描述 Description

LV8850GA is a pre-driver IC which is three-phase, sensorless and drives with PWM. LV8850GA drives without a hole sensor, which is suitable for driving high-current motor which requires high reliability and long life.

特性 Features

VCC+7V charge pump booster circuit for output drive
Integrated Synchronous Rectifier circuit (Selected by SYNSEL pin)
PWM or DC input signal is selectable (Selected by CTLSW pin)
Adjustable PWM frequency (By the external capacitor at DC input mode)
Integrated Current Limit circuit (highly accurate detection by using sensing (RFGND) pin for monitoring)
Integrated Forward / Reverse rotation switch circuit (Selected by F/R pin)
Integrated Lock Protection circuit with auto-recovery
Output Lock Protection signal (RD pin) / Output 1-hole FG signal (FG pin)
