PBL3776-1 - Dual Controller IC for High Current Stepper Motor Applications

Description

The PBL 3776/1 is a switch-mode (chopper), constant-current controller IC intended for controlling external transistors in a high current stepper motor application.The IC has two channels one for each winding of a two-phase stepper motor.

The circuit is similar to Ericsson´s PBL 3775/1.

Features

Suitable to drive any external Mos Fet or bipolar power transistor.
0°C to +85°C operation.
Few external components.
Crossconduction prevented by time delay.
Close matching between channels for high positioning accuracy.
Digital filter on chip eliminates external filtering components.
Plastic 24-pin "narrow" DIP package. Phase 1 Dis 1 V R1 C1 SGND 1 Pwr GND 1 1 PBL 3776/1.

February 1999 PBL 3776/1 Dual Controller IC for High Current Stepper Motor Applications Description The PBL 3776/1 is a switch-mode (chopper), constant-current controller IC intended for controlling external transistors in a high current stepper motor application.The IC has two channels one for each winding of a two-phase stepper motor. The circuit is similar to Ericsson´s PBL 3775/1. PBL 3776/1 is equipped with a Disable input to simplify half-stepping operation. The PBL 3776/1 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 sections each containing four outputs, two source and two sink, intended to drive an external H-bridge.
