|---|---|---|---|
| SULN2803A | SULN2803A is a monolithic, high-voltage, high-current Darlington array containing eight independent Darlington drivers. Integrated freewheeling diodes drive inductive loads such as relays and stepper motors. Each collector can provide 500mA; paralleling devices increases output current. Applications include relay, lighting, LED display, stepper-motor, and logic-buffer driving. … | 50V | QFN20(4*4) |
| SULN2001 | Three-channel Darlington driver circuit | ~ | SOP8 |
| SMXD2002 | SMXD2002 is a control-driver circuit for small-appliance control boards. It integrates four 100mA relay drivers with demagnetizing diodes and one 5V/100mA regulator. The relay drivers use Darlington outputs. | 40V | SOP14,DIP14 |
| SMXD2000 | SMXD2000 is a dual Darlington driver with an integrated 78L05 three-terminal regulator that provides a stable 5V output. Its Darlington drivers are optimized for switching inductive loads such as relays, and integrated freewheeling diodes absorb relay turn-off voltage spikes. Each channel outputs 200mA; paralleling devices increases output current. … | 40V | SOP8 |
| SMXD2001 | Three-way Darlington transistor array | 40V | SOP8 |
| SULN2803L | SULN2803L is a high-current Darlington array designed for low-voltage systems. It contains eight independent Darlington devices, each with a freewheeling diode for driving inductive loads such as relays and stepper motors. A single device provides 500mA output at input voltage as low as 1.8V; paralleling devices increases output current. Applications include relay, lighting, display, stepper-motor, and logic-buffer driving. … | 18V | SOP18,SSOP24，QFN20 |
| SULN2003 | Seven-channel Darlington transistor array | 50V | DIP16 SOP16 |
