TB62200AF

The TB62200AF is a dual-stepping motor driver driven by chopper micro-step pseudo sine wave.To drive two-phase stepping motors,two pairs of 16-bit latch and shift registers are built in the IC.The IC is optimal for driving stepping motors at high efficiency and with low-torque ripple.

Features of the TB62200AF are:(1)chopping bipolar stepping motor driver;(2)two stepping motors driven by micro-step psedudo sine wave are controlled by a single driver IC;(3)monolithic Bi-CMOS IC;(4)low ON-resistance of RDS(on)=0.5(@Tj=25,1.0A:Typ.);(5)two pairs of built-in 16-bit shift and latch registers;(6)two pairs of built-in 4-bit D/A converters for micro steps;(7)built-in TSD,VDD & VM power monitor (reset) circuit for protection;(8)built-in charge pump circuit;(9)36-pin power flat package;(10)output voltage is 30V max;(11)output current is 1.3A/phase max;(11)built-in mixed decay mode and slow decay mode;(12)chopping frequency can be set by external resistors and capacitors.High-speed chopping possible at 100kHz or higher.
