LB11697V

LB11697V Monolithic Digital IC Direct PWM Drive Brushless Motor Predriver IC http://onsemi.com Overview The LB11697V is a direct PWM drive predriver IC designed for three-phase power brushless motors. A motor driver circuit with the desired output power (voltage and current) can be implemented by adding discrete transistors in the output circuits. Furthermore, the LB11697V provides a full complement of protection circuits allowing it to easily implement high-reliability drive circuits. Note that the LB11697V is a modified version of the LB11696V in which the output logic has been optimized for 12 V system motors. This allows the number of external components to be reduced in application circuits. Features  Three-phase bipolar drive  Direct PWM drive (controlled either by control voltage or PWM variable duty pulse input)  Built-in forward/reverse switching circuit  Start/stop mode switching circuit (stop mode power saving function)  Built-in input amplifier  5 V regulator output (VREG pin)  Current limiter circuit (Supports 0.25 V (typical) reference voltage sensing based high-precision detection)  Undervoltage protection circuit (The operating voltage can be set with a zener diode)  Automatic recovery type constraint protection circuit with protection operating state discrimination output (RD pin)  Four types of Hall signal pulse outputs  Supports thermistor based thermal protection of the output transistors SSOP30 (275 mil) ORDERING INFORMATION See detailed or...
