| Chip Description: The PT392V-A is a variable-speed DC fan motor driver IC with a built-in Hall sensor. Its integrated dynamic offset cancellation enables optimal symmetric magnetic sensing. The output driver provides a linear driver to eliminate switching noise. In addition, the linear drive of the PT392V-A will be beneficial to the performance of Baidai (Note: If "百代代" is a brand/module name, it is recommended to confirm the official English name; if it is a translation error, please provide the correct Chinese term for adjustment). This integrated circuit is the optimal solution for PWM speed control in automotive brushless DC fan motor applications. |
Pin Description： TSOT-6pin (2.9x1.6x0.75mm) DFN-8pin (2x2x0.75mm) Chip Applications:
| 5V/12V Applications
D1: Schottky diode. D2: Zener diode. Q1: NPN transistor. R1: Recommend 1K ohm. R2: PWM resistor 15K ohm. C1: Decoupling capacitor 1.0uF ~ 2.2uF PS. R1, Q1, and D2 are used for overvoltage protection. If VIN (power supply) can be stabilized within 18V, the part can be saved. |
