KA44169A-VB(T)

Product Description

KA44169A 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. It also has PWM input pin which can be used to set the speed of the motor connected. It is available in TSSOP 14L package which is having a height of only 0.9mm making it suitable for small form factor appliance and applications. It can work for appliances running on 12V/24V voltage rating and with Ron of 1.6Ohms, it can be very efficient in operating conditions. It comes with a complete set of protections like Under Voltage Lock Out (UVLO), Over Voltage Lock Out (OVLO), Thermal protection and a Current limit Protection which adjustable by connecting an external resistor thus customizing the driver to the need.

Basic Specification

Applications

Refrigerator, Projector, Printer, Factory automation. It is easy to connect in a driver circuit as there are not much peripheral components required. The PWM control also makes it easier to control the speed of the motor. It requires an external Hall Element to read the speed and orientation of the motor.
