• What is CMOS output?
    • CMOS output (complementary output) normally consists of a Pch MOS at the high output stage and an Nch MOS at the low output stage. An alternative configuration is NMOS output, comprised of Nch MOSFETs at both high and low sides. However, the high side Nch MOSFET requires a step-up voltage source for driving, such as a charge pump or bootstrap circuit, which necessitates an external capacitor.
      ROHM's H-bridge drivers are all CMOS type, eliminating the need for additional step-up circuits and external capacitors.
