Constant voltage control DMOS driver incorporating 2 function modes (full parallel input and serial input).

Features

・Capable of operating maximum of two 2-phase unipolar stepping motors by one chip.

・High voltage and current (as for specifications, please refer to the absolute maximum ratings and operation

ranges).

・Low on resistance (Ron=0.5Ω (typ.)) of output step is realized by BiCD process.

・Built-in VCC regulator for internal circuit control (capable of operating by only VM power supply)

・Capable of constant voltage driving (corresponding to 2-phase and 1-2-phase excitation drives)

・Built-in thermal shutdown circuit (TSD), over current detection (ISD), and power on reset of VM power

supply.

・ALERT signal can be outputted to outside when thermal shutdown circuit (TSD) or over current detection

(ISD) operates.
