Details
Dual-Stepping Motor Driver IC for OA Equipment Using PWM Chopper Type The TB62202AFG 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.The IC supports Mixed Decay mode for switching the attenuation ratio at chopping. The switching time for the attenuation ratio can be switched in four stages according to the load. Features● Two stepping motors driven by micro−step pseudo sine wave are controlled by a single driver IC● Monolithic Bi-CMOS IC● Low ON-resistance of Ron = 1.2 Ω (Tj = 25°C @1.0 A: Typ.)● Two pairs of built-in 16-bit shift and latch registers● Two pairs of built-in 4-bit DA converters for micro steps● Built-in ISD, TSD, VDD and VM power monitor (reset) circuit for protection● Built-in charge pump circuit (two external capacitors)● 36-pin power flat package (HSOP36-P-450-0.65)● Output voltage: 40 V max● Output current: 1.0 A/phase max● Built-in Mixed Decay mode enables specification of four-stage attenuation ratio. (The attenuation ratio table can be overwritten externally.)● Chopping frequency can be set by external resistors and capacitors. High-speed chopping possible at 100 kHz or higher.
