MIC2803/2804
High-Voltage High-Current Darlington Array
Not Recommended for New Designs
General
Features
The MIC2803 and MIC2804 are high-voltage, high-current
Darlington arrays ideal for switching high-power loads from
logic-level TTL, CMOS, or PMOS control signals.
• Output voltage to 50V
• Output current to 500mA
• Open-collector outputs
• Integral clamp diodes
• TTL, CMOS, or PMOS compatible inputs
The MIC2803/4 Darlington transistor array can be used to
manage multiple loads of up to 50V and 500mA, limited by
package power dissipation.
Applications
• Relay and solenoid switching
• Stepping motor
The MIC2803 features inputs compatible with 5V TTL and
CMOS logic while the MIC2804 features inputs compatible
with 6V to 15V CMOS or PMOS logic outputs.
• LED and incandescent displays
The MIC2803/4 is available in 18-pin plastic DIP and wide
SOIC packages in the –40°C to +85°C temperature range.
