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