NG
maximum of two unipolar stepping motors (max). MODE1: Full parallel input (similar to transistor array) MODE2: Serial input Output voltage of 80V and maximum current of 1.5A are realized by P-SDIP24-0723-1.78-001 applying BiCD process. Motor can be driven by single power supply of VM with the internal regulator. Weight: 1.4g(typ.)
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. Note) Please be careful about the thermal conditions during use. ©2014 Toshiba Corporation 1 2015-5-11
