TA8068F
TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC
TA8068F
Intelligent Stepping Motor Driver
The TA8068F is a stepping motor driver with a current capacity
of 1.5A. Inputs INA and INB are combined to control the four
outputs.
Since the inputs are TTL-compatible, this IC can be controlled
directly from a CPU or other control system.
The IC also incorporates various protective functions as well as a
self-diagnostic function for diagnostic function for diagnostic
output.
FEATURES
· Output current capacity : 1.5 A (max)
· Low standby current : 0.1 mA (max)
Weight: 0.79 g (typ.)
· Built−in Protective Functions : Over-Voltage Protection/ Short-Circuit Protection(latch) / Thermal-Shutdown
· Self−diagnostic Output : On Short-Circuit Detection
· Recommended operating supply voltage range : VCC = 8~16 V
· Separate GND for output and logic control sections
· HSOP20-Pin Power Flat Pakage
