DC motor single-channel H-bridge driver chip SOP / DIP8 series

describe HR1124S / HR1154D is a single-channel H-bridge driver chip applied to a DC motor scheme. The HR1124S / HR1154D h-bridge drive portion uses a PMOS and NMOS power tube of low-conducting resistance. The low-conducting resistance ensures low power loss of the chip, so that the chip is safe to work longer. In addition, HR1124S / HR1154D has a low standby current, low static operating current. These properties enable HR1124S / HR1154D easy to use for a toy solution. The HR1124S / HR1154D inside the HR1124S / HR1154D contains overwhelming interrupt protection. When the load motor is low impedance, or the output is shorted, so that the output current of HR1124S / HR1154D has risen sharply, and the internal temperature has risen sharply. When the chip temperature exceeds the maximum temperature threshold (typically 150 ° C), HR1124S / HR1154D will turn off all output to prevent potential security hazards. Only when the chip returns to the safe operating temperature, the built-in temperature hysteresis current reacts the drive circuit. application Lithium battery power supply DC motor drive Toy robot drive control, etc. Model selection Part Number Package HR1124S SOP 8 HR1154D DIP 8 Characteristics ● Built-in PMOS, NMOS single-channel H-bridge driver ● Four drivers: orthography, reverse, stop and brake function ● Low RDS (ON) resistor (0.3Ω), continuous output current: HR1124S: 1.2A (SOP8); HR1154D: 1.5A (DIP8); ● Low standby current (0.01ua) and low static working current (0.2mA) ● Low working voltage ● Wide voltage supply, 1.8V-6.8V ● Built-in overwhelming off protection circuit ● Comply with ROHS standards, read the full text, technology area Industrial Internet requires ICT and OT closely integration, management innovation and technology innovation is always on the road Ti launches new DLP® PicoTM controller for compact mass markets Count the global industrial control system security attack event Industrial Control Systems will bring unrecognizable consequences if it is hacked PLC programming algorithm, simulation order control method
