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 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
applying BiCD process. Motor can be driven by single power supply of
VM with the internal regulator. FTG P-WQFN48-0707-0.50-003
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 …
