AP1015BEN
10.5V 1ch H-Bridge Motor Driver IC
1. Overview
The AP1015BEN has four drive mode of forward, reverse, brake and standby by 1 channel H-bridge Motor
Driver corresponding to operating voltage 10.5V. The AP1015BEN layouts P-channel MOSFET for high
side and N-channel LDMOSFET for low side in output circuit. This realizes a small package and less
external parts. Under voltage detection and thermal shut down circuits are implemented. It is suitable for
driving various small motors.

10. Control Logic
The AP1015BEN is suitable to drive DC motor and voice coil motor. If the input signals are fed to INA and
INB, the output signals, OUTA and OUTB are decided as Table 1.The AP1015BEN includes Under Voltage
Lock Out (UVLO) and Thermal Shut Down (TSD) circuits. The UVLO circuit monitors the control voltage
(VC). If the VC is less than the specified voltage, the output of the H-bridge goes to high impedance. The
TSD circuit monitors the chip temperature. If the temperature of the chip exceeds specified temperature, the
output of the H-bridge goes to high impedance. UVLO circuit and TSD circuit have hysteresis levels.

Note 9. In standby mode, all the circuits include the TSD circuit are stopped.
The TSD circuit may not operate in the PWM operation which repeats CW(CCW) → standby.
It is recommended to use PWM operation with CW(CCW) → brake.
