +20V to over +100V and includes a charge pump.

Rapid Turnaround

Micrel delivers rapid turnaround by applying a unique metal

interconnect pattern, based on the client’s design, to a stock

MPD8021 wafer.

To facilitate a rapid and low-cost design

approach, Micrel offers MPD8021 development programs

that range from limited assistance to full turnkey.

When you are ready for production, count on Micrel’s proven

fab and test group to provide timely deliveries of high-quality,

fully-tested, proprietary ICs.

Low-Cost Development

There is no cost or obligation to begin developing your own

MPD8021-based custom IC. “Kit parts” which are actual

working designs, featuring access to many internal functions,

are available for breadboarding circuits.
