Micrel MIC2803
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.| Part No. | MIC2803 |
