AT9110A
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. Characteristic Low quiescent operating current Wide power supply voltage range: 2.5V-18V 800mA continuous current output capability per channel Lower saturation voltage drop Output has three states: forward, reverse, and high impedance TTL / CMOS output level compatible, can be directly connected to the CPU Built-in output diodes for inductive loads Control and drive are integrated into a single IC with pin high voltage protection 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. Operating temperature range: -20 ℃ ~ + 80 ℃ SOP8, DIP8, SIP8 package typical application Motor-driven toys Code lock, safe (code lock motor control) Water meter and gas meter Home appliances |
