These ICs are offered in three package types: PDIP, SOIC, and TSSOP. They provide a variety of step modes, selectable through three mode inputs, including full, 1/2, 1/4, 1/8, 1/16, and 1/32. The ICs support peak current feedback control using pulse width modulation chopping, applicable in both full-step and half-step modes. Control over the 8-bit PWM resolution and the refresh rate (typically 31.25kHz) is achieved through an internal oscillator, which can be controlled by a crystal or an external input clock. The PWM chopper circuit for current control consists of a voltage comparator, flip-flop, and external sense resistor.
Note: Items in this series have a Minimum Purchase Requirement of 10 pieces, regardless of stock.
