This pump driving module uses a single-channel H-bridge driver chip-HR1124S.
The H-bridge driving part of HR1124S uses low on-resistance PMOS and NMOS power tubes, which can reduce chip’s power consumption and make the chip work safely for a longer time. In addition, HR1124S has low standby current and low quiescent operating current.

PWM can regulate the speed of the motor, for example, in clockwise, INA is high level and INB is low level, the rotation speed is the fastest.
If INA inputs PWM wave, and INB also maintains low level; the duty cycle of INA is the speed regulation ratio.
If INA keeps high levels and INB inputs PWM wave; the duty cycle of INB is the speed regulation ratio.

Description

This pump driving module uses a single-channel H-bridge driver chip-HR1124S. The H-bridge driving part of HR1124S uses low on-resistance PMOS and NMOS power tubes, which can reduce chip’s power consumption and make the chip work safely for a longer time. In addition, HR1124S has low standby current and low quiescent operating current.

PWM can regulate the speed of the motor, for example, in clockwise, INA is high level and INB is low level, the rotation speed is the fastest.

If INA inputs PWM wave, and INB also maintains low level; the duty cycle of INA is the speed regulation ratio.

If INA keeps high levels and INB inputs PWM wave; the duty cycle of INB is the speed regulation ratio.
