Bi-CMOS IC
For Brushless Motor Drive
LV8136V
Direct PWM Drive, Quiet Predriver IC
Overview
The LV8136V is a PWM system predriver IC designed for three-phase brushless motors.
This IC reduces motor driving noise by using a high-efficiency, quiet PWM drive (150-degree drive system).
It incorporates a full complement of protection circuits and, by combining it with a hybrid IC in the STK611 or STK5C4
series, the number of components used can be reduced and a high level of reliability can be achieved. Furthermore, its
power-saving mode enables the power consumption in the standby mode to be reduced to zero. This IC is optimally
suited for driving various large-size motors such as those used in air conditioners and hot-water heaters.
Features
• Three-phase bipolar drive
• Quiet PWM drive (150-degree current-carrying)
• Supports drive phase control (15-degree lead angle for 150-degree current-carrying drive. From this state, a lead angle
from 0 to 28 degrees can be set in 16 steps)
• Supports power saving mode(power saving mode at CTL pin voltage of 1.0V (typ) or less; I
off)
= 0mA, HB pin turned
CC
• Supports bootstrap (maximum duty limit)
• Automatic recovery type constraint protection circuit
• Forward/reverse switching circuit, Hall bias pin
• Current limiter circuit, low-voltage protection circuit, and thermal shutdown protection circuit
• FG1 and FG3 output (360-degree electrical angle/1 pulse and 3 pulses)
