Product details

Description

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.

Features

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. V C.
