[AP1041] AP1041 32V 1ch H-Bridge Motor Driver IC
1. General Description
The AP1041 is a 1ch H-Bridge motor driver that supports a maximum output current of 1.0A and from 8
to 32V operation voltage. The control mode of the AP1041 can be switched between parallel input mode
and complemental input mode by the SEL pin. The built-in PWM duty control circuit enables speed
adjustment of the motor by the VREF voltage for both forward and reverse rotations. The AP1041 has a
through current prevention, a low voltage detection, a thermal protection and an overcurrent protection
circuits for the output stage as protection circuits. The detection time of the overcurrent protection circuit
can be adjusted by the resistance value connected to the TBLANK pin.
The AP1041 adopts a space saving 24-pin QFN package with good heat dissipation. It is ideal for a high
current DC brush motor driver IC. 2. Features
