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

The TB62202AF/AFG 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 (T

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, V

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.

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.
