1 / 14 page TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110-8534 JAPAN Ordering number : ENN8412A 32207 TI PC / 12006 MH OT B8-9000 No.8412-1/14 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 SANYO Semiconductors DATA SHEET LB11697V Monolithic Digital IC Brushless Motor Driver IC Specifications of any and all SANYO Semiconductor Co.,Ltd. products described or contained herein stipulate the performance, characteristics, and functions of the described products in the independent state, and are not guarantees of the performance, characteristics, and functions of the described products as mounted in the customer's products or equipment.
