AH292 datasheet

Description

AH292 is a monolithic fan motor controller with Hall sensor’s capability. It contains two complementary open-collector transistors for motor’s coil driving, automatic lock current
shutdown, and recovery protections. In addition a Frequency generator (FG) output is also available for speed detection.

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: 1.8V to 5.75V

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

8. Green Molding Compound

Description

The aim of this design guide is to assist the designer through the steps needed to complete a design using the C2183 power controller. The primary side sensing (PSS) controller is designed to drive an external power MOSFET switch in a Discontinuous Current Mode (DCM) quasi-resonant flyback converter. The block diagram for the IC is shown in Figure 1. A generic circuit diagram of a converter is shown in Figure 2 below. Use this document in conjunction with the C2183 datasheet, which lists the IC parametric values. The C2183 is a primary sensing switching regulator. It is intended for applications where constant voltage and current operation is required. […]

Features

1. Advanced primary sensing control circuitry achieves accurate voltage and current (CV and CC) regulation without an opto-coupler

2. Optimised PWM/PFM with quasi resonant switching enables efficiency standards compliance with margin

3. Switching frequency dither eases design for low EMI

4. Inherently low ripple

5. Best in class load-transient performance

6. No-load power less than 100 mW
