Description
PBL 3770A is a bipolar monolithic circuit intended to control and drive the current in
one winding of a stepper motor. It is a high power version of PBL 3717 and special
care has been taken to optimize the power handling capability without suffering in
reliability.
The circuit consists of a LS-TTL compatible logic input stage, a current sensor, a
monostable multivibrator and a high power H-bridge output stage. The circuit is
pin-compatible with the PBL 3717 industry-standard driver.
Two PBL 3770A and a small number of external components form a complete
control and drive unit for LS-TTL or microprocessor-controlled stepper motor
systems.
Key Features

5 -1800 mA.
Wide voltage range 10 - 45 V.
Designed for unstabilized motor
supply voltage.
Current levels can be selected in
steps or varied continuously.
Thermal overload protection.
