AH5772
Description
The AH5772 is a single chip solution for driving single-coil brushless direct current (BLDC) fans and motors. The integrated full-bridge driver output stage uses soft switching to minimize audible switching noise and electromagnetic interference (EMI) providing a low noise solution.
Key Features
- Supports Single-phase Full Wave BLDC Fan/Motor Drive
- Wide Operating Voltage Range: 2.4V to 18V
- Built-in High Sensitivity Hall Effect Sensor
- Very Low Temperature and Voltage Coefficient of the Magnetic Operating Switch Points
- Built-in H-Bridge with Low RDSON Resistance
- Soft Switching for Low Noise DC Fan Motor Applications
- Rotor Lock Protection (Lock Detection, Output Shutdown and Automatic Re-start)
- Over Voltage Shutdown
- Thermal Protection
- No External Timing Capacitor - Reduces the Numbers of External Components Required
