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 Monolithic Digital IC Direct PWM Drive Brushless Motor Predriver IC Ordering number : EN8412A |
