TB67S105FTG

Toshiba BiCD Process Integrated Circuit Silicon Monolithic TB67S105FTG 8bit Serial controlled bipolar stepping motor driver 1. Outline The TB67S105FTG is a two phase bipolar stepping motor driver using a PWM chopper, controlled by 8-bit serial data. Fabricated by the BiCD process, the TB67S105FTG is rated at 50 V/3.0 A. The internal voltage regulator allows to control the device with a single VM power supply. TB67S105FTG P-WQFN48-0707-0.50-003 Weight: 0.12 g (typ.) 2. Features  BiCD process integrated monolithic IC.  Capable of controlling one bipolar stepping motor.  Low on-resistance MOSFET output stage.  High voltage and current (for specification, please refer to the absolute maximum ratings and operation ranges).  Built-in serial-parallel convert circuit (8bit shift register)  3-line (Data, Clock, Latch) serial output function for cascade connection  PWM controlled constant-current drive.  Allows full and half step operation  4 bit (16 steps) adjustable torque function (TRQ1, TRQ2, TRQ3, TRQ4).  Built-in error detection circuits (Thermal shutdown (TSD), over current shutdown (ISD), and power on reset(POR)).  Built-in VCC regulator for internal use.  Chopping frequency of a motor can be customized by external resistor and capacitor.  Package type: P-WQFN48-0707-0.50-003 Note: Please be careful about thermal conditions during use. © 2012-2024 1 Toshiba Electronic Devices & Storage Corporation 2024-04-05 Rev.1.1 3.
