The Texas Instruments TMP814PWR is a single-phase bipolar variable speed fan motor predriver. It is designed to work with an external PWM signal to implement a highly efficient, quiet, and low-power consumption motor driver circuit. This device is optimal for driving large-scale fan motors used in applications such as servers and consumer products.
Key electrical specifications include an operating voltage range of 6V to 16V and a PWM control interface. The device is housed in a 20-TSSOP package and is designed for surface mount applications.
The TMP814 is compatible with 12V, 24V, and 48V power supplies and incorporates features like rotor lock protection and tach/FG feedback. Its control topology is sensored and trapezoidal, with a control interface of 1xPWM.
This predriver utilizes PNP-NMOS as an external power transistor, enabling high-efficiency, low-consumption drive through low-saturation output and single-phase full-wave drive. It also includes a current limiter circuit, reactive current cut circuit, minimum speed setting pin, and start assistance circuit for enhanced performance and silent operation.
