The MC33262 are active power factor controllers specifically designed for use as a preconverter in electronic ballast and in off?line power converter applications. These integrated circuits feature an internal startup timer for stand?alone applications, a one quadrant multiplier for near unity power factor, zero current detector to ensure critical conduction operation, transconductance error amplifier, quickstart circuit for enhanced startup, trimmed internal bandgap reference, current sensing comparator, and a totem pole output ideally suited for driving a power MOSFET. Also included are protective features consisting of an overvoltage comparator to eliminate runaway output voltage due to load removal, input undervoltage lockout with hysteresis, cycle?by?cycle current limiting, multiplier output clamp that limits maximum peak switch current, an RS latch for single pulse metering, and a drive output high state clamp for MOSFET gate protection. Device is available in dual?in?line plastic packages.

Basic Information
Full bridge drivers, or H-bridges, are what are used in brush motor applications. Each IC has an operating voltage range of 6V to 15V and a maximum output current of 2A. The output stage's MOS transistors enable PWM speed control. Motor driver ICs that have been discontinued can be directly replaced thanks to the inbuilt VREF voltage control mechanism. Low-power consumption designs are made possible by these incredibly efficient H-bridge driver ICs.
Features
Built-in Selectable Features Cross-Conduction Prevention Circuit, OCP, OVP, TSD, and UVLO Protection Circuits, One Channel or Two Channels Configuration, VREF Voltage Setting Pin Enables PWM Duty Control, and One or Two Channels Configuration.
Key Particulars
Maximum Output Current: 0.5A, 1.0A, 2.0A;
Output ON-Resistance: 1.5;
PWM Input Frequency Range: 20kHz to 100kHz;
