Details
OverviewThe LB1823 is a predriver IC developed for driving power brushless motors in office automation applications. A motor driver circuit with the desired output power (current and voltage) can be constructed by attaching either a driver array or discrete components at the output. The LB1823 output supports direct PWM drive and thus allows the implementation of low-loss drive circuits. Additionally, the LB1823 includes several associated circuits, such as a speed control circuit, and FG amplifier, and an integrating amplifier, on chip.Features• Direct PWM drive output• Crystal oscillator circuit• Speed discriminator plus PLL speed control system• Lock detector output• Forward/reverse switching circuit• Braking circuit (short braking technique)• Start/stop switching circuit• Over current limiter circuit (OCL)• Thermal shutdown circuit (TSD)• Built-in FG amplifier, integrating amplifier• Shunt regulator output (7.0 V)
