TB62269FTG

TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB62269FTG TB62269FTG PWM method CLK-IN bipolar stepping motor driver The TB62269FTG is a two-phase bipolar stepping motor driver using a PWM chopper. Fabricated with the BiCD process, the TB62269FTG is rated at 40 V/1.8 A . The internal voltage regulator allows control of the motor with a single VM power supply. Features Drive control is possible in a bipolar stepping motor at 1 chip. PWM controlled constant-current drive Allows full, half and quarter ,1/8,1/16,1/32 step resolutions. P-WQFN48-0707-0.50-003 Low on-resistance of output stage transistor is low by using BiCD process. High Voltage and current (For specification, please refer to absolute Weight:0.14g(Typ.) maximum ratings and operation ranges) Thermal shutdown (TSD)、over-current shutdown (ISD), and power-on reset of VM power supply (POR) Built-in regulator allows the TB62269FTG to function with only VM power supply. Able to customize PWM signal frequency by external resistance/capacitor.
