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
