LB11696V

Ordering number : ENN8087 SANYO Semiconductors DATA SHEET Monolithic Digital IC LB11696V Overview Direct PWM Drive Brushless Motor Predriver IC The LB11696V 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 LB11696V provides a full complement of protection circuits allowing it to easily implement high-reliability drive circuits. This device is optimal for driving all types of large-scale motors such as those used in air conditioners and on-demand water heaters. Functions and 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 Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Supply voltag...
