TMP816
- Predriver 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)
- PNP-NMOS is used as an external power TR,
- External PWM Input Enables Variable-Speed Control
- Separately-excited upper direct PWM
(f = 25 kHz) control method, enabling highly
silent speed control
- Separately-excited upper direct PWM
- 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
- Reactive current before phase change is cut to
- Minimum Speed Setting Pin
- Minimum speed can be set with external
resistor. The start assistance circuit enables
start at extremely low speed.
- Minimum speed can be set with external
- Constant-Voltage Output Pin for Hall Bias
- Lock Protection and Automatic Reset Functions
- Rotation Speed Detection (FG) and Lock
Detection (RD) Outputs
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.
The TMP816 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.
