TB67S158FTG TOSHIBA Bi-CD Integrated Circuit Silicon Monolithic
TB67S158FTG 1. Summary/Features/Appearance Constant voltage control DMOS driver incorporating 3 function modes (full parallel input, clock input, and serial input) and a large mode. Summary FTG
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: CLK input MODE3: Serial input MODE4: Large mode Output voltage of 80V and maximum current of 1.5A are realized by P-WQFN48-0707-0.50-003

applying BiCD process. Motor can be driven by single power supply of VM with the internal regulator. Weight: 1.1g (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) ・Full brake (all-phase excitation) mode function (enable only for CLK mode and Large mode) ・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 (disenable in CLK mode) Note) Please be careful about the thermal conditions during use. 1 2015-3-3 ©2014 Toshiba Corporation
