TPD4131K is a high-voltage PWM DC brushless motor driver. It is an integrated circuit with a high-side drive circuit, a low-side drive circuit, a PWM circuit, a three-phase distribution circuit, a level shift high-side driver, overcurrent protection, over-temperature protection, undervoltage protection, and FRD. It is driven by Hall sensor/Hall IC and microcontroller to directly drive DC brushless motor to achieve variable speed.
The TPD4131K is a high‑voltage PWM brushless motor driver IC using a SOIT process. It integrates PWM circuitry, three‑phase distribution, level‑shift high‑side and low‑side drivers, over‑current, over‑temperature and undervoltage protection, and an IGBT full‑bridge output, allowing direct speed control of DC brushless motors via Hall‑sensor inputs or microcontroller control.
