TB62269FTAG TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB62269FTAG PWM method CLK-IN bipolar stepping motor driver The TB62269FTAG is a PWM chopper type clock-in controlled motor driver for two-phase bipolar stepping motor. Fabricated with the BiCD process, the TB62269FTAG is rated at 40 V/1.8 A . The internal voltage regulator allows control of the motor with a single VM power supply. Features Bipolar stepping motor driver PWM controlled constant-current drive P-VQFN32-0505-0.50-004 Clock input control Allows full, half, quarter ,1/8,1/16, and 1/32 step resolutions Weight: 0.11g (Typ.) Low on-resistance of output stage by using BiCD process High Voltage and large current (For specification, please refer to absolute maximum ratings and operation ranges.) Thermal shutdown (TSD), over-current shutdown (ISD), and power-on reset (POR) Built-in regulator allows the TB62269FTAG to operate with only VM power supply. Able to customize chopping frequency by external resistance and capacitor. Packages: P-VQFN32-0505-0.50-004 Note: Please be careful about thermal conditions during use. 1 2016-9-27 2016 TOSHIBA CORPORATION Ver1.0 TB62269FTAG 1.
