Dual-Stepping Motor Driver IC for OA Equipment Using PWM Chopper Type
The TB62201AFG 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

z Low ON-resistance of Ron = 0.5 Ω (T_j = 25°C @ 1.0 A: typ.)
z ESD protection Exceeds 2000 V, MIL-STD-883D
z Two pairs of built-in 16-bit shift and latch registers
z Two pairs of built-in 4-bit DA converters for micro steps
z Built-in ISD, TSD, V_DD&V_M power monitor (reset) circuit for protection
z Built-in charge pump circuit (two external capacitors)
z 36-pin power flat package (HSOP36-P-450-0.65)
z Output voltage: 40 V max
z Output current: 1.5 A/phase max
z Built-in Mixed Decay mode enables specification of four-stage attenuation ratio.
(The attenuation ratio table can be overwritten externally.)
z Chopping frequency can be set by external resistors and capacitors. High-speed chopping possible at 100 kHz or
higher.
Note:
When using the IC, pay attention to thermal conditions.
These devices are easy damage by high static voltage.
In regards to this, please handle with care.
