Brushless motor driver IC
TB6581HG TOSHIBA Bi-CMOS Power Integrated Circuit Multi-Chip Package (MCP)
TB6581HG 3-Phase Full-Wave Sine-Wave PWM Brushless Motor Controller
The TB6581HG is a high-voltage PWM BLDC motor driver. The product integrates a sine-wave controller and
the TPD4103AK high-voltage driver in a single package (“2-in-1”).
It is designed to change the speed of a BLDC directly motor by
using a speed control signal (analog) from a microcontroller.
Features A sine wave PWM drive controller and a high-voltage driver
integrated in a single package. IGBTs arranged in three bridge units Triangle wave generator (carrier frequency = fosc/254 (Hz)) Dead-time insertion (1.9 µs) High-side bootstrap supply Bootstrap diode Overcurrent protection, thermal shutdown, and undervoltage lockout On-chip regulator (Vreg = 7 V (typ.), 30 mA (max),
Vrefout = 5 V (typ.), 30 mA (max)) Operating power supply voltage range: VCC = 13.5 to 16.5 V Motor power supply operating voltage range: VB = 50 to 400 V
Weight: 7.7 g (typ.)
