TB67S539FTG
TB67S539FTG is BiCD Constant-Current Two-Phase Bipolar Stepping Motor Driver manufactured by Toshiba.
Features
- Bi CD 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.
- Bi CD 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 ponents for a charge pump are reduced.
- Package: QFN32 (5 mm × 5 mm).
