Both series feature a unique undervoltage lockout function which puts the outputs in a defined low state in an undervoltage condition. In addition, the low "on" state resistance of these bipolar drivers allows significantly higher output currents at lower supply voltages than with competing drivers using CMOS technology. Logic The MC34151 series is pin-compatible with the MMH0026 Input A and DS0026 dual MOS clock drivers, and can be used as drop-in replacements to upgrade system performance. The MC34152 noninverting series is a mirror image of the inverting MC34151 series. These devices can enhance the drive capabilities of first generation switching regulators or systems designed with CMOS/TTL logic devices. They can be used in dc-to-dc Logic Input B converters, motor controllers, capacitor charge pump converters, or virtually any other application requiring high speed operation of power MOSFETs.
