KA44169ABVB(T)

Product Description

KA44169AB 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 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. It has input pin that can be connected to DC voltage to control the speed of the motor. There is one mode select pin which can be used to select the startup assist function which allows the motor to start at 50% duty to further increase the efficiency of the operation. It needs a hall element to get the speed of the motor and set the output levels. To control the motor with PWM, it has a Triangle wave capacitor connection pin for PWM duty & frequency.
