Description
The PBL3771/1 is a switch-mode, constant-current driver IC designed for use in microstepping applications with a two-phase stepper motor. It is equipped with two channels, each dedicated to one winding of the motor. To achieve microstepping, the PBL3771/1 is designed to work in conjunction with the dual DAC PBM3960. Together, these two ICs, along with a few passive components and a microprocessor, form a complete driver system for precise control and data codes required for microstepping.
Specifications and features
The PBL3771/1 boasts the following key features:
- Dual chopper driver in a single package
- Output current per channel: 650 mA
- High microstepping accuracy due to close matching between channels
- Selectable slow/fast current decay for improved high-speed microstepping
- Improved low-level linearity
- Specially matched to Dual DAC PBM3960
- Available in different packages: 22-pin "batwing" DIP, 24-pin "batwing" SOIC, or 28-lead PLCC with a lead-frame for heat sinking through PC board copper
Application Scenarios
The PBL3771/1 and the dual DAC PBM3960 are designed specifically for microstepping applications in two-phase stepper motors. These ICs, along with the necessary passive components and a microprocessor, enable precise control and positioning in various industries and applications, such as robotics, automation, CNC machines, and 3D printers.
