MPD8020 CMOS/DMOS/Bipolar Semicustom Array

MPD8020

CMOS/DMOS Semicustom High-Voltage Array

Summary Information*—Not Recommended for New Designs

General Description

The Micrel MPD8020 is a

Smart Power Application Specific

Integrated Circuit (ASIC). The MPD8020 features an array of

low-voltage CMOS analog and digital circuits and high-

voltage 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 oper-

ates 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 high-

voltage 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.

Package Options

• Dice

• 16-pin to 48-pin plastic DIPs

• 16-pin to 48-pin ceramic DIPs

• Ceramic LCCs

• PLCCs

• Surface mount packages

• Fused-lead PLCCs and DIPs

• Custom packages

Support

The MPD8020 is supported from concept to packaged ICs by

Micrel’s designers, CAD systems, CAE simulations (includ-

ing SPICE, HILO, TIMVER), and an experienced fabrication

and test group.
