TB67S539FTG

TB67S539FTG Toshiba BiCD Process Integrated Circuit Silicon Monolithic TB67S539FTG BiCD Constant-Current Two-Phase Bipolar Stepping Motor Driver IC The TB67S539FTG is a two-phase bipolar stepping motor driver using a PWM chopper. Fabricated with the BiCD process, the TB67S539FTG is rated at 40V/2.0A (Absolute maximum ratings). A stepping motor can be operated with a single VM power supply by built-in regulator. Features  BiCD process monolithic IC. P-VQFN32-0505-0.50-004 Weight: 0.066 g (typ.)  Capable of controlling 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.  Operational in full, half, quarter, 1/8, 1/16, and 1/32 step resolutions.  BiCD process: Use DMOSFET for the output power transistor.  High withstand voltage and large current drive: 40 V / 2.0 A (Absolute maximum ratings).  Built-in thermal shutdown (TSD), over-current detection (ISD), and under voltage lockout (UVLO).  External components for a charge pump are reduced.  Package: QFN32 (5 mm × 5 mm). 1 © 2021 Toshiba Electronic Devices & Storage Corporation Start of commercial production 2021-08 2021-03-05 Ver1.0 Pin Assignment TB67S539FTG (Top View) TB67S539FTG TRQ1 TRQ0 NC CLK ENABLE CW_CCW DECAY2 DECAY1 DMODE0 DMODE1 DMODE2 OSCM MO PGND NC NC 24 23 22 21 20 19 18 17 ...
