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
