Motor Drivers

The AP1029ADN is a 1ch H-Bride Motor Driver characterized by generating a constant motor torque, a built-in Start-Up function and a small package. The H-bridge of the AP1029ADN employs the P-N construction that eliminates the need for charge pump reducing the external parts, and its low on-resistance realizes high efficiency while keeping low consumption.
An anomaly detection output pin, under voltage detection circuit, thermal shut down circuit and over-current protection circuit are integrated. These functions will improve reliability of the system.
The AP1029ADN is the product of the general-purpose H-bridge motor driver AP102x series.


□Constant Motor Torque
The AP1029ADN is suitable for various systems by supporting a wide range application voltage (5.5V to 32V) and it operates off of a single power supply with an internal 4.5V regulator. In addition, the AP1029ADN has PWM Duty Control that adjusts duty automatically if the power supply voltage is changed. Therefore a constant motor torque can be provided even when the battery voltage drops.

□Start-up Function
The drive method of start-up operation can be selected either duty cycle of 0% or 100%.

The AP1029ADN is housed in an ultra-small 16-pin QFN package (3mm×3mm).
