US72 General Description
The US72 and US73 provide a monolithic solution for driving single-coil fans. The bridge drivers provide bi-directional current through the single phase motor winding.
US72: The tachometer/Frequency Generator (FG) version produces a logic signal, which is aligned with the Hall plate signal.
US73: The Rotation Detector (RD) / Alarm Signal version has a low output in the normal condition. When a locked rotor condition occurs the RD changes to a high state.
US72 Maximum Ratings
| Supply Voltage, VDD (overvoltage) | 28V |
| Output Voltage, FG or RD | 28V |
| Output Current, IOUT | 500mA |
| Operating Temperature Range, TA | -40 to 85 |
| Junction Temperature, Tj | 125 |
| Storage Temperature, Ts | -55 to 150 |
| ESD Sensitivity (AEC Q100 002) | 2KV |
| Magnetic Flux Density | No limit |
Exceeding the absolute maximum ratings may cause permanent damage. Exposure to absolutemaximum-rated conditions for extended periods may affect device reliability.
US72 Features
· Full Bridge Driver
· High Sensitivity Hall Sensor
· Locked Rotor Shutdown and Auto-Restart
· Power-Efficient CMOS and Power MOSFETs
· Integrated tachometer (US72) or alarm (US73) signal outputs
· High Sensitivity Hall Sensor
· Locked Rotor Shutdown and Auto-Restart
· Power-Efficient CMOS and Power MOSFETs
· Integrated tachometer (US72) or alarm (US73) signal outputs
US72 Typical Application
· For 12V/24V Fans
