Overview
MIC2803/2804 Micrel 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 Ordering Information Part Number MIC2803BN MIC2803BWM MIC2804BN MIC2804BWM Temperature Range –40°C to +85°C –40°C to +85°C –40°C to +85°C –40°C to +85°C Package 18-pin DIP 18-pin wide SOIC 18-pin DIP 18-pin wide SOIC Functional Diagrams COM 2.
