Description

        AT9110A 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 reliability of the whole machine. 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 750-800mA. Current and peak current capacity can reach 1.5 ～ 2.0A; the built-in clamping diode can release the reverse impact current of the inductive load, making it safe and reliable in driving relays, DC motors, stepper motors or switching power tubes. The chip integrates a thermal shutdown protection function module. When it detects that the chip pn junction temperature exceeds a threshold, it shuts down all circuit module functions. AT9110A is widely used in toy car motor drive, stepper motor drive and switching power tube circuits.
