PBL3775-1规格书详情
Description
The PBL 3775/1 is a switch-mode (chopper), constant-current driver IC with two channels, one for each winding of a two-phase stepper motor. The circuit is similar to Ericsson´s PBL 3773/1. While several of Ericsson´s dual stepper motor drivers are optimized for micro-stepping applications, PBL 3775/1 is equipped with a disable input to simplify half-stepping operation.
The PBL 3775/1 contains a clock oscillator, which is common for both driver channels, a set of comparators and flip-flops implementing the switching control, and two output H-bridges, including recirculation diodes.
Voltage supply requirements are + 5 V for logic and + 10 to + 45 V for the motor. The close match between the two driver channels guarantees consistent output current ratios and motor positioning accuracy.
Key Features
• Dual chopper driver in a single package.
• Operation down to -40°C.
• 750 mA continuous output current per channel.
• Low power dissipation, 2.0 W at 2 x 500 mA output current.
• Close matching between channels for high microstepping accuracy.
• Digital filter on chip eliminates external filtering components.
• Plastic 22-pin batwing DIL package, 24-pin SOIC batwing or 28-pin power PLCC. All with lead-frame for heatsinking through PC board copper.
