TOSHIBA Bi-CD Integrated Circuit Silicon Monolithic TB67S158NG
Constant voltage control DMOS driver incorporating 2 function modes (full parallel input and
Summary The TB67S158 is a constant voltage control DMOS driver. It can operate
maximum of two unipolar stepping motors (max).
MODE1: Full parallel input (similar to transistor array)
MODE2: Serial input NG Output voltage of 80V and maximum current of 1.5A are realized by
applying BiCD process. Motor can be driven by single power supply of
VM with the internal regulator. P-SDIP24-0723-1.78-001 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
・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
・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 TB67S158NG
