AN44169A

Doc No. TA4-EA-06318 Revision. 3 Product Standards AN44169A Driver IC for single phase Brushless Motor FEATURES  Supply voltage range: 5.0 V ~ 28 V  Auto phase shift correction with built-in Soft Switching function  Wide range operation (12V/24V)  Speed Control by direct PWM input  Motor lock protection and built-in Auto-recovery Adjustable by a external capacitance  Output pin for FG pulse (open drain)  Output pin for lock detection (open drain )  Various protection functions: Under Voltage Lock Out (UVLO), Thermal protection GND short protection, and Over Current Protection Package : SO type 14pin(0.65mm pitch) DESCRIPTION  AN44169A is a high efficiency single phase motor driver IC with built-in Soft Switching function for low noise operation. The soft switching period is automatically adjusted based on the motor current. This eliminates the need for individual adjustment of the soft switching period based on the Motor’s specifications.  With a ...
