AH288 datasheet

Description

AH288 is a monolithic fan motor controller with Hall sensor’s capability. It contains two complementary open-drain transistors as motor coil drivers, automatic lock current shutdown, and recovery protections. Additional, frequency generator (FG) output is for speed detection relatively.

Rotor-lock shutdown detection circuit turns off the output driver when the rotor is blocked to avoid coil overheat. Then, the automatic recovery circuit will restart the motor. These protected actions are repeated and periodic during the blocked period. Until the blocking is removed, the motor recovers and runs normally.

Features

1. On chip Hall sensor

2. Rotor-locked shutdown

3. Automatically restart

4. Frequency generator (FG) output

5. Built-in Zener protection for output driver

6. Operating voltage: 3.8V~28V

7. Output current: IO(AVE)= 400mA

8. Lead Free Finish / RoHS Compliant

Description

OZ9928 is a high performance, cost-effective 2-channel controller designed for large-size Cold Cathode Fluorescent Lamp (CCFL) or External Electrode Fluorescent Lamp (EEFL) Liquid Crystal Display Television (LCD TV) applications.

The controller provides six drive signals and is capable of driving full-bridge and Class-D topologies. The drive outputs are fixed phase when used for single-side or differential drive applications. Multiple OZ9928s can be synchronized to drive numer ous lamps.

OZ9928 provides total system protection for differential drive and single-side drive applications.
