AP1029ADN
32V H-Bridge DC Motor Driver IC
1. General Description
The AP1029ADN is a 1ch H-Bridge motor driver that corresponds to an operating voltage of 32V. Four
drive modes, which are forward, reverse, brake, and standby are available. An N-ch MOSFET is located at
low side and a P-ch MOSFET is located at high side of the output block. The output voltage can be
controlled externally or by PWM input signal. Since the AP1029ADN utilizes internal regulator outputs as
control power, it can be operated by a single power supply so that external components are able to be
reduced. It also features an under voltage lockout circuit, a thermal shutdown circuit and an over-current
protection circuit.
