TB67S149FG

Toshiba BiCD Process Integrated Circuit Silicon Monolithic

TB67S149FG

Clock controlled Unipolar stepping motor driver

The TB67S149FG is a Clock controlled PWM chopping type 2 phase unipolar

stepping motor driver. Using the BiCD process, the TB67 S149FG can be

of operated with VM voltage of 45 V, output voltage of 84 V, and output current

3.0 A at max (absolute maximum ratings).

P-HSSOP28-0819-0.80-001

Features

・BiCD processed monolithic integrated circuit.

・Capable of operating one unipolar stepping motor.

・PWM controlled current sense resistance-less constant current drive .

・Full, half(a), half(b), quarter, 1/8, 1/16, 1/32 step resolution.

・Low on resistance(0.25 Ω (Typ.) output MOSFET.

Weight: 0.88 g (Typ.)

・High voltage and current (For specification, please refer to the absolute maximum ratings and operation ranges).

・Standby (low power) mode function

・Error detect feedback signal output function (Over current/Thermal shutdown).
