Toshiba TB67S539FTG Bipolar Stepping Motor Driver IC

Toshiba TB67S539FTG Bipolar Stepping Motor Driver IC is a two-phase bipolar stepping motor driver implementing a PWM chopper. The TB67S539FTG has a 40V/2.0A absolute maximum rating utilizing the BiCD process. The TB67S539FTG stepping motor can be operated with a single VM power supply by a built-in regulator. The device is housed in a QFN32 5mm x 5mm package and reduces external components.

Features

BiCD process monolithic IC
Capable of controlling the bipolar stepping motor
Advanced Current Detect System (ACDS) realizes a PWM constant-current control without external current detection resistors
Advanced Dynamic Mixed Decay (ADMD) realizes a high-efficiency PWM constant-current control
Clock input control
External components for a charge pump are reduced

Operational in full, half, quarter, 1/8, 1/16, and 1/32 step resolutions
BiCD process: Use DMOSFET for the output power transistor
