The circuit is similar to Ericsson´s PBL 3771/1 and PBL 3772/1.
Key Features
- Dual chopper driver in a single package.
- Operation at -40 °C.
- 1000 mA continuous output current per channel.
- Low power dissipation, 2.6 W at 2 x 750 mA output current.
- Close matching between channels for high microstepping accuracy.
- Specially matched to the Dual DAC PBM 3960.
- Plastic 22-pin batwing DIP package or 28-pin power PLCC package with lead-frame for heatsinking through PC board copper. Phase 1 PBL 3774/1 Dis1 VR1 C.
