AH5775
Overview
The AH5775 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.
- Supports single-phase full wave BLDC fan/motor drive
- Built-in Hall effect sensor and input amplifier
- Operating voltage: 2.5V to 18V
- Soft switching for low noise DC fan motor applications
- Rotor Lock Protection (Lock detection, output shutdown and automatic restart)
- Overvoltage shutdown
- Thermal protection
- No external timing capacitor - Reduces the numbers of external components required
- Industry Standard TO94 Package
- Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)
