MPD8021
e™ Semicustom High-Voltage Array
Summary Information
General Description
Features
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.
• 12 N-channel, 100V, 200mA, 10Ω,
fully-floating DMOS power FETs
(can be paralleled for 100V, 2.4A, 0.83Ω single,
half-bridge, or bilateral switches)
• 40 high-voltage PMOS FETs
(for level shifting, high-voltage amplifiers)
• 12 high-voltage 200Ω, DMOS FETs
(for level shifting, voltage amplifiers)
• 20 high-voltage, grounded-source,
DMOS FETs
(for level shifting, current mirrors)
• >100 uncommitted CMOS gates
• 12 CMOS/TTL I/O buffers
• 13 low-voltage CMOS tile arrays
(for op amps, comparators, digital circuitry)
• 14 dual-collector PNPs and 12 NPNs
(for trimmed bandgaps, low-offset amplifiers or com-
parators, temperature sensor)
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.
• 3-bit trimming network
(for production trimmed bandgaps or offsets)
• High- and low-value resistors and capacitors
(>1MΩ total resistance, 45pF total capacitance)
• 12V and 6V zener diodes
(gate-to-source clamps, voltage references)
• 67 I/O pads
(36 include 2kV ESD protection)
• Guaranteed –55°C to +150°C operation
• Several package options
• Low-cost prototyping program
• Design support via Internet
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
workingdesigns, featuringaccesstomanyinternalfunctions,
are available for breadboarding circuits.
