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.

Control chip: HR1124S
