The IXMS150 is a high performance monolithic 2-channel PWM controller. Implemented in CMOS, the low power IXMS150 precisely controls the current in each of two separate power H-bridge drivers using unique sampling and signal processing techniques. Each channel contains an error amplifier, PWM, feedback amplifier, and protection circuitry. Protection features include over/excess current shutdown, min/max duty cycle clamp, under voltage lockout, dead time insertion, and a shutdown input for over-temp or other external fault circuitry. Other features include a common oscillator, feedforward circuit for motor supply compensation, and an onchip negative bias generator.
