The PBL 3771/1 is a switch-mode, constant-current driver IC (chopper) with two channels, one for each winding of a two-phase stepper motor. The circuit is especially developed for use in microstepping applications in conjunction with the matching dual DAC (Digital-to-Analog Converter) PBM 3960. A complete driver system consists of these two ICs, a few passiv.
• Dual chopper driver in a single package.
• 650 mA output current per channel.
• Close matching between channels for high microstepping accuracy.
• Selectable slow/fast current decay for improved high-speed microstepping.
• Improved low-level linearity.
• Specially matched to Dual DAC PBM 3960.
• Selection of packages, 22-pin “batwing” DIP, 24 pin "batwing" SOIC or 28-lead PLCC with lead-frame for heat-sinking through PC board copper.
