PT-30DFB is a DC brushless motor driver IC suitable for single-coil DC brushless motors. It features a single-phase full-wave driver, motor lock protection and automatic restart, connectable directly to Hall elements, built-in hysteresis comparator, frequency generation output, rotate detection (alarm) output, low power consumption, and high driving efficiency.
The document describes the Prolific Technology Inc. PT-30DFB, a DC Brushless Motor Driver IC designed for driving single-coil DC brushless motors with supply voltages between 2.0V and 18V. The device is packaged in an MSOP-8 package.
| Supply Voltage Range | 2.0V ~ 18V |
|---|---|
| Package Type | MSOP-8 |
| Allowable Power Dissipation | 450 mW |
| Operating Temperature Range | -30 ~ +100 C |
| Output Current (Continuous) | 400 mA |
The driver IC generates a square wave to indicate the motor rotation frequency.
The driver IC shuts down and restarts after 2.1 seconds.
