TMP816 具有软启动的变速单相全波风扇电机前置驱动器

The TMP816 is a single-phase bipolar variable-speed fan-motor predriver that works with an external PWM signal. A highly efficient, quiet and low power consumption motor driver circuit with a large variable speed can be implemented by adding a small number of external components.

This device is optimal for driving large-scale fan motors (with large air volume and large current) such as those used in servers and consumer products

TMP816 特性

• Pre-Driver for Single-Phase Full-Wave Drive
  • PNP-NMOS is used as an external power TR,
    enabling high-efficiency low-consumption drive by
    means of the low-saturation output and single-phase
    full-wave drive. (PMOS-NMOS also applicable)
• External PWM Input Enables Variable-Speed Control
  • Separately-excited upper direct PWM (f = 25 kHz)
    control method, enabling highly silent speed control
• Current-Limiter Circuit
  • Chopper-type current limit at start
• Reactive Current-Cut Circuit
  • Reactive current before phase change is cut to
    enable silent and low-consumption drive
• Minimum Speed Setting Pin
  • Minimum speed can be set with external resistor. The start
    assistance circuit enables start at extremely low speed.
• Constant-Voltage Output Pin for Hall Bias
• Lock Protection and Automatic Reset Functions
• Rotation Speed Detection (FG) and Lock Detection (RD) Outputs
