10. Control Logic
The AP1017 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 AP1017 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.
