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 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. 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 (including SPICE, HILO, TIMVER), and an experienced fabrication and test group.
