Product description

          AT9110 is a dual-channel push-pull power amplifier dedicated integrated circuit device designed for controlling and driving motors. It integrates discrete circuits in a single-chip IC, which reduces the cost of peripheral devices and improves the overall reliability. The input end of the chip is compatible with TTL / CMOS level and has good anti-interference performance; the two output ends can directly drive the forward and reverse movement of the motor, it has a large current driving capability, and each channel can pass a continuous 750mA ~ 800mA Current and peak current capability can reach 1.5A ~ 2A; the built-in clamping diode can release the reverse impact current of the inductive load, making it safer and more reliable for driving relays, DC motors, stepper motors or switching power tubes. AT9110 is widely used in toy car motor drive, stepper motor drive and switching power tube circuits.
